Introduction
Biological stress factors such as bacteria, fungi, viruses, and pests can lead to losses in yield and quality before and after harvest. An estimated10 to 23 percent loss is caused by fungal pathogens, along with an additional 10 to 20 percent post-harvest loss. Unlike animals, plants do not possess a highly developed immune system or mobile immune cells. They possess highly sophisticated defense mechanisms based on their structural, chemical, and protein composition. The defense responses of plants to different pathogens are influenced by factors such as the stage of plant development, the pathogenicity of the pathogen, and the environmental conditions. Recognizing the importance of genes that resist biotic stressors, it becomes clear that they are invaluable natural resources for sustaining agricultural productivity and minimizing crop losses36. Any physiological abnormality or significant disruption in the average health of a plant is considered a disease. Living agents, like fungi and bacteria, and environmental factors such as nutrient deficiency, drought, and lack of oxygen, excessive temperature, ultraviolet radiation, and pollution can all contribute to disease development. Plants have developed diverse constitutive and inducible defenses to safeguard themselves from harm. Disease resistance is decreased pathogen growth on or within the plant11. It indicates a lower disease occurrence in one genotype than the susceptible variety and is a relative characteristic. Typically, the reproduction rate is significantly decreased, which restricts disease transmission. Plants have varying levels of resistance to different pathogens, with some being more susceptible to specific pathogens while being resistant to others. This resistance is often specific to particular species or strains of pathogens.

1. Introduction
Internationally, agricultural systems have predominantly prioritized the production of a large volume of food rather than the nutritious value of the food produced (McGuire, 2015). According to the Food and Agriculture Organization (FAO), around 792.5 million individuals in developing countries experience malnutrition due to insufficient access to food that is rich in nutrients (FAO, 2020). In response to this difficulty, biofortification has garnered considerable interest. Biofortification is a process that involves the improvement of food crops via the application of traditional breeding methods, sophisticated biotechnology techniques, and agronomic practices (McGuire, 2015). This will aid in mitigating the problem of “hidden hunger” caused by the deficiency of vital micronutrients in impoverished and developing nations (Khush et al., 2012). India has a population of approximately 15.3 percent that is undernourished.
Regarding global rankings, India is ranked 101 out of 116 nations, with a score of 27.5 (Yadava et al., 2022). The increasing global population and the significant consequences of climate change have presented a demanding obstacle to achieving worldwide food security (FAO, 2020).

Technology Scouting and Innovations in Technology Incubation
Technology scouting and innovations in technology incubation have a symbiotic relationship, fuelling each other for the benefit of budding startups and the broader technology ecosystem. Let’s dive deeper into their individual roles and how they interact:
Technology Scouting
Technology Scouting is the process of discovering, analyzing and evaluating new or existing technologies that will help them with their innovation process. In simple terms, it is a process for companies to find the necessary technology outside the company.
Hunting for promising technologies: Scouts actively search for emerging technologies, patents, research advancements, and market trends across various sectors.
Evaluating potential and fit: They assess the technical feasibility, market potential, and compatibility with the needs of incubators and their supported startups.
Connecting innovators and ventures: Scouts bridge the gap between technology creators (researchers, inventors, startups) and potential users (incubators, established companies).
Fuelling innovation pipelines: Technology scouting helps incubators access a wider range of technologies and ideas, enriching their portfolio and diversifying the innovations supported.

Technology Promotion
The activity of promoting the transfer of technology by creating opportunities, advertising and organizing technology events.
Promotion is a marketing tool, used as a strategy to communicate between the sellers and buyers. Through this, the seller tries to influence and convince the buyers to buy their products or services. It assists in spreading the word about the product or services or company to the people. The company uses this process to improve its public image. This technique of marketing creates an interest in the mindset of the customers and can also retain them as a loyal customer.
Promotion is a fundamental component of the marketing mix, which has 4 Ps:
1. Product (Warranty, features, variety, quality, design, packaging, brand name)
2. Price (List price, discounts, payment terms, credit)
3. Place (channels, coverage, Types of promotion locations, transportation, inventory)
4. Promotion (advertising, self-marketing/personal, sales promotion, public relations, direct marketing, trade shows, events).

Basics of Technology Incubation
Technology incubation is a fascinating process that fosters the growth of innovative startups and businesses with high-potential technology. It provides a supportive environment and resources for early-stage companies to develop their ideas, validate their business models, and navigate the challenges of commercialization.
Here’s a breakdown of the key aspects of technology incubation: What happens in a technology incubation?
Pre-incubation: Startups with promising ideas can receive initial guidance and support to refine their concepts and develop a business plan.
Incubation: Selected startups gain access to shared office space, mentorship from experienced professionals, networking opportunities, and access to funding sources.
Post-incubation: Graduated startups continue to receive support in areas like marketing, legal advice, and investor relations as they scale their businesses.
Benefits of Technology Incubation
Reduced risks: Startups can test their ideas and validate their market potential before investing significant resources.
Access to resources: Incubators provide vital resources like office space, equipment, and software, reducing the financial burden on startups.

Technology Assessment and Refinement
What is Technology Assessment?
Technology assessment serves as a method or tool for forecasting future technological needs. It helps in envisioning or predicting potential technological developments required by users and in identifying areas where existing technologies can be improved. In agriculture, evaluating a technology means understanding its worth or effectiveness. This evaluation can be done by researchers, farmers, or other relevant stakeholders. The knowledge obtained from such evaluations is essential for creating new technologies, improving existing ones, and ensuring their successful adoption by end users.
The approach to technology assessment varies depending on who is conducting the evaluation, the purpose behind it, and the specific characteristics of the technology being assessed. It is commonly defined as the organized and intentional use of knowledge, skills, and experience to carry out a task or deliver a service that contributes to the well-being of society.
Technology Assessment: Definition and Objectives
According to Strasser (1972), technology assessment is a structured approach to planning and forecasting that identifies various options and associated costs. It considers not only economic factors but also environmental and social impacts, both internal and external to the technology being evaluated. The assessment places emphasis on analyzing both the positive and negative consequences of technologies. As such, institutions involved in the development, refinement, and dissemination of agricultural technologies have a significant stake in conducting technology assessments.

Basics of Technology Commercialization
Technology, a ubiquitous force shaping our world, can be understood from various angles. Here’s a breakdown of its definition, functions, and the fascinating process of its advancement.
Definition
At its core, technology is the application of scientific knowledge for practical purposes. It’s not just about gadgets and gizmos; it encompasses a vast array of systems, processes, and tools that we use to transform the world around us and solve problems. This includes everything from the humble wheel to the intricate workings of artificial intelligence.
Functions
Technology serves a multitude of functions, broadly categorized into:
Simplifying tasks: From automated manufacturing to self-driving cars, technology automates and streamlines processes, saving time and effort.
Enhancing communication and connection: From the internet to social media, technology bridges geographical barriers and fosters global interaction.
Expanding our knowledge and understanding: Scientific instruments, telescopes, and advanced data analysis tools enable us to explore the universe, delve into the microscopic world, and gain deeper insights into various fields.

Introduction

Intellectual property encompasses the products of human creativity, including inventions, artistic works, and commercial symbols. It can be categorized into two main types: industrial property and copyright. Industrial property covers patents, trademarks, industrial designs, and geographic indications of source. Copyright, on the other hand, protects literary and artistic works such as novels, poems, films, music, and visual arts. Intellectual property rights (IPRs) also extend to related areas such as performers’ rights, recording producers’ rights, and broadcasting rights. These rights safeguard the interests of creators by granting them exclusive ownership over their creations. However, unlike tangible property, intellectual property lacks physical characteristics and must be expressed in a discernible manner to be protected.

Traditionally, intellectual property comprised four primary types: patents, trademarks, copyrights, and trade secrets. However, the concept has evolved to encompass newer forms, such as geographical indications, plant variety protection, semiconductor and integrated circuit (IC) protection, and undisclosed information. This expansion reflects the changing landscape of innovation driven by rapid technological, scientific, and medical advancements.

Introduction

Breeders expect a new variety to show high performance for yield and its contributing characters along with other physiological and nutritional traits. A variety is said to be superior not only for its higher economic yield, but also for its consistent performance over a wide range of environmental conditions. But the performance of a particular variety is the resultant of its genetic constitution and the environment in which it has been grown. Particular variety may not exhibit same phenotypic performance under different environments, or different varieties may perform differently to a specific environment.

The basic cause of differences in the stability of different genotypes is the interaction effect of genotype and environment, known as genotype × environment (G × E) interaction (GEI). The term environment refers to the uncontrolled external conditions that affect expression of genes of an individual genotype such as the annual rainfall, dry spells, soil fertility gradients, waterlogging, depth and texture of soil, and photoperiod and incidence of disease or pests. However, prediction of GEI is seldom possible with available and known factors. Therefore, the environmental factors can be categorized as predictable and unpredictable environmental factors (Table 1).

Epigenetics is a new field of research in plant biology, which aims to provide a powerful tool to improve crop productivity, adaptability, and resistance to biotic and abiotic stresses. In recent years, researchers have begun to explore the potential of epigenomics in plant breeding, providing breeders with an alternative to genetic engineering, addressing concerns related to genetically modified organisms (GMOs) in agriculture. In particular, epigenetic markers (epimarkers) are chemicals which regulate genes by sitting over the DNA sequence; they explore the consequences of thermal and ionic variation on the behavior of plant under stress conditions. Moreover, epialleles may be promising sources of new variation of traits that are controlled by genes that are not detrimentally regulated. In this chapter, we provide an overview of the current state of the art in epigenomic research, focusing on the impact of next-generation sequencing (NGS) on epigenomes, as well as the potential use of epigenetics in crop breeding.

Introduction

Epigenetics is the study of heritable changes in gene expression that occur without alterations in the DNA sequence. It involves modifications of the DNA or associated proteins that can influence gene activity and expression. Most cells in an organism share the same genes, although they can be very diverse from one another. This is due to the fact that not all genes are active in all cells at the same time. The epigenetic context of a gene, or its accessibility to transcription, can tell whether the gene is likely to be active or not (Klemm et al. 2019). Indeed, the nuclear genome is found as a dense combination of long DNA strings wrapped around specialized proteins called histones to create nucleosomes (Samo et al. 2021). These nucleosomes can be further packed together to form even denser 3D formations that are sometimes visible under a microscope, giving rise to the term “chromatin”.

Conventional crop breeding requires a substantial investment of time, space, and resources for the selection process and the subsequent crossing of desired plants. The time taken for the complete seed-to-seed cycle is a critical constraint in the advancement of plant research and breeding. The concept of speed breeding holds the promise of diminishing the duration necessary for the entire process of cultivar development, from creation to introduction and eventual commercial availability, thereby enhancing the improvement of both food and industrial crops. It revolves around optimizing conditions such as light intensity, temperature, and daylight duration (22-hour light, 22°C day/17°C night, and high light intensity). This approach enhances photosynthesis, triggering early flowering, and, in combination with yearly seed collection. The adoption of speed breeding shows promises in realizing nutritional security and promoting sustainable agriculture for the future rising population. The technique’s integration with advanced genomics and gene editing opens doors to precise trait incorporation. Moreover, speed breeding reduces resource consumption, aligning with sustainability goals. As local adaptations become feasible, it empowers diverse regions.

Wide hybridization or distant hybridization is crossing between two different species or genera, and has been used successfully to transfer genes and to create new crop species. Wild plant species related to crop plants form an important source of useful traits for quality improvement and biotic and abiotic stress tolerance. Cultivated species has lost many beneficial traits for stress tolerance in the process of domestication and selection, which resulted in uniformity in many agronomic traits. Although there have been multiple cases of valuable tolerant genes being transferred from wild rice to cultivated rice, it is now necessary to look at new breeding and selection strategies that may be applied to wide hybridization. It breaks the species barrier for gene transfer and makes it possible to transfer the genome of one species to another, which results in changes in genotype and phenotype of the progenies. The barriers in wide hybridization occurs as prezygotic and postzygotic barriers. Techniques of chromosome doubling, bridging species, protoplast fusion, and embryo rescue are highly beneficial in recovering fertile progenies by overcoming various barriers in wide crossings. Broadening the gene pool of a crop is an important plant breeding method as it can enhance tolerance of major biotic and abiotic stresses and improve the quality characteristics of the plant.

Introduction

Crop improvement lies at the heart of ensuring food security, agricultural sustainability, and the resilience of our farming systems. As we confront a world characterized by climate variability, emerging pests, and a growing global population, the need for innovative approaches to crop enhancement becomes paramount. This is where the concept of pre-breeding steps in: a fundamental phase that acts as a bridge between the untamed genetic diversity of wild plants and the refined traits of cultivated crops. Pre-breeding represents the exploration, identification, and incorporation of valuable genetic traits from the vast array of plant species that often remain on the fringes of agricultural attention. These “wild relatives” and underutilized varieties possess traits that have evolved over time to withstand diverse environmental stresses, combat diseases, and adapt to changing conditions. Pre-breeding aims to tap into these reservoirs of genetic potential, merging them with the qualities we value in our cultivated crops. At its core, pre-breeding is a scientific journey of discovery and innovation. It involves the strategic selection and hybridization of plant materials, guided by a vision of enhancing crop performance across multiple fronts. The goal is to create crop varieties that are not only productive and high yielding, but also equipped to thrive in the face of evolving challenges. This involves a delicate dance between tradition and cutting-edge techniques as well as collaboration between breeders, geneticists, and researchers (Qureshi et al. 2014).

Two cornerstone methodologies in genetics, forward genetics and reverse genetics, illuminate the intricate connection between gene sequences and their functions. Forward genetics traditionally entailed laborious steps, beginning with the observation of mutants and culminating in the identification of causal genetic alterations. While effective, this approach was time-consuming and limited in scalability. Recent innovations have revolutionized forward genetics with next-generation sequencing (NGS), genome-wide association studies (GWAS), CRISPR (clustered regularly interspaced short palindromic repeats)-based screens, and advanced computational techniques. These advancements deliver precision and efficiency, enabling researchers to explore gene function on an unprecedented scale. In contrast, reverse genetics initiates its journey armed with sequence data and harnesses the manipulation of genes to observe resultant phenotypic shifts. Traditional reverse genetics, though invaluable, faced challenges like limited precision and scalability. Cutting-edge approaches have transformed the landscape. Techniques such as prime editing, base editing, high-throughput functional genomics, single-cell genomics, and synthetic biology offer unparalleled precision and capacity. They empower scientists to scrutinize gene function at the single-cell level, conducting precise genome editing and large-scale functional genomics studies. These strides in forward and reverse genetics have charted new territories for genetic research.

The whole genome sequencing helps the researcher to identify the desired gene and make it useful for the breeding program by transferring that particular gene into improved cultivar. Since, the whole genome sequence is not available for all crops and animals; there is a need of advanced techniques to overcome this problem. One such technique is TILLING (Targeting Induced Local Lesions IN Genomes) and its related technique called Eco-TILLING. TILLING is a reverse genetic approach used to identify the point mutation created by chemical mutagen in the mutagenized population. The chemical mutagen is most widely used and it will create allelic series of mutations which include nonsense, missense, or splice site mutation. The individuals with mutation were pooled by two-dimensional or three-dimensional pooling techniques. These mutations were identified by the formation of heteroduplex complex in the mutated region of the gene. Then, the heteroduplex is cleaved by S1 nuclease family enzyme and were examined in gel electrophoresis which distinguishes heteroduplex from homoduplexes. Now, the identified mutants in gel electrophoresis were subjected to sequencing for confirmation. Eco TILLING is similar to the TILLING except for the mutant population, as we use the natural mutant population in Eco-TILLING; whereas in TILLING we use the artificial mutant population and also pooling is done with reference sample in Eco-TILLING. The advantage of TILLING is that it is a cost-effective, rapid screening of mutant population and a nontransgenic approach as it does not require biosafety measures.

Genome editing has revolutionized plant breeding, offering precise and efficient methods to enhance crop traits. This chapter provides an overview of genome editing’s principles, applications, challenges, and future prospects in plant breeding. The chapter explores genome editing technologies, with a focus on CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats-associated protein 9), TALENs (transcription activator-like effector nucleases), and ZFNs (zinc finger nucleases). CRISPR-Cas9, in particular, has become the go-to tool for precision breeding, allowing scientists to target and modify specific genes with unprecedented accuracy. Applications of genome editing in plant breeding are diverse. It enables the development of crops with enhanced disease resistance, drought tolerance, and improved nutritional content. Additionally, genome-edited crops reduce environmental impact by requiring fewer chemical inputs and promoting sustainable farming practices. Accelerated breeding shortens the time needed to create new crop varieties, addressing urgent agricultural challenges. Looking ahead, the future of genome editing holds exciting possibilities. Continuous advancements in technology promise even more precise editing tools and high-throughput capabilities. Precision breeding will become the norm, allowing for tailored crop varieties and customized agricultural practices.

Introduction

The main goal of plant breeding is to increase crop yield and the second goal is to improve quality, develop light- and heat-insensitive varieties, tolerance to biotic and abiotic stresses, simultaneous maturation, and water and nutrient use. Efficiency, elimination of toxins, and cultivation of different product groups allow to achieve high agricultural yields and sustainable development. Better understanding and development of genetics has increased the efficiency of plant breeding to achieve desired goals in agricultural crops. Effective and efficient use of molecular markers in crop improvement programs increases selection efficiency and productivity and accelerates the growth cycle to create new varieties with good results. Marker assisted selection (MAS) is a technique that uses markers (morphological, biochemical, or DNA/RNA variation-based markers) to indirectly select for traits of interest (e.g., productivity, disease, genetic determinants resistance, abiotic stress tolerance and/or quality). This process is used in plant and animal breeding. The rapid development of biotechnology has allowed breeders to develop better selections to replace traditional selections based on phenotypic pedigree.

Transgenic crops, developed through genetic engineering techniques, have revolutionized modern agriculture by conferring novel traits that enhance yield, quality, and resilience. This chapter delves into the intricate interplay between the scientific advancements in breeding approaches for transgenic crops and the critical ethical concerns and regulatory frameworks that accompany them. The chapter begins by introducing the concept of transgenic crops and provides an overview of the diverse breeding techniques employed to manipulate plant genomes. These techniques include Agrobacterium mediated transformation, biolistic transformation, CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats–associated protein 9) genome editing, RNA interference (RNAi), and site-specific integration methods. Each method is presented within the context of its potential benefits and limitations. The subsequent sections address the ethical considerations that arise from the creation and deployment of transgenic crops. The potential ecological and biodiversity impacts, cross-contamination risks with conventional crops, and issues related to patenting genetically modified organisms (GMOs) are explored. Furthermore, the chapter examines the ethical implications of genetically modified crops on human and animal health and questions surrounding the monopolization of seed resources. Looking to the future, the chapter outlines emerging breeding technologies and anticipates potential challenges in ethical consideration and regulation.

Introduction

One of the biggest problems emerging for the survival of the people in the future is food security. To feed an anticipated nine billion people by 2050, the globe would need to produce roughly twice as much food as it does today. In order to properly accomplish this aim, food production must be elevated sustainably on currently available arable land while addressing the problems brought on by climate change. Over the past five decades, crop yields have steadily increased due to crop breeding programs and better management practices. The rate of yield improvement has, however, reached a plateau (Grassini et al. 2013). The noncompounding yearly yield growth of 0.9% for wheat at the present time, world output rises by 38%, is quite small, and is unable to fulfill expected demand levels by 2050. Therefore, the most beneficial course of action is to investigate more effective, higher-yielding crops (Ray et al. 2013).

Historically, the genetic improvement of wheat has been accomplished by sexual hybridization between related species, giving rise to a large number of cultivars with excellent agronomic performance and high yields. The main methodology for improving cereal crops is still traditional plant breeding, sometimes in combination with traditional cytogenetic methods (Salina et al. 2015). Cereal crops immediately became the top targets for genetic modification due to the worldwide importance of cereal grains in human diets. Over the past 10 years, wheat genetic technology for processing has advanced quickly.
