Introduction
Plant breeding and genetics are at the forefront of agricultural innovation, playing a crucial role in enhancing crop traits to meet the ever-growing demands for food, fiber, and fuel. This chapter delves into the scientific principles, methods, and modern advancements in plant breeding and genetics, providing a comprehensive understanding of how these disciplines contribute to global food security and environmental sustainability. The chapter begins by exploring the fundamental principles of plant breeding, including heredity, genetic variation, selection, and hybridization. These concepts form the foundation for developing new plant varieties that exhibit desirable traits such as improved yield, disease resistance, and environmental adaptability. The importance of genetic variation is emphasized as a key driver of plant improvement, with discussions on the sources of genetic variation, the role of germplasm resources, and the impact of genetic diversity on plant adaptation. As the chapter progresses, various breeding techniques and strategies are examined, including mass selection, pedigree breeding, backcrossing, and markerassisted breeding. These methods are crucial for developing new plant varieties that can withstand the challenges posed by climate change, pests, and diseases. The chapter also addresses the role of genomics in plant breeding, highlighting the significance of genomic selection, gene editing, and bioinformatics in accelerating the breeding process and enhancing crop traits. The chapter further explores the controversial topic of genetically modified organisms (GMOs), discussing the principles of genetic engineering, the rise of genetically modified crops, and the associated controversies and concerns. The importance of GMOs in addressing global food security and environmental challenges is also discussed, providing a balanced perspective on their potential benefits and risks. The chapter concludes by emphasizing the critical role of plant breeding and genetics in ensuring food security and combating global warming. By developing climate-resilient crop varieties, improving water efficiency, and enhancing disease and pest resistance, plant breeding and genetics can contribute to sustainable agricultural practices that reduce greenhouse gas emissions and conserve natural resources

3.1 Introduction 
The continuous rise in CO2 levels is poised to culminate in a profound global warming impact. Projections suggest that by 2030, CO2 levels could nearly triple, driven by the burgeoning population of motor vehicles. This pressing issue underscores the urgency for the current generation to scrutinize its fuel choices and explore alternative options. Biomass emerges as a pivotal contender, offering a trinity of fuel phases. Escalating petroleum prices and growing apprehensions about the role of fossil fuels in contributing to global warming have spurred a quest for biofuels, recognized for their environmentally friendly attributes. The worldwide energy consumption has increased by an astounding 4 to 5% due to the combination of industrialization and the growing human population. Energy insecurity presents a number of puzzles, including rapidly decreasing fossil fuel reserves due to rapid industrialization, skyrocketing gasoline prices, growing dependence on Middle Eastern oil supplies, and the deleterious effect of fossil fuels on greenhouse gas emissions. (Fig 3.1). Figure 1. Air pollution due to fossil fuel smoke from industries & transportation The UN's June 1992 Earth Summit in Rio de Janeiro set the stage for addressing environmental issues such as acid rain and the greenhouse effect caused by greenhouse gas (GHG) emissions. The goal of the Kyoto Protocol, an agreement between Russia, Japan, and Europe, is to reduce CO2 emissions. The ability of first-generation biofuels to lower CO2 emissions has drawn attention. But there is a lot of criticism about how they use land and how it affects the supply of food. A more complex option is provided by secondgeneration biofuels, which are made of leftover animal fat and lignocellulosic biomass. The third generation focuses on algae, namely single-celled organisms (SCO), as a viable substitute in the fuel industry. Within this discourse, "biofuels" refer to chemicals that are enhanced with energy. When burned, biofuels release fewer toxic emissions than fossil fuels, making them renewable resources. Furthermore, no carbon dioxide (CO2) is emitted into the environment by them; instead, any carbon released during combustion is absorbed by plants as they grow.

11.1 Introduction
In the preceding chapter 10, we have discussed in detail, the test procedures for which it has been assumed that the sample size n is large, (i.e n >,30). Those tests are also known as approximate tests or z tests. But in case when sample size n is small i.e. n<30, the approximate test fails to deal with such problem and we apply the theory of exact sample, for small sample tests. The exact sample tests however can be applied to large samples also though the converse is not plausible. In all the exact sample tests, the basic assumption is that the parent population is normally distributed.
In this part we will discusse in details the exact sample tests (based on exact sampling distributions namely snedekor’s F, student’s t and chi square (χ2) distributions. These distributions will be simply introduced in short because main emphasis has to be given only on the test procedures based on them.

Summary

Molecular farming is the large scale production of pharmaceutically important and commercially valuable proteins in plants and animals. Molecular farming in plants has the potential to provide an inexpensive and convenient system in the production of unlimited quantities of recombinant proteins for use as therapeutics, diagnostics, vaccines, antibodies, plasma proteins, cytokines and growth factors. Plants are also being used for the production of oils, starches, plastics, enzymes for food processing and other uses and spider silk etc. However, quality and safety of the final product and wider effects of molecular farming on health and environment need to be addressed. The benefits of molecular farming should not be outweighed by risks to human health and environment.

INTRODUCTION

Meat is the flesh of animals that is used for food and consists of muscle, fat and bone. If the muscle which is commonly known as the lean meat, is examined under the microscope, it is seen to be made up of bundles of fibers held together by a thin membrane called connective tissue. Further study reveals that these fibers are in readily hollow tubes that vary in length in different animals and in different muscles in the same animals that are filled with a fluid, sometimes called muscle juice, which is known to contain protein, minerals and extractives. The forms of protein in the muscles are myosin (a globulin) and myogen (an albumen) and in addition, on red meats, hemoglobin.

Generally microorganisms are so small and colourless in their natural state that it becomes difficult to observe them clearly under microscope. Stains and dyes, which are colouring agents, are used by biologist for better understanding of the morphological and anatomical structures of the organisms under study. Stains are prepared with great care and specification to get satisfactory result, while dyes are not as exacting in their characteristics.

Dyes are of two types, natural and synthetic. The natural dyes are used for histological purposes, whereas the synthetic dyes for bacterial stain. Usually dyes which are derivatives of cyclic compound benzene of benzole, are prepared from one or more substances found in coal-tar, and so are called coal-tar dyes. Chemically dyes are organic compounds containing both chromophore and auxochrome groups linked to benzene rings. Chromophore group provides the compounds the property of colour and thus benzene containing chromophores are called chromogens. It has no affinity to combine with fibres or tissue and as such not called dye. For being a dye, compound should contain an auxillary group which provides the compounds the properties of electrolytic dissociation.

The dyes may be acidic, basic or neutral. The acidic dyes are eosin, acid fuchsine and picric acid whereas the basic dyes are safranin, methylene blue, crystal violet etc. The acidic dyes ionize to give the dye portion of molecule a negative electrical charge. They are salts of sodium, potassium, calcium, magnesium etc. The basic dyes ionize to give the dye portion of molecule a positive electrical charge and are salts of chlorides, sulphates or acetates.

Application of HACCP concept in surveillance & quality assurance programs for raw, frozen, canned, cured, irradiated, cooked, chilled, MAP & freeze dried products.

HACCP

Hazard analysis and critical control point (HACCP) is a system that identify, evaluate and control hazards that are significant for food safety (CAC, 2003). It is a science based systematic approach that assesses hazards and establishes control systems to focus on prevention rather than end product testing. It enhances the safety of the product from biological, chemical, and physical hazards in a production process. It provides way to demonstrate competence to consumers and compliance with legislative requirements.

6.1. History

HACCP was originally developed by Pillsbury Company in 1959 to produce zero defect food for astronauts of National Aeronautics Space Administration (NASA) in USA. In 1971, the HACCP concept was presented at the United States National Conference on Food Protection. The first major document on HACCP was approved by the National Advisory Committee on Microbiological Criteria for Foods (NACMCF) in 1989. The Codex then issued the first HACCP guidelines in 1993, which was adopted by the FAO/WHO Codex Alimentarius Commission (CAC). The USFDA’s Seafood HAACP program became mandatory in USA since 1997. The European Union, in 2004, laid down the general hygiene requirements of all food business operators (EC Regulation 852/2004) and the additional specific requirements for foods of animal origin, including live bivalve mollusks and fishery products which (Regulation EC 853/2004). The United States Food Safety Modernization Act 2011 became the latest enforcement of food safety measures to protect public health. Thus, HACCP has become an International reference system for food safety assurance.

Introduction

Vegetables are one of the potential crops in meeting the food requirements and improving the nutritional status of our people. They play a vital role in crop diversification, employment generation, and nutritional security and in improving the economic conditions of farmers.

Our country has made a tremendous progress in vegetable production and ranked as second largest producers of vegetables in the world with a total production of more than 125 million tons per annum. Our estimated demand is about 225 million tons by 2020 AD. This target can be achieved through use of improved vegetable varieties, hybrids and production technologies even with diminishing land and water resources.

In Indian vegetable scenario, IARI has contributed significantly by developing more than 168 improved varieties and 24 hybrids in different vegetables. Apart from high yielding, many of these varieties/F₁ hybrids are resistant to biotic and abitic stresses and also suitable for processing, value addition and export. Besides developing large number of improved varieties and F₁ hybrids of vegetables, IARI has developed/standardized improved hi-tech vegetable nursery and off-season production technologies which require commercialization by the entrepreneurs as these can bring quantum improvement

ABSTRACT

Butea monosperma (Lam.) Taub, knownas ’Flameof the Forest’is used in Indian traditional system of medicine, such as Siddha Ayurveda, and Unani due to its medicinal properties. It is used in treatment of diabetes, diarrhoea, sore throat and reported to possess several biological activities such as anti-asthmatic, anti-diabetic, antifertility, anti-tumor and osteogenic. Recent studies revealed the phytochemicals responsible for osteogenic activity in the bark of B. monosperma. An ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method was developed for identification and simultaneous quantitation of bioactive compounds from B. monosperma. Validation of the developed method was performed according to international conference on harmonization guidelines. Quantitative interpretation showed significant variations in the content of bioactive compounds in different parts of the plant and samples collected from three geographical regions. Principal component analysis was also used to study the quantitative variations of markers.

1. Introduction Proso millet (Panicum miliaceum (L.) belongs to the grass family Paniceae. It is a perennial cropthat grows in summer each year as late-seeded summer crop (Figure 1). Its origin can be traced back to at least 2000 B.C. when it was said to be grown in the Central European regions. Proso millet plant thrives in dry areas such as Africa, Central Russia, Manchuria, Middle East and Northern India and North America’s Great Plains. Proso millet was introduced to Canada in the 17th century and used sparingly as a feed crop in the early 1900s (Rajasekaran and Francis, 2021). This is a low-demand crop and is utilised in organic farming systems across Europe and as an intercrop in the United States. Its shallow root system and resistance to atrazine residue make it a great intercrop between two crops that need a lot of water and pesticides. The last crop’s stubbles entrap more heat into the soil which promotes faster and earlier growth of millet. Hence, it can help to evade summer drought and achieve continual crop rotation (Kalinova and Moudry, 2006). It is an erect herbaceous annual crop with a lot of tillering. Its plant can reach a height of 45-100 centimetres. The stem is thin, with prominently enlarged nodes. The roots are thin and fibrous.

Introduction
Crop improvement is critical for tackling global food security challenges caused by population growth, resource scarcity, and climate change (Singha and Singha, 2024). Traditional breeding techniques, such as Sanger sequencing, have been around for a long, but their accuracy, speed, and usefulness are typically limited. Sanger sequencing is useful for small-scale inquiries, but its laborintensive procedures and limited throughput make it unsuitable for large-scale genome analysis. Molecular marker-based breeding strategies have proven to be effective tools for addressing these difficulties by increasing plant growth and overall quality (Bohar et al., 2020). In this respect, molecular markers like as single nucleotide polymorphisms (SNPs), insertions/deletions (indels), simple sequence repeats (SSRs), and structural variations (SVs) are expected to be useful for future breeding operations (Panahi et al., 2024). The discovery and characterization of these molecular markers is strongly reliant on advances in sequencing technology, namely next generation sequencing (NGS). Furthermore, NGS technologies have shown to be crucial for functional genomics, allowing for large-scale transcriptome and whole genome sequencing across plant taxa (Singh et al., 2024). These vast databases give a comprehensive picture of gene expression and genetic variation, making it easier to identify functional markers linked with certain features (Figure 1). The integration of NGS and bioinformatics technologies has simplified the study of these datasets, enabling more efficient discovery of markers and improving the use of marker-assisted selection (MAS) in breeding programs (Panahi et al., 2024).
The development of high-throughput genotyping technology has enabled substantial SNP-based research, which has improved our understanding of genetic diversity, population structure, and disease association (Yirgu et al., 2023). With the progress of genotyping by sequencing (GBS), SNPs have emerged as the most extensively utilized DNA markers in the twenty-first century (Thomson, 2014). SNP markers have significantly advanced plant breeding across a variety of crops, including tomato (Peterson et al., 2012), maize (Junta et al., 2020), rice (Razak et al., 2020), wheat (Wei et al., 2011), soybean (Kim et al., 2010), oil palm (Maryanto et al., 2020), cassava (Karim et al., 2020), and taro (Helmkampf et al., 2018). Overall, SNP markers have emerged as critical tools for genetic improvement and precision breeding across a wide range of crop species. SNPs initially trailed behind SSRs in DNA fingerprinting because they have fewer polymorphisms

Introduction 
To fight climate change and lessen dependency on fossil fuels, the world urgently needs renewable and environmentally friendly energy sources. Hydrogen has become a promising energy carrier due to its versatility and capacity to generate energy from renewable resources without releasing greenhouse gases into the atmosphere. The world's demand for energy has been steadily increasing as a result of urbanization, economic expansion, and population rise. With an estimated 10 billion people on the earth by 2050, energy consumption is only expected to increase. Fossil fuels, which include oil, coal and gas have been widely used to generate energy and are predicted to do so at least until 2050 (see Fig.6.1) [1]. Figure 1. Global primary energy consumption is broken down by energy source [2, 3]. These fuels generate a large amount of greenhouse gases (GHGs) during combustion, especially carbon dioxide (CO2), which is connected to climate change and global warming. In addition, burning fossil fuels releases particulate matter (PM), sulfur oxides (SOx), nitrogen oxides (NOx), and other pollutants that are harmful for human health. In addition, the unequal distribution of fossil fuel supply has led to increased instability globally and worries about energy security. Numerous nations started making investments in energy from renewable sources as concerns about the environment and energy security have grown. Because they emit little to no greenhouse emissions, renewable energy resources like hydroelectricity, wind, and solar power contribute to lowering the energy industry's overall environmental impact (see Fig.6.2) [4].

3.1 Introduction

Ozone (O₃) is present throughout the atmosphere and can have either positive or negative effect depending on where it is found. The stratosphere (15-50 km) has the largest (90%) concentrations of O₃ (Colls, 1997). Stratospheric O₃ is important as it regulates the transmittance of ultraviolet light to the surface of the earth. Hence reductions in stratospheric O₃ in Polar regions, particularly the Antarctic “ozone hole”, are of concern regarding the health effects of exposure to increased levels of ultra violet (UV) radiation. In the troposphere (0-15 km), O₃ is a toxic pollutant of global importance and it is a major constituent of photochemical smog. Interest in pollutant O₃ and in its effects on living organisms has increased in the last decades as a consequence of the rise in its ground-level concentration and of the widening of its diffusion (Ashmore, 2005). Economic growth requires more energy production, which would result in increased production of NOx and volatile organic compounds (VOCs) precursors for O₃ formation (Ghude et al., 2008).

A press release, also known as a news release, is a brief, compelling document that provides essential information about an event, product, service, or organization. Its primary purpose is to inform journalists, media outlets, and the general public about noteworthy developments in a way that garners attention and encourages media coverage.
Press releases play a crucial role in public relations (PR) strategies, serving as a bridge between organizations and their stakeholders. They are used across various industries to announce product launches, organizational changes, events, awards, and crisis responses, among other key moments.
The Purpose of Press Releases
Press releases serve as a vital communication tool in modern public relations. They enable organizations to connect with their audience, media, and stakeholders effectively. Below is a detailed exploration of the key purposes they fulfill:
1. Informing the Public
The primary goal of a press release is to convey significant updates, announcements, or achievements to the public.
• Sharing News: Whether it’s launching a product, announcing an event, or achieving a milestone, a press release acts as a formal medium to share this news in a professional manner.
• Transparency: Press releases help organizations maintain transparency by keeping their audience informed about developments. This is especially important for businesses, government bodies, and non-profits that engage directly with the public.

Summary

Bioenergy is the subject of increasing attention around the globe and represents an important issue in the present context. The rise of commodities prices, the negative impact on food security, and climate change represent different challenges to be overcome before the full potential of bioenergy can be realized. Bioenergy issues related to agriculture needs special attention for its development. Bioenergy development is always linked with rural economy. Farmers, having the choice to convert their food crops to fuels crops, naturally expect a high return from their farmland, thereby generating a scenario where food production gets depleted. The optimal production of bioenergy can be generated by using the wasteland present in different area. This way, food security for the future generation can be maintained along with optimal growth of bioenergy.

INTRODUCTION

Seed is one of the most vital and important inputs for increasing agricultural production. Commercial flower seed production is an international business involving highly specialized growers. Compared with the production of seeds of cereals, pulses oilseed even vegetable seeds, it is done on a relatively small scale. However, a large number of species are being produced under very different cultural conditions. It seems to have great scope for expansion in developing countries like India, especially under northern India climatic zones having favourable growing conditions, skilled and cheap labour.

Plants belonging to the Rhododendron subgenera Pentanthera (deciduous) and Tsutsusi and Azaleastrum (evergreen) are called azaleas. Azalea belongs to family Ericaceae. Azaleas are one of the favourite ornamental plants used by home owners and professional landscapers. They are used as foundation, accent, individual specimen plants, and as mass plantings. Azaleas are good companion plants, working well in designs with many trees, shrubs and ground covers, offering a variety of landscape options. Azaleas can be found in all ranges of colours, from delicately pink-tinged white to strong, bright red, and there are species that has the startling colour of flame. Its bold colour scheme has caused people to carry it far and wide, for use wherever a sudden note in strong hue is appropriate among the milder expressions of the rest of the flowers. The evergreen azalea, Rhododendron simsii  Planch., is one of the most important pot plants in Western Europe and the USA. The breeding history of this vegetatively propagated plant is a relatively short one, and breeding has been focused on flower characters because the public is continually asking for new flower colours and flower types.

The thoracic cavity (Fig. 3-3 A, B and C) contains lungs and pleura, the heart and pericardium, the great vessels connected with the heart (the aortae, azygos veins and venae cavae), the oesophagus, trachea, the lymph nodes, vessels, nerves and lymphatics. All of these contents except the lungs and pleural sacs are located in the mediastinum, while the lungs along with the pleural sacs are situated on either sides of the mediastinum.

Lungs

The right and left lungs (Fig. 3-3 A and B) are paired organs which occupy greater space of the thoracic cavity. Each lung is enclosed in a double layered bag of serous membrane called the pleural sac. The right lung is larger, almost double in size than the left one. The difference in size is mainly due to an additional lobe called the intermediate lobe and the greater size of an apical lobe of the right lung. Each lung is divided into different lobes formed by deep fissures extending from the ventral border to almost the area of the root of the lung. Each lung is soft, light weighted, spongy and elastic. The surface of the lung is smooth and glistening and it is mapped out into irregular areas indicating the lobules of the lungs. In the fresh, unpreserved cadaver the lung collapses to about one third of its original size and looses its normal shape. The colour in fresh state is pink, in bled animals it is pale grey and in unbled animals it is dark red. In embalmed specimens, the outer surface of the lungs is marked by the imprints of other organs and structures that are related to lungs in the thoracic cavity.
