Introduction

The palmyrah is believed to be a native of tropical Africa. It grows extensively in drier parts of India, Sri Lanka, Myanmar, Thailand, Vietnam, Malaysia and Indonesia. It is recognised as the state tree of Tamil Nadu in 1978, recognising its importance. It has been estimated that there are about 8.6 crores of Palmyra palms existing in India, of which 5.02 crores of palms are alone spread over Tamil Nadu and the remaining 3.58 crores of palms are in Andra Pradesh.

Introduction

Papaya has long been known as the wonder fruit of the tropics and is one of the five major fruit crops of the tropical world. Papaya fruits throughout the year are a remunerative fruit crop which is grown in almost every part of the country. Next to bananas, it has the highest yield and income per unit. It is generally grown as a fruit plant in kitchen gardens, home gardens, or nutrition gardens and later as a commercial fruit. Papaya is usually dioecious, but hermaphrodite and gynodioecious types are also Recognized. It is the most remunerative crop (highest net return/unit area) of any other fruit crop. India is the 4^th largest producer in the world. Karnataka has the highest production and productivity in India. A valuable proteolytic enzyme is called papain, which helps in the digestion of protein-rich foods. Transgenic PRSV resistant varieties: Sunup and Rainbow were created from coat protein genes grown in Hawaii in 1992.

Introduction

Commercial in South Africa, Srilanka, Kenya, Cameroon, Hawai, Zimbabwe and Australia. In India, it is growing wild in Nilgeria, Wynad, Kodaiknal, Coorg and Malabar. It is being cultivated in H.P. Nagaland and Mizoram. Brazil is the world’s largest producer. A rich source of vitamin A, it also contains fair amounts of sodium, magnesium, sulphur and chlorides. It gives a very good squash and is used in jam, jelly, nectar and ice cream making. Dried flowers contain an alkaloid called ‘Passiflorin’, which is used for relieving pain and inducing sleepness.

Introduction

It comes to the market early in the season, particularly the low chilling peaches and growers get remunerative prices due to the non-availability of other fresh fruits in the market. It has high nutritive value, being rich in protein, essential amino acids, minerals, and vitamins. Peaches originated in China, where its culture dates back to 3000 years. Although it is not exactly known how and when the peach reached India, it is opined that some traders might have carried over the stones of peach from China to Kashmir. Peaches were introduced by Mr. Alexander Coutts in Himachal Pradesh in 1870. Later on, its cultivation was initiated in the mid-hills of Himachal Pradesh on the advice of an American horticulturist, Prof. R. W. Hodgson. Some low-chilling varieties of peach were also introduced at Punjab Agricultural University, Ludhiana in 1968 from California. peach with a strong flavour and aroma.

Introduction

Pears are next only to apples in importance, acreage, production and varietal diversity amongst the temperate fruits. The genus Pyrus probably originated in the mountainous regions of Western China. It is a rich source of carbohydrate as sugars, starch and cellulose and minerals like calcium (8 mg/100 g) phosphorous (15 mg/100 g) and sulphur (14 mg/100 g).

Introduction

The pecan is a valuable horticultural gift from North America to the world. In the USA, it is considered the “Queen of nuts” because of its value both as a wild and cultivated nut. As compared to other nut fruits, which have been grown since time immemorial, pecans have been under cultivation only for about one hundred years but have gained enormous popularity. The pecan occupies fifth rank among the leading tree nuts because of its excellent nutty flavor. Pecan nuts are a rich source of fat (72 g), protein (9 g), carbohydrates (15 g) and minerals. Pecan is usually taken roasted or salted to supplement normal diet. Almost 90 % of the nuts are sold shelled and the rest in shell. The nuts are commonly used to add aroma, flavor and crispness, a rich color, or to garnish a large number of dishes. However, most commonly, it is used in baking dishes and in ice cream. Pecan shell, a bay product, is also used to manufacture tannin, charcoal and abrasives in hand soap. The pecan tree has value as a timber too, due to its strength and hardiness. There is a great demand for its veneer and lumber in decorative paneling, fine furniture, and flooring, as well as in pallet manufacturing. good source of phosphoric acid. The most important nut fruit in the world, 5^th in production.

The aim of the breeder is to improve on various economic traits through selection. However, due to the lesser number of parents used, over a period of time, there creeps in the effect of inbreeding and loss of genetic variability which in turn causes depression and loss of fitness. This is more prominent in finite endangered populations and evaluation for genetic variability also forms an integral part of the animal breeding analysis.

Genetic variability is an integral part of domestic animal populations as fitness is directly related to the variability.

Introduction

It was introduced from China into Japan in ancient times, where most of its improvement work has been done. The term “kaki” is Japanese. In the nineteen century, it was introduced from China to many other countries, namely in the USA, Brazil, Italy, New Zealand, Israel, Australia and South East Asia. In India, the European settlers introduced persimmon in hilly states, namely Himachal Pradesh and Jammu and Kashmir in 1921. In India, it is mostly cultivated in the Kullu valley, where it was introduced. At present, it is grown on a limited scale in Jammu and Kashmir, Himachal Pradesh and Uttarakhand. Ripe fruit is delicious, flesh is sweet and jelly-like. The entire fruit is edible except the seeds and calyx. Hexaploid fruit crops, deciduous and monoecious fruit crops. Fruits are highly astringent due to their tannin content. Flowers appear in spring on new growth. Types of flowers: male, female and bisexual. Cross-pollination, Mode of pollination: Insects.

Pollinators are organisms that help to transfer pollen from anther to stigma of the same species for fertilization and thereby produce seeds and fruits. Pollinators belong to diverse groups viz. insects, birds, reptiles, mammals, etc. Insects; bees butterflies, moths, wasps, flies, some types of beetles. Out of insect pollinators, bees are most important pollinator. Insect pollinators are critical to the production of many crops and play pivotal role to maintain the biodiversity. The decline in honeybee and other pollinator populations have more attention of scientific and public concern globally as well as in India. A number of factors have been observed as potential contributors to these declines and no single factor has been identified as the cause. The available science suggests that multiple factors responsible for population depletion and extinction, including loss of habitat and food sources, diseases, viruses, pests, and pesticide exposure. It is also known that certain pesticides can pose an immediate or “acute” threat to the insect pollinators and bees. In order to protect pollinators, the labels of pesticides that pose such risks should specify detailed directions of application to reduce potential exposure.

India is the fastest-growing pet care market in the world and the pet population is of an estimate of 28-29 million, with dogs making up the bulk of pet ownership. The rising pet ownership has led to the growth of the pet care ecosystem comprising retail chains, pet nutrition pharmaceuticals, grooming, toys, clothing, diagnostics, and clinical practice. The pandemic of Covid-19 has a significant impact on the Indian economy; and the pet industry has seen a steep growth during the pandemic period. Isolation and anxiety during the lockdown led to many restorations to adopt furry companions. The veterinary graduate has a lot of opportunities, and it depends upon the individual as to what sector the student wants to pursue. Employment opportunities include diverse areas such as clinical practice, teaching, and research, regulatory medicines, public health, wildlife specialist, or lab animals. Depending upon the interest, one can start exploring options to work for the pet industry and join the Veterinary pet practice clinical.

Introduction

Phalsa is a shrub or small tree of Indian origin. Subtropical bushy fruit plants. It is a very hardy fruit, and hence can be planted on marginal soils, where the rest of the fruits can not be grown. Its cultivation is more popular in the vicinity of cities and towns. Phalsa fruit is liked for its acidic taste, coloured squash and syrup. A woody perennial, arid zone fruit crop. suitable for intercropping in mango orchards. Phalsa leaf extract has antibacterial activity against Escherichia coli and Staphylococcus aureus. Phalsa fruit has a short shelf life, suitable only for local marketing. It is cultivated on a commercial scale, mainly in the northern and western states of India.

Introduction

Reproduction is the biological process that results in the formation of new progeny or individual organisms. Male and female gametes unite to form a zygote, which develops or produces offspring.

Introduction

It can be grown as a mixed crop in most of the orchards, as a hedge plant or as a pure crop. monocotyledonous, monocarpic, xerophytic, CAM, herbaceous perennial herb. It is drought-tolerant and suitable for marginal lands. Pineapple does not contain starch. Pineapple is a Spanish word, botanically it is called syncarpous (Sorosis) fruit. Brazilian Pineapple, Ananas microstachys is considered to ancestor of cultivated (A. comosuss). The pineapple is a tropical fruit and is known as the “Golden Queen” all over the globe. It can be grown as a mixed crop in most of the orchards, as a hedge plant or as a pure crop. Fruits are relished as dessert in the form of slices, either fresh or canned, juice, squash, jam and mixed jam. Candy is prepared from fruit cores.

Introduction

In India, pistachio cultivation is mainly grown for its edible nuts and it is a deciduous tree in the family Anacardiaceae. On the tree, pistachios grow in grape-like clusters, and the shell has the pistachio inside. The leaves of the pistachio tree are pinnate and composed of five individual oval leaflets. The pistachio tree flowers are small, brownish-green in colour, and lack petals. Pistachio trees can reach up to 20 feet in the wild but are generally smaller under cultivation. It is a famous dry fruit, widely loved by people in India.

Sexual plant propagationis multiplication of the plants by fussion of male and female gametes is called sexual plant propagation e. g seed and seedling plant. It is two types:

A. Sexual Propagation

B. Asexual Propagation

Plantation crops: Plantation crop are a group of commercial crops that are perennial in nature, cultivated extensively in tropical and subtropical situations that need employment of labour throughout the year and whose products are usually consumed after processing. ex. Tea, Coffee, Coconut, Rubber, Cocoa, Areca Nut, and Oil Palm.

Introduction

Plum is an important temperate fruit, which is used as a fresh fruit as well as in preserved form. It is next to the peaches in economic importance amongst the stone fruits. It requires a certain period of chilling during winters to break dormancy, so it is cultivated in areas where winters are cool. Fruits are a rich source of minerals, vitamins, sugars and organic acids, in addition to protein, fat and carbohydrates. The types of plums with high sugar content above 18% are known as prunes which can be dried with pit. In India, plum was introduced by Alexander Coutts in 1870 in Himachal Pradesh. After evaluation, only Japanese plum has been recommended for commercial cultivation in the mid hills of the temperate region of the north-western Himalayas. Some low-chilling varieties of plum were also introduced at Punjab Agriculture University, Ludhiana.

Introduction

Winter hardy and highly drought tolerant. This is an excellent choice crop for the arid and semi-arid conditions of India. Maharashtra is the leading state in India for pomegranate cultivation: Maharashtra. NRC of Pomegranate, Kesaon, Solapur, Maharashtra: Established in 2005. Because of the presence of anthocyanin, the aril and skin have a red color. Dried seeds with pulp are known as ‘Anardana’: It is widely used as a condiment, prepared from a sour type of wild pomegranate is called as Daru. Commonly found in the Himalayan region, has a long productive cycle and is resistant to bacterial blight. Double flower type ornamental plant in it modification of stamens into petals makes them look like rose flowers. Nana or dwarf type is called Bonsai pomegranate, exclusively used for ornamental purposes.

Pollination is a vital and key component of ecosystem services which is provided by pollinators. FAO, 2007 reported that 80 per cent of plant species rely for pollination on pollinators, which is dominated by insects. Among the insect pollinators, solitary and social bees dominate both managed and natural ecosystems. No other groups of insects are more beneficial to humans than bees. Many plants have evolved intricate relationships with many insect pollinators and without their presence, majority of plant species would not reproduce and maintain their genetic diversity (Daily et al., 1997). In natural ecosystem, insect pollination plays a pivotal role to maintain and conserve the plant biodiversity. On a global scale, the total annual value of insect pollination services has been estimated at USD 217 billion (Sciencedaily, 2008). United Nations reported that the economics of ecosystems and biodiversity by insect pollination was valued at £134 billion.
