This book is designed to serve as a handy guide for students, teachers, researchers, and amateurs engaged in Fruit Science. It will serve as a guide to the students and teachers to test their knowledge in the field of fruit science as a whole.

Fruit research in India was started in the department of Botany in six-agriculture College in 1905. A pomological station was established at Coonoor, Ooty in 1920 to study the adaptability of temperate fruit varieties. Four Regional Research Station in - 1933 Subtropical location at Sabour, Bihar Koduru, Madras Krishnanagar, Bengal Temperate Region at Chaubatia, Uttarakhand The research was also initiated in 1945 in Jammu and Kashmir by the Survey of deciduous fruits In 1950, Horticulture Research Station was established at Kandaghat and Kullu

Agriculture - 26% GDP, Processed food industry - 6.3% GDP. Simple fruits: Fruits which develop from a single ovary of a single flower e.g., Lemons, citrus, peach, apple, pear etc. Aggregate fruits: Fruits which develop from many ovaries of a single flower e.g., Raspberry, strawberry, blackberries. Multiple fruits: Fruits which develop from many ovaries of many flowers e.g., Pineapple. Pre harvests spray of calcium and brown on fruits and results in improving firmness. Worldwide postharvest fruits and vegetable losses are as high as 25-40.

Introduction, importance and scope of Canopy management The tatura trellis uses more water than other systems. Light interception ranges from 57 to 81% of available light. HDP increases light interception of 20% and 60%. Meadow orchard system affords more light than other conventional systems. The orientation of North to South intercept should be about - 89% of direct and 87% of diffused light. Summer priming in combination with dormant priming reduces light interceptor by 15%. In the bottom of 4m tall trees, the light is reduced to 10% of full sunlight. Light transmittance is a logarithmic function of the leaf area index. Photosynthetic Active Radiation (PAR) is from 380-720 nm. Photosynthesis to be about 60% of the maximum at 25% of full sunlight.

Breeding objectives genetic resources and techniques for breeding There are countries that consume 100 to 150 kg yearly per capita while others which do not even make it to 10kg. Genetic variability is the raw material of the plant breeder. International network for the improvement of Banana and Plantain (1 NIBAP), Prance to conserve the available germplasm. Only pathogen gene-free planting material can be used for construction or distribution from the gene bank for further multiplication or utilization in any breeding program. Fruit breeders have therefore tended to utilize single gene variants in performance to polygenic variation. In general, for most commercial requirements, homozygous is inadequate by six or seven generations of selling (56 or 37). In the dominance hypothesis, it is assumed that the deleterious gene is normally recessive. The simplest approach for the selection of our breeders is mass selection.

Introduction to Hi-Tech Horticulture Greenhouse area in different countries Japan - 42,000 (ha) Holland - 10,000 (ha) 3) Italy - 20,000 (ha) USA - 4,000 (ha) India - 700 (ha) Crops are grown in the greenhouse Strawberry, grapes, citrus, banana, papaya, melons. Salt affected soils in different states: UP - 2,375 ° Gujarat - 1,334 W.B. - 1,150 RJ - 458 Punjab - 749 Haryana - 636

Annual rainfall requirement- 75-190 cm Common names of Malda - Fazli in Calcutta Bombay green in UP Sehroli in Delhi The ‘Portuguese Jesuits in Goa started Inarching about 300 years ago. (90% success) The seedlings can be inarched when they are three months old as is done in the “Philippines”. The Indian nurserymen usually practice inarching in one-year-old seedlings. Grafts onto older seedlings result in poor root system. There should be no rain; otherwise, water gets inside the union and causes rotting of tissues. The name Mangifera was given for the first time by “Bontus” in 1658 when he referred to this as arbor Mangifera (the tree producing mango). Linnaeus also referred it as Mangifera arbor in 1747 before changing the name to its present form “Mangifera indica” in 1753. Mango was firstly grown within glasshouse in 1960 at England.

Seeds stratification at 4-7°C for 60-90 days from December to February. Scions cannot be used for grafting at their active stage of growth. Meadow orcharding: 20,000-70,000 plants/ha (Super high density) Bitter pit of apple: Golden delicious, yellow (due to calcium) Newton. Internal browning: Newton Himachal Pradesh is known as the “Apple bowl of India” Flower colour: White to Pink Apple is the most widely grown temperate fruit in the world India rank 5th in apple production in the world Apple crop accounts for 55% of the total area and 75% of the total production of temperate fruits in the country. 25% to 33% of pollinating trees in India are recommended for regular cropping. San Jose scale was introduced in India from France in 1906. Apple cider-fermented wine is prepared from apples.

It is controlled to parthenocarpy and sterility which can be achieved by triploids. Wild species - M. acuminata and M. balbisiana The cultivated edible banana is mainly triploid. The major problems in the breeding of banana are sterility, polyploidy and parthenocarpy. The underground portion of banana is a modified form of stem known as rhizome. The portion above the ground made of sheaths of leaves is known as pseudostem. Banana initiates flowering 9-12 months after planting. Sword sucker with narrow, slender leaf blades is the best planting material. Banana is a moisture and nutrient loving shallow-rooted plant. Simmonds and Shephard (1955) devised a scoring technique for genomic classification of banana. Pollination in banana is mediated mainly by bees and birds. Banana fruit follows the double sigmoid growth curve (seeded -sigmoid parthenocarpic - double sigmoid)

Citrus reticulata A highly polyembryonic species of Chinese origin Mandarin occupies 43% area and 42% under citrus spp. Seeds of citrus plants do not have dormancy so they should be sown immediately after extraction.

Flowering planting after four years. Flower bud differentiation of at 40 leaves stage. Flowering time March-April after 7 weeks of fruit development. Mealybug attacks shoots and in between the fruit segments – 0.5% phosphamidon or dichlorvos. A virus transmitted by lace bug or mealybug causes pineapple wilt. Ripon normally can be stored at 5°C for six weeks. Suckers weighing 500-750g and slips weighing 300-400g are better for yield and quality. Pineapple exhibits vegetative parthenocarpy and self-incompatibility. This is non-climacteric fruit. Sunscald discord is due to exposure of fruit to sun rays. Multiple crown/ fasciations is another important disorder probably due to genetics/nutritional factors. It contains an enzyme known as Bromelin.

Yellow pigment in papaya - Caricaxanthin The enzyme present in dried latex of papaya (papain) is pepsin. Frost is the most limiting factor for papaya cultivation in North India.

Triploidy is the cause of seedlessness in guava. Red pulp colour is dominant to white and that this character is governed monogenic gene. Guava improvement work for the first time was initiated in 1907 at Ganeshkhind Experiment Station, Pune, Maharashtra. The fact that Guava wilt is soil-borne was first reported in 1935 from Babakkarpar Allahabad. Usually, fifteen days period is required for the complete wilting but some trees take even up to one year. In general, the more than 10-year-old plants are more prone to wilt incidence. Guava wilt, effects more severely in alkaline soils. Wilting is observed during the rainy season. It starts in August with the largest number of the plant dying in September and October. Guava improvement work was started at Pune in 1907.

The chestnut is a nutritious low in fat and rich in Vitamin B. Freshly harvested nuts contain about 50% moisture, 40-42% carbohydrates, 2.9% proteins and about 1.5% fats. All cultivars of chestnut are self-sterile. The Chinese chestnut is the earliest tree to bloom. The flowers are produced in two kinds of catkins borne on current season shoot near the terminal portion of the shoot. Three nuts are usually produced in each bun (upper, left and right). Botanically, each nut is a complete fruit. The shell of the nut develops from the ovary wall. It is as hardy as peach and can withstand as low as -29°C temperature in deep dormancy. Some species of chestnut are used as rootstock for propagation. Chestnut is a highly cross-pollinated and hybrid seedling used as the rootstock is a possible cause of graft union failure in chestnut. Therefore, mixed hybrid strains should not be used as rootstock.

Turkish hazelnut production of 625,000 tons accounts for approximately 75% of world productions. The common hazel (Corylus avellana) is native to Europe and Western Asia. In H P, it is found growing wild in Pangi region of Chamba district and locally known as Thangi. Hazelnut is also known as cobnut and filbert. Hazelnuts are extensively used in confectionery to make praline and also used in combination with chocolate truffles. The temperature of minus 10°C is critical, especially if accompanied by wind, which may kill both pistillate and staminate flavours. Hazelnuts are more shallow-rooted, most fruit and nut trees do not tolerate wet soils, the tree cannot tolerate excessive dry summer heat and hot winds. Hazel will grow in pH ranging from 4.5-8.5 but around pH 7 is ideal.
