Ppt on Breeding methods for vegetables

Posted on by admin

Summary

The cultivation of vegetable crops involves various selection methods to improve introduced species such as potatoes, tomatoes, and capsicum. Asexual propagation through clonal selection is common, producing cultivars like Kufri Red potato and Black Beauty brinjal. Self-pollinated crops utilize pure line and single plant selection to stabilize superior genotypes, exemplified by cultivars like CO-1 tomato and Pusa Makhmali okra. Cross-pollinated crops benefit from systematic selection methods, including mass selection and line breeding, to enhance populations, leading to new cultivars like onion and cauliflower. Recurrent selection focuses on concentrating favorable genes, while hybridization generates genetic variability for improved traits. The development of hybrid varieties involves selecting parents, testing their combining ability, and producing F1 hybrids through methods like emasculation and hand

Ppt on CROP IMPROVEMENT IN ONION (Allium cepa L.)

Posted on by admin
Summary:

Discover the world of onions, their cultivation, nutritional value, and significance in agriculture with this informative PowerPoint on crop improvement in onions (Allium cepa L.). Explore the different onion types, cultivation requirements, major producing countries, and more. Perfect for anyone interested in enhancing their knowledge of onion farming and its impact on the global market.

Summary

Onions, scientifically known as Allium cepa, belong to the Alliaceae family and originated in Asia. They are a biennial herb characterized by tubular leaves and bulbs formed from swollen leaf bases attached to the underground stem. Major onion-producing countries include China, India, and Pakistan, with India ranking third in exports, primarily from Maharashtra and Karnataka. Onions thrive in a variety of climates but require specific conditions for optimal growth, including well-drained soil and adequate pollination, primarily by insects. Cultivation highlights include the development of various onion types based on color, such as yellow, red, and white, each serving different culinary purposes. Onions are rich in nutrients, providing energy, carbohydrates, and vitamins. They are significant in agriculture for their high yield

Ppt on Litchi Breeding

Posted on by admin

Summary

Litchi, originating from China where it has been cultivated for over 2200 years, has a narrow genetic base in India with only 7-8 commercially popular cultivars out of nearly 40 reported. The climatic variations can significantly affect yield, making the selection of the right variety crucial for specific regions. The litchi inflorescence consists of branched panicles with varying flower types, and the flowering period is influenced by environmental conditions. Desirable cultivar characteristics include large fruit size, good post-harvest quality, uniform ripening, and resistance to pests and diseases. Major litchi varieties include Early Seedless, Muzaffarpur, Rose Scented, Bombai, Calcutta, Late Seedless, Dehradun, Gulabi, and Swarna Roopa, each with unique traits and yield potentials. Breeding efforts focus on improving fruit quality, disease

Ppt on Fruit dropping

Posted on by admin

Summary

Fruit drop refers to the detachment of fruit from a tree or plant, caused by the formation of a separation layer of cells on the fruit stalk due to physiological or biochemical events. It can be categorized into three main periods: post bloom drops, June drops, and pre-harvest drops, with some fruits experiencing additional periods such as summer drop and summer fall drop. Post bloom drops occur shortly after flowering due to inadequate pollination, water or temperature stress, and hormonal imbalances, with gibberellic spray as a potential solution. June drops happen when fruits are 1-3 cm in diameter, often caused by water stress and competition among fruits, with solutions including regular irrigation and growth regulators. Pre-harvest drops occur after fruits
