Study Notes
Major Problems in Fruit Breeding
- Fruit crops have long generation cycles (2-10 years) and juvenile periods, making early assessment difficult
- Fruit species are highly heterozygous, requiring large populations for effective selection
- Many fruit species are polyploidy (e.g. ber, banana) and exhibit polyembryony (e.g. citrus, mango)
- Some fruit species exhibit parthenocarpy and seedlessness (e.g. banana, pineapple) and sexual incompatibility (e.g. mango, apple, pear, loquat)
- High number of chromosomes hinders genetic analysis (e.g. ber, mulberry)
- Excessive fruit drop is a problem in some fruit crops (e.g. mango, citrus, grape)
- Presence of single seed in many fruit species requires more crosses (e.g. mango, litchi, mahua)
Objectives of Plant/Fruit Breeding
- The main objective is to achieve maximum quality production per unit area with low cost and minimal biotic and abiotic stresses
- Objectives vary depending on the fruit plant, location, and requirements
Importance of Fruit Breeding
- Fruit breeding research in India began in the twenties and gained importance in the sixties due to growing awareness of fruits' importance in daily diet
- During the last two decades, research approach on fruits has undergone significant changes with increased multi-location, interdisciplinary, and inter-institutional involvement
- Intensive research has resulted in the development of improved cultivars, but problems in breeding horticultural crops still exist
- There is a need for systematic and dedicated efforts to develop ideal varieties through modern tools in fruit crops
Definition of Fruit Breeding
- Fruit breeding is the manipulation of a biological system that requires many generations to achieve results
- It is a dynamic, exciting, and challenging profession that operates under continually changing conditions
- Fruit breeding involves the genetic improvement of crop plants for economic use and is an art, science, and technology
- The aim of plant breeding is to improve the characteristics of plants to make them more desirable agronomically and economically
