Study Notes
Major Problems in Fruit Breeding
- Fruit crops have a long generation cycle, ranging from 2-10 years, depending on the species and cultivars.
- Most fruit crops have a long juvenile period, making it difficult to assess strains early.
- Fruit species are highly heterozygous, requiring large populations for effective selection.
- Many fruit species are polyploid in nature.
- Polyembryony is a characteristic of some fruit species, such as citrus and mango.
- Some fruit species exhibit parthenocarpy and seedlessness.
- Sexual incompatibility is a problem in some fruit species.
- A large number of chromosomes in some fruit species hinders genetic analysis.
- Excessive fruit drop is a common issue in fruit crops.
- Single-seed fruits require more crosses.
Objectives of Plant/Fruit Breeding
- The primary objective of fruit breeding is to achieve maximum quality production per unit area with low cost and minimal biotic and abiotic stresses.
- Higher yield is a key objective, achievable through evolving high-yielding varieties or hybrids.
- Improved quality of produce/fruit is another important objective.
- Fruit breeding aims to develop varieties resistant to abiotic factors such as drought, soil salinity, and extreme temperatures.
- Developing varieties resistant to biotic factors such as diseases and insects is also an objective.
- Changing the maturity duration or earliness is desirable, as it has several advantages.
- Desirable agronomic characteristics, such as plant height and branching, are also important objectives.
- Eliminating toxic substances from crops to make them safe for human consumption is an objective.
- Synchronous maturity is a desired trait 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 can be defined as an art, a science, and technology of improving the genetic makeup of plants for their economic use.
Aim of Plant Breeding
- The aim of plant breeding is to improve the characteristics of plants, making them more desirable agronomically and economically.
