Q- What is hybridisation? How is it advantageous in crop improvement?
Answer- Hybridisation is the process of crossing of two plants differing from each other genotypically in one or more traits.
Hybridisation is one of the moist advantageous source or method to improve crop variety not only in crop this method is also used in animals to improve their breed as well as production. In hybridization the crossing may be intervarietal (this means between different varieties), interspecific (interspecific means between different species of same genus) or intergeneric (intergeneric means between different genera).
There are three main objectives of hybridisation:
1. To produce a single variety having combination of good characters.
2. To increase as well as generate variations through recombination.
3. To exploit as well as utilize the hybrid vigour.
According to question, the main advantages of hybridisation are as follows:
1. The improved hybrid variety is vigorous in growth.
2. The hybrid has more disease resisting power.
3. The hybrid provides more production as compared to parent.
4. Hybrid has dominant characters of both parental bodies.
