State what is apomixis. Comment on its significance. How can it be commercially used?

Solution

Apomixis is a form of asexual reproduction in which seeds are formed without fertilisation. It is a form of asexual reproduction that mimics sexual reproduction.

Significance:
Apomixis allows certain species of plants belonging to Asteraceae, and grasses to produce seeds which do not produce seeds by the process of fertilisation.

Commercial applications of apomixis:
1. Hybrid varieties of seeds can be produced in lesser time, which provide higher and better yield.
2. It prevents the loss of specific characteristics in the hybrid plants.
3. Apomixis is a cost-effective method of producing seeds.
