Mode of reproduction
- Knowledge of the mode of reproduction and pollination is essential for a plant breeder, because these aspects help in deciding the breeding procedures to be used for the genetic improvement of a crop species.
- Choice of breeding procedure depends on the mode of reproduction and pollination of a crop species.Reproduction refers to the process by which living organisms give rise to the offspring of similar kind (species).
- In crop plants, the mode of reproduction is of two types: viz.
- sexual reproduction and
- asexual reproduction
- In the sexually reproducing crop plants, definite male and female sexual organs namely androecium and gynoecium produce male gametes and female gametes respectively. The male gametes are formed from a haploid cell called microspore and the female gametes are formed from a haploid cell, megaspore.
