Emasculation is a process used in plant breeding to obtain a desired variety of a plant by crossing a particular plant with the desired pollen grain. It is performed in bisexual flowers to prevent self-pollination and is useful in artificial hybridization, where the desired pollen is required. The process involves removing the stamens from a bisexual flower before they shed pollen. This ensures that the flower is pollinated by pollen grains obtained from desirable varieties only. Emasculation is performed by plant breeders in bisexual flowers to get the specified form of a plant by crossing a specific plant with the specified pollen grain. The process is performed by covering the flowers with a bag before they open to remove the anthers. This makes sure that the flower is pollinated by pollen grains obtained from desirable varieties only.
