Why is it necessary to emasculate a bisexual flower in a plant4 breeding programme ?
Answers
Emasculation is the process of removing pollen grains from the flowers. ... Pollen grains from the dehisced anthers of the desired male plant are then shed on the stigma of female flowers. This process is called cross pollination. After, the successful fertilization of male and female gametes, hybrid seeds are obtained.
Answer:
Explanation:
Emasculation is the process of removing anthers from bisexual flowers without affecting the female reproductive part (pistil), which is used in various plant hybridization techniques.
Emasculation is performed by plant breeders in bisexual flowers to obtain the desired variety of a plant by crossing a particular plant with the desired pollen grain. To remove the anthers, the flowers are covered with a bag before they open. This ensures that the flower is pollinated by pollen grains obtained from desirable varieties only. Later, the mature, viable, and stored pollen grains are dusted on the bagged stigma by breeders to allow artificial pollination to take place and obtain the desired plant variety.
Emasculation is not performed in unisexual flowers and those plants which exhibit self-compatibility.
