Why emasculation is needed in Mendel's technique of hybridisation of plant?

Dear student,

Emasculation is a process of removal of male reproductive organs that is stamen which produces pollen grains from the flower before it achieves maturity. It is done in the flower which is selected as the female parent because after emasculation only female reproductive part of the flower will remain in it. Moreover emasculation promotes cross pollination rather than self pollination. That is why emasculation is needed in Mendel's technique of hybridisation of plants.

 Thanks and regards.
