प्रश्न
While planning for an artificial hybridization programme involving dioecious plants, which of the following steps would not be relevant?
पर्याय
Emasculation
Collection of pollen
Dusting of pollen on stigma
Bagging of female flower

उत्तर
Emasculation
Explanation:
Emasculation is not needed in dioecious plants because male and female flowers are on separate plants, so there is no risk of self-pollination. Only bagging of the female flower, collecting pollen from the male plant, and dusting pollen on the stigma are necessary steps.
