While planning fo A. Bagging of female flower

B. Dusting of pollen on stigma

C. Emasculation

D. Collection of pollen

Answer :

Artificial hybridisation programme is an approache of crop improvement. In this it is important to make sure that only the desired pollen grains are used for pollination and the stigma is protected from contamination (that is stigma is protected from unwanted pollen). This is usually done by emasculation and bagging techniques.

Emasculation is removal of anther from the flower bud. Now the left out stigma is covered with butter paper bag to prevent contamination.

Now we know dioecious plants have unisexual flowers, hence there is no need of emasculation. Instead the female flowers are directly bagged to prevent contamination. And the rest steps are carried normally.

Therefore, the correct answer is option (c).
