Emasculation is removal of stamens of plant to prevent self pollination. It is not required in a plant that has female parent produces unisexual flowers and the plant that has no flowers.

Emasculation is concerned with
1 Clonal selection
2 Hybridization
3 Pure line selection
4 Mass selection
Explanation:
Emasculation is defined as removal of anthers from the flower before maturity to avoid self pollination and to favour cross pollination. Emasculation is an essential step in the process of hybridization. Done if female parent plant is having bisexual flowers.

The necessity of bagging is
1 To avoid contamination of stigma with unwanted pollen
2 To avoid self pollination
3 Both (1) and (2)
4 None of these
Explanation:
Bagging is done for the emasculated flowers to prevent contamination of its stigma with undesired pollen grains.

While planning for an artificial hybridization programme involving dioecious plants, which of the following steps would not be relevant?
1 Bagging of female flower
2 Dusting of pollen on stigma
3 Emasculation
4 Collection of pollen
Explanation:
Artificial hybridization is one of the major approaches of crop improvement programme. In such crossing experiments it is important to make sure that only the desired pollen grains are used for pollination and the stigma is protected from contamination. This is achieved by emasculation and bagging techniques. Emasculation is relevant in bisexual plants.
