While planning for an artificial hybridization program involving dioecious plants, which of the following steps would not be relevant?

Options

A. Bagging of female flower
B. Dusting of pollen on stigma
C. Emasculation
D. Collection of pollen

Answer

C

Explanation

Artificial hybridisation is one of the major methods of crop improvement programme. This cross will make sure that only the desired pollen grains are used for pollination and the stigma is protected from contamination (from unwanted pollen). This is achieved by emasculation and bagging techniques: If the female parent produces unisexual flowers there is no need for emasculation (a process of removal of anther). The female flower buds are bagged before the flowers open. When the stigma becomes receptive, pollination is carried out using the desired pollen and the flower rebagged: This protects them from contamination by unwanted pollen grains. When the female parent bears bisexual flowers removal of anthers from the flower bud before the anther dehiscence is necessary.
