Question

The process of removing stamens from the flower bud during hybridization is called?
A. Crossing
B. Selfing
C. Emasculation
D. Caping

Answer 1

Hint: One of the major approaches to crop improvement programs is Artificial hybridization. In the experiments in which crossing is done, it is crucial to be sure that only the desired pollen grains are taken for pollination and that the stigma is secured from contamination (from unwanted pollen ). This is achieved by some techniques. 

Complete step-by-step answer: Artificial hybridization is achieved by emasculation and bagging techniques. If the female parent has bisexual flowers, removing anthers from the flower bud before the dehiscence of the anther by using a pair of forceps is necessary. This step is called emasculation. Emasculated flowers are needed to be covered with a bag of a size suitable to the plant, mostly made up of butter paper, to prevent contamination of its stigma with unwanted pollen. This process is called bagging.
The flower attains receptivity when the stigma is bagged. mature pollen grains are taken from anthers of the male parent dusted on the stigma collected and flowers are rebadged, and the fruits are allowed to develop. 
Caping is the process of covering the flower to prevent cross-pollination. Crossing means hybridization. Selfing is also called self-pollination. It is the form of inbreeding or mating among close relatives.    

Hence the correct answer is option C.

Note: If the female parent generates unisexual flowers, there is no need for emasculation. Bagging of female flower buds is done before the opening of flowers. After the stigma is becoming receptive, pollination is done by using the desired pollen, and the flower rebags.
