Describe the method of artificial hybridisation

Explanation

In artificial hybridisation only the desired pollen grains are used. This is achieved by emasculation and bagging techniques. If the female parent bears bisexual flowers, removal of anthers from the flower bud before the anther dehisces using a pair of forceps is necessary. This tep is referred to as emasculation. Emasculated flowers have to be convered with a bag of suitable size, generally made up of butter paper to prevent contamination of its stigma iwht unwanted pollen. This process is called bagging. When the stigma of bagged flower attains receptivity mature pollen grain collected from anthers of the male parent are dusted on the stigma and the flowers are rebagged and the fruits allowed to develop. If the female parent produces unisexual flowers, there is no need for emasculation. The female flower buds are begged before the flowers open. When the stigma becomes receptive, pollination is carried out using the desired pollen and the flower rebagged. This is one of the major approaches of crop improvement programme
