Artificial hybridisation is one of the major approaches of crop improvement programme. For the bisexual flower it includes the following steps in correct sequence.

Options

A. Bagging, pollination, rebagging
B. Pollination, bagging, rebagging
C. Emasculation, bagging, pollination, rebagging
D. Bagging, emasculation, pollination, rebagging

Answer

C

Explanation

• A breeder is interested in crossing different species and often genera to combine desirable characters to produce commercially .superior varieties.
• Artificial hybridisation 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 contami nation (from unwanted pollen). This is achieved by emasculation and bagging techniques.
• If the female parent bears bisexual flowers, removal of anthers referred to as emasculation. Emasculated flowers covered with a bag of suitable size, gener ally made up of butter paper to prevent contamination of its stigma with unwanted pollen. This process is called bagging. Pollen grains collected from anthers of the male are dusted on the stigma, and the flowers are rebagged, and the fruits allowed to develop.
