Question

It is a major approach of crop improvement programme. In such crossing experiment it is important to make sure that only the desired pollen grains are used for pollination and the stigma is protected from contamination. How can it be achieved?

Answer 1

Explanation:

*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 contamination (from unwanted pollen).

HOPE IT WOULD BE HELPFUL

Answer 2

Answer:

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 contamination (from unwanted pollen). This is achieved by emasculation and bagging techniques.

The process of hybridization involved following steps:

i) Choice of the Parents:

ii) Evaluation of the parents,

iii) Selfing of parents,

iv) Emasculation,

v) Bagging

vi) Tagging

vii) Pollination

viii) Harvesting

ix) Threshing, drying and storage
