Question

In crop improvement programmes, virus-free
clones can be obtained through
(a) grafting (b) hybridization
(c) embryo (d) shoot apex culture

Answer 1

option C

Embryo culture. 14%

Grafting. 16%

Shoot apex culture. 39%

Hybridisation. 31%

Answer 2

Crop improvement program:

• Option “D” is correct i.e. shoot apex culture.

• In the crop improvement program, the virus-free clones can be obtained through shoot apex culture.

• Tissue culture method can be employed for the production of vims-free plants one or the other by meristem culture chemotherapy or selective chemotherapy of larger explants from donor plants. Shoot apex involves of meristematic cells, thus, shoot apex culture is effective to obtain virus-free clones in crop development programs
