Question

Regarding assertion and reason, choose the correct option
Assertion [A] : Emasculation and bagging are essential in artificial hybridisation
Reason [R] : Both the steps are essential to avoid contamination from unwanted pollen

• A. Both A and R are true and R explains A
• B. Both A and R are true but R does not explain A
• C. A is true and R is false
• D. Both A and R are false

Answer 1

The correct option is A Both A and R are true and R explains A

Artificial hybridisation is the production of hybrids by cross-pollinating two separate plants under controlled conditions, often under the supervision of a plant breeder. Emasculation is the process of removing anthers from bisexual flowers without affecting the female reproductive part (pistil). This is done to use the pollen grains from the desired male parent for fertilisation. After emasculation, the stigma is covered with bags made of butter paper to prevent contamination from unwanted pollen. Both emasculation and bagging ensure that only the chosen male and female parents are participating in the hybridisation.
