Plant breeding programmes are carried out in a systematic way. The newly selected lines produced through this methodology are evaluated for their yield and other agronomic traits. Choose the correct option for this evaluation.
1 Testing is performed in all the agroclimatic zones where crop is usually grown
2 Evaluation in farmers field is followed by testing in research field
3 Results are compared with any available local crop cultivar
4 Testing is done for minimum two growing seasons
Explanation:
Evaluation in research fields is followed by testing in farmer's fields, for at least 3 growing seasons and compared with best available local \crop cultivar

In case of plant breeding, cross hybridisation is a time consuming and tedious process because
1 To identify plants with desirable combination of characters
2 Pure lines are very rare in nature
3 Hybrids are always mutated and never recombinants
4 Variability is never seen in germplasm
Explanation:
In case of plant breeding, cross hybridisation is a time consuming and tedious process because to identify plants with desirable combination of characters. All other options are wrong.

Assertion : Removal of male parts is called emasculation. Reason : Bagging is not required for emasculated flowers.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
In case of bisexual flowers, the anthers of the proposed plant are removed before they dehisce. The process is called emasculation. The emasculated flowers are immediately covered by paper or polythene bags by the process called bagging. It prevents unwanted pollen to come in contact with emasculated flowers.

What is a pre-requisite for effective exploitation of natural genes available in the populations?
1 Collection and preservation of all the different wild varieties, species and relatives of the cultivated species
2 Collection and preservation of only the cultivated species
3 Evaluation for their characteristics
4 Both 1 and 3
Explanation:
Collection and preservation of all the different wild varieties, species and relatives of the cultivatedspecies (followed by their evaluation for their characteristics) is a prerequisite for effective exploitation of natural genes available in the populations.
