Question

Which of the following step is the main root of any plant breeding programme?

• A. Genetic variability
• B. Evaluation and selection of parents
• C. Cross hybridisation among the selected parents
• D. Selection and testing of superior recombinants

Answer 1

Answer:

A. Genetic variability

• Genetic variability is the root of any breeding programme.

• In many crops, pre-existing genetic variability is available from wild relatives of the crop.

• Collection and preservation of all the different wild varieties, species and relatives of the cultivated species is a pre-requisite for effective exploitation of natural genes available in the population.
