Question

The development of a synthetic variety in a cross-pollinated crop involves several activities that are performed serially one after another. Arrange the steps in chronological order i.e. from the beginning to the end:
(A). Production of the synthetic variety
(B). Collection of inbreds and testers (OPVs)
(C). Top cross or poly-cross test for GCA and selection of inbreds as parental lines
(D). Multilocation testing of the synthetic variety and distribution
Choose the correct answer from the options given below:

• A. (B), (C), (D), (A).
• B. (B), (C), (A), (D).
• C. (B), (A), (D), (C).
• D. (C), (B), (D), (A).

Hint:

In synthetic breeding, testing for General Combining Ability (GCA) is always done before the selected parental lines are mixed and intermated to produce the actual synthetic variety.
