Question

Marker-assisted backcross breeding (MABB) is a systematic approach to transferring a gene from a donor genotype to a recipient variety of crops. Arrange the activities serially i.e. performed first to the last:
(A). Production of \( F_1 \) hybrids through hybridization between the donor and the recipient genotypes
(B). Foreground and background selection and backcrossing (or selfing)
(C). Hybridity testing and backcrossing with the recipient variety
(D). Selection of donor and the recipient variety based on target gene
Choose the correct answer from the options given below:

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

Hint:

To solve any backcrossing sequence question:
First: Select parents based on the target gene (D).
Second: Make the initial \( F_1 \) cross (A).
Third: Test the hybridity of the \( F_1 \) plants before backcrossing (C).

Answer 1
