Selection Methods, Breeding Schemes
- Recurrent Selection for Specific Combining Ability (Hull, 1945):
- Designed specifically to exploit non-additive genetic variance (overdominance and epistasis).
- Methodology: A heterozygous, genetically segregating foundation population is test-crossed to a constant, homozygous inbred tester line (typically using inbred males / sires as the common tester).
- Selected individuals from the segregating population are intermated in purebred lines based on their crossbred progeny performance with the inbred tester line.
Correct option: (1) Inbred male
