Other claims from this paper (8)
- Association Epistasis significantly affected grain yield and accounted for 21 of generation-mean variation.
- Association Epistasis significantly affected grain moisture and accounted for 18% of generation-mean variation.
- Observation genetic variance for grain yield ranked F2-Syn8 > F2 > BCP1 > BCP2 without significant differences.
- Observation heritability for grain yield ranked F2-Syn8 > F2 > BCP1 > BCP2 without significant differences.
- Observation Predicted gains ranked in agreement with heritability.
- Observation At low selection intensity, predicted mean (usefulness) followed the reported generation ranking.
- Observation At high selection intensity, usefulness followed the reported generation ranking.
- Recommendation Random mating F2 before selection and inbreeding offers little to no advantage.
