Other claims from this paper (11)
- Observation Wheat genotypes differed significantly for all studied traits except spike number per plant under stress.
- Observation General and specific combining ability mean squares were highly significant for all studied wheat traits.
- Association General combining ability mean squares exceeded specific combining ability mean squares, suggesting predominant additive genetic effects.
- Observation Additive and dominance genetic components were highly significant under stress for all traits.
- Observation Dominance gene action was significant for all studied characters except heading and maturity dates.
- Association The dominance component exceeded the additive component and indicated overdominance for the stated characters.
- Observation H2/4 H1 deviated from 0.25 for the other wheat traits.
- Observation Broad-sense heritability estimates were high.
- Observation Narrow-sense heritability for heading date was high to moderate.
- Recommendation The authors suggest that selection could be useful given additive genetic variance.
- Observation Narrow-sense heritability was also reported as low for all traits, implying nonadditive variance.
