The genetic variations of 7 quality characteristic evaluated were significant. Both additive and dominance effects were important for all-7 quality characteristics. Furthermore, additive effects were significantly larger than dominance effects for all quality characteristics evaluated except for gel consistence. Estimated heritabilities for all characteristics were very high, indicating that a major portion of phenotypic variability was controlled by additive effects. Maternal effects existed in alkali spreading score, amylose content, gel consistence, kernel width and kernel thickness. |
