摘要
利用朱军等提出的遗传模型,采用3×3NCⅡ正反交设计的亲本和部分组合F2代种子,分析了糙米率、垩白粒率、垩白面积和AC间及上述品质性状与株高、穗部性状等的遗传相关,以期为粳稻育种后代选择提供指导。结果表明,精米重与糙米率存在极显著的母体加性相关;虽然控制品质性状的主要遗传效应分量与农艺性状相应遗传效应分量遗传协方差不显著,但在其他相应遗传效应分量方面存在着复杂的关系。
Genetic correlations among brown rice rate, chalkiness grain rate, chalkiness area and AC, and correlations between these quality traits and plant height and panicle trait were analyzed using parental seeds of 3×3 NCⅡ reciprocal mating and some F2 generation seeds by the genetic model given by Zhu Jun for the selection of japonica breeding progeny. The results showed that milled rice weight and brown rice rate are highly significant correlation with maternal additive effect. The genetic covariance between genetic effect components of quality traits and agronomy traits was not significant but that between quality and other plant traits was complicated.
