| 摘 要： | 以2个垩白粒率差异较大的粳稻品种‘莎莎妮’（垩白粒率为2.5%）和‘辽粳326’（垩白粒率为72.3%）的杂交后代F1、F2群体为试材，利用数量性状遗传分析方法，研究北方粳稻垩白粒率的遗传规律。结果表明：（1）垩白粒率的遗传受母体植株的影响较大，在F?2米粒间（着生在F1植株上的米粒）没有发生分离。（2）着生在F?2植株上的米粒的垩白粒率的变异主要是由遗传因素引起的，其遗传模型为2对加性-显性-上位性主基因+加性-显性多基因模型，低垩白表现为显性。（3）主基因遗传力h2mg（%）很大，达到了90.38%，多基因遗传力h2pg（%）只占0.11%，并且存在一对效应很大的主效基因。

| Abstract: | Inheritance of chalky rice rate of north japonica rice was studied by using quantitative character genetic analysis method,with hybrid progenies F 1,F 2 of ' Shashani '(chalky rice rate was 2.5%) and ' Liaojing 326 '(chalky rice rate was 72.3%),which had significant difference in chalky rice rate.The results showed that:(1) chalky rice rate was greatly affected by the maternal plant and no genetic segregation occurs among F 2 grains born on F 1 plant.(2) The variation of chalky rice rate among grains born o... |
