摘要 以16个水稻两用核不育系(4WSH0058、4WSH0247、4WSH0266、4WSH0268、4WSH0284、4WSH0886、4WSH0887、4WSH1108、4WSH1142、4WSH1324、4WSH1334、4WSH1339、4WSH1355、4WSH1357、4WSH1369、4WSH1555)和5个恢复系(R1998、R091、R184、华占、R412)按不完全双列杂交设计配制的80个组合为材料,研究稻米外观品质和蒸煮品质性状的配合力。研究结果表明:粒长、粒宽和长宽比等粒形性状主要受基因加性效应的影响;垩白粒率受加性效应和非加性效应的共同控制,主要受恢复系基因加性效应的影响;垩白度和胶稠度主要受非加性效应的影响;稻米直链淀粉含量受不育系基因加性效应及非加性效应的共同控制,其中受不育系基因加性效应的影响较大。不育系4WSH0247、4WSH0886、4WSH0887、4WSH1324、4WSH1339、4WSH1355和恢复系R184和R412在垩白性状和蒸煮品质上具有较好的一般配合力和较大的特殊配合力效应方差,容易配出外观品质和蒸煮品质俱佳的杂交组合。 The 80 hybrid rice combinations crossed by 16 dual-purpose genic male sterile lines and 5 restorer lines obtained using incomplete diallel design were used in this study to investigate the combining ability for appearance quality and cooking quality.The results showed that the length,the width and the length/width of grain were mainly controlled by additive gene effect.The chalkiness grain rate were controlled by both additive and non-additive effects,and the additive effect of restorer lines was more important.The chalkiness degree and gel consistency were controlled by non-additive effects.Amylose content was controlled by both additive and non-additive effects,and the additive effect of sterile lines was more important.Sterile lines 4WSH0247,4WSH0886,4WSH0887,4WSH1324,4WSH1339,4WSH1355 and restorer lines R184,R412 had good general combining ability and great variance of specific combining ability regarding to chalkiness and cooking quality traits,which made it easier to obtain combinations of good appearance quality and cooking quality.
