以5个不育系和5个恢复系为材料，采用不完全双列杂交设计研究水稻25个主要品质性状配合力和遗传力的表现规律。结果表明：米质性状一般配合力差异达显著或极显著水平，一般配合力基因型方差占遗传总方差的比重显著大于特殊配合力占遗传总方差的比重；粒长、垩白粒率、垩白度、碱消值和胶稠度等受不育系影响较大，糙米率、精米率、整精米率和直链淀粉受恢复系影响较大；各性状狭义遗传力大小顺序为：垩白粒率＞垩白度＞粒长＞整精米率＞碱消值＞直链淀粉含量＞精米率＞糙米率＞胶稠度；亲本 EF14A 和福恢2108在改良组合米质方面有一定的利用价值。

Five sterile and 5 restoring lines of Indica rice were selected to study their combining abilities and heritabilities on 25 quality traits using an incomplete diallele cross design.The results showed that (a)the combining abilities of all selected traits differed significantly,and the ratio of genotypic variance to the entire genotypic variance of the general combining ability was significantly higher than that of the specific combining ability;(b)the grain length,percentage of chalky grain,chalkiness degree,alkali spreading value and gel consistency were affected mainly by the sterile line,while the brown rice percentage,milled rice rate,head rice yield and amylase by the restorer line;(c)the narrow heritability of the traits were in the order of:percentage of chalky grain,chalkiness degree,grain length,milled rice rate,amylase,alkali spreading value,head rice yield,brown rice percentage and gel consistency;and,(d)EF14 A and Fuhui 77 could potentially be used as parents for breeding hybrid rice.
