Abstract
[Objective]To analyze the combining ability of yield-related traits on parents of hybrid rice.[Method]The combining ability of yield-related traits was synthetically studied based on NCⅡ mating design by using 5 indica CMS lines and 5 restorer lines.[Result]Heredity of F1yield related traits were controlled by additive effect and non-additive effect.For yield per plant,general combining ability of indica CMS lines from big to small was in the order of 301A, 421A, 606A,Wufeng A, Gong A.General combining ability of restorer lines from big to small was in the order of R208, R615, Yugui, Huazhan, R319.The narrow heritability from big to small was in the order of 1 000-grain weight,length of spike neck,ear length,total grains per ear,filled grain per ear,flag leaf length,effective ear per plant,plant height,seed-setting rate, duration from sowing to heading.[Conclusion]This research provided theoretical basis for the rational utilization of parent material.关键词
