摘要: 按格子方法对新引进美国高梁不育系 Tx622A、Tx623A、Tx624A 等进行了主要农艺性状的配合力分析。不育系间穗粒重、穗粒数、生育期、株高、穗长、角质含量配合力差异显著,千粒重配合力差异不显著。在全部被研究性状的遗传控制中,加性基因效应占主导。除 Tx622A 外,其余新引不育系穗粒重,穗粒数的一般配合力效应优于3197A,全部

Abstract: Combining ability of seven agronomic characters was estimated inthe newly introduced A-lines of sorghum from Texas of U.S.A.,including Tx622A,Tx623A,Tx624A and MartinA in partial diallel crosswith 5 R-lines as male parents,and the combination of 3197A as thecontrol.Observation was on the characters
