摘　　要：以50个大麦品种(系)为试材,用 kempthorne 部分双列杂交法分析各生育期性状和单株产量。结果表明广义遗传力由大到小是成熟期、灌浆期、孕穗期、出苗期、抽穗期、单株产量。各品种(系)间的5个生育期和单株产量性状的一般配合力差异显著。Circulant plans For diallel crosses introduced by O.Kempthrone & R.N.Curnow were used to study seeding,booting,heading,grain filling and maturing stages and kernel weight per plant in barley.According to their numerical values of heritability,the characters stu- died were arranged in thc sequence of maturing stage,grain filling stage,booting stage, seeding stage,heading stage,kernel weight per plant.General combining ability of 6 char- acters of 50 varieties were tabulated
