| 摘 要： | 在二棱大麦中赤霉病抗性很强的Ｒｕｓｓｉａ６号和六棱大麦中抗性很弱的ＨＥＳ４的杂交后代Ｆ２代的５６０个个体中，以随机抽出８０个个体所展开的Ｆ３—Ｆ５系统来分析赤霉病抗性的亲子相关．结果表明，随着世代的推进，系统内标准差逐渐变小，相关系数逐渐提高，到Ｆ５抗性分离逐渐稳定，Ｆ４个体和由这个个体所展开的Ｆ５系统平均值之间的相关系数为０．６７０，Ｆ４个体所在的系统平均值和Ｆ５系统的平均值之间的相关系数为０．７９０，系统之间的相关系数大于亲代个体和次代系统平均值之间的相关系数．

| Abstract: | In 560 hybrids from Russia-6 which the resistance was high in two-rowed barley and HES4 Which had low resistance in six-rowed barley. 80 individuals were sampled at random to analyse the parent-offspring correlation of resistance to Gibberellic disease. The result showed, with the generation advanced, the standard deviation became small, correlated coefficient increased. To F5 generation, it was gradually stable. The correlated coefficient of F4 and average value of F5 system was 0.670, it was 0.790 about average value of F4,F5 systems. The correlated coefficient of individual was higher than that of average value of system. |
