摘要
本文以23个春大豆品种(系)为材料,进行了春播和秋播试验。分别估算了春大豆品种×播季互作效应;春播与秋播条件下品种间主要农艺性状的遗传变异系数、遗传力、遗传进度;以及秋播农艺性状与春播单株生产力的相关等。结果表明:春大豆主要农艺性状的品种间、播季间、品种×播季互作效应存在极显著差异。百粒重、株高等农艺性状秋播遗传力较高,秋播变异率较小,遗传进度大,秋播下性状与春播下单株产量相关密切,表明秋播条件下按百粒重和株高等对单株生产力进行间接选择,其效果高于对单株生产力的直接选择,认为春播秋播下两次选择,有助于加快春大豆育种进度。
Twenty three genetically stable spring soybean ( Glycine max (L. ) Merr. ) varieties were used to study the effect of autumn sowing on the spring soybean. The variety X sowing season interaction, as well as the coefficient of genetic variation, heritability, genetic advances and the coefficient of correlation among the agronomic characters of spring soybean sowed in autumn and single plant productivity of spring soybean sowed in spring, was evaluated. The results indicated that the difference of primary agronomic characters, the diffrenee between sowing season and the variety and sowing season interaction were significant or highly significent. The effectiveness of direct selection to agronomic character of spring soybean sowed in autumn were lower. But the heritability of the 1 00-seed weight, plant height sowed in autumn were higher. The correlations between single plant productivity sown in spring and autumn sown traits exhibited highly signifi-casnt. The effectiveness of indirect selection on them might be highly effective.
