【摘要】 本文叙述了孕性程度不同的大豆M₁及后代各性状的相关统计性分析结果.结果表明,可供用作M₁代生物损伤指标的植株性状与M₁代各性状间的相关关系比较复杂。M₁主要产量性状及一粒英率与M₂各性状简单相关性显著,但多元相关性显著则甚少.因此,很难以一、二个简单明确的M₁损伤指标来预测后代的突变情况,对辐射后代材料应早期开始多性状和连续性选择。更多还原

【Abstract】 This article presenes the anslytic result of statistical correlation between the soybean M₁ with various degree of fertilily and the characterso of progeny. It showed the comparative complication in correlation between the characters of major prodoct and monopode in M₁ and those in M₂, but there were no marked multiple correlation. Therefore, it is difficult to choose one or two simple and deiinited target of M₁ damage, to forecast the mutation of porgeny. The plant of irradiated progeny should come into selection of continuity and multicharacter in early period.更多还原
