本文采用“基因型分组法”及“稳定性参数法”对1982年种植在牡丹江地区的六个不同地点的四个大豆新品种和一个对照品种进行了稳定性分析,并对稳定性与大豆七个主要农艺性状的相关性进行了初步探讨。结果表明:用这两种方法进行稳定性分析,结论基本吻合。有二个品种较对照品种为稳定,另两个则不如对照。但两种方法各具特色。“基因型分组法”较为简便易行,尤其适用于测定大群体的试验材料;而“稳定性参数法”则较为科学准确。在与主要农艺性状相关性研究中,只有百粒重与品种的稳定性呈正相关,其余性状如成熟期,生育日数、主茎节数、分枝数、株荚数、株粒数等均与稳定性呈负相关。相关程度达到显著水平的性状有生育日数、成熟期。
In this paper, the genotyping method and stability parameter method were used to analyze the stability of four new soybean cultivars and one control cultivated in six different locations in 1982 in Mudanjiang, The main agronomic traits related to a preliminary study. The results show that the stability analysis by these two methods is basically consistent. Two varieties are more stable than the control varieties, the other two are not as good as the control. But the two methods are different. The “genotyping method” is relatively simple and convenient, especially suitable for the determination of large groups of test materials; and “stability parameter method” is more scientific and accurate. In the study of the correlation with major agronomic traits, only the grain weight was positively correlated with the stability of varieties, and the rest of the characters such as maturity, number of days of birth, number of main stems, number of branches, number of pods, Stability was negatively correlated. Related to reach a significant level of traits have days of fertility, maturity.
