本文所研究的总体为江淮下游大豆地方品种群体,供试材料为78个品种组成的随机样本。所研究的17个农艺性状归成产量、产量因素、形态数量以及生育期等四组,产量与产量因素的典型相关高于与形态数量性状的相关,又高于与生育期性状的相关。产量因素与形态数量性状间的典型相关高于形态数量性状与生育性状间的,又高于产量因素与生育期性状间的相关。逐步回归及偏回归分析结果,产量因素间的相关与习惯上将大豆品种分为大粒型及多荚型相一致。对各组间及组内性状间的偏相关及遗传型简单相关结果也作了讨论。
The population of soybean cultivars in the lower reaches of JAC was studied in this paper. The random sample of 78 cultivars was used as test material. The 17 agronomic traits studied were grouped into four groups: yield, yield, morphological number and growth period. The typical correlations between yield and yield were higher than those related to morphological traits and higher than those related to growth traits. The typical correlation between yield factors and morphological quantitative traits was higher than that between morphological quantitative traits and fertility traits and higher than the correlation between yield factors and growth traits. Stepwise regression and partial regression analysis results, the correlation between yield factors and habits will be divided into large-grain soybean varieties and multi-pod consistent. The partial correlation between the groups and the traits in the group and the simple correlation results of the genetic type were also discussed.
