以黑龙江省13个育种单位覆盖6个积温带的132份品种为试验材料,采用灰色关联分析方法,对影响大豆单株粒重的主要农艺性状进行了分析。结果表明在与大豆单株粒重相关的农艺性状中,荚粒重、单株粒数和3粒荚数的重要性排在了前三位,整体性状重要性的排序为:荚粒重>单株粒数>3粒荚数>2粒荚数>茎杆重>4粒荚数>荚皮厚>1粒荚数>粒宽>主茎节数>百粒重>株高>2粒荚宽>粒长>2粒荚长>结荚高度。本文利用大量品种明确了大豆主要农艺性状对产量的贡献,为大豆高产育种提供了参考依据。
132 varieties covered by 6 accumulated temperate zones in 13 breeding units in Heilongjiang Province were used as experimental materials, and the main agronomic traits affecting the grain weight of soybean were analyzed by gray relational analysis. The results showed that in the agronomic traits associated with grain weight per plant, the order of pod weight, plant grain number and pod number was in the top three. The importance of the whole traits was ranked as follows: pod weight> Number of pods> 3 pods> 2 pods> stalk weight> 4 pods> pod thickness> 1 pod number> grain width> number of main stems> 100-grain weight> plant height> 2 grains Pod width> grain length> 2 pods> pod height. In this paper, a large number of cultivars were used to clarify the contribution of the main agronomic traits of soybean to the yield and provide a reference for the high-yield breeding of soybean.
