黑龙江省大豆品种单株粒重与其他农艺性状的灰色关联度分析

Grey correlation degree analysis between seed weight per plant and other major agronomic traits with soybean varieties in Heilongjiang Province

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。

Total 132 soybean varieties,developed by 13 breeding units and covered 6 temperature summation zones in Heilongjiang Province were selected as experimental materials for grey correlation degree analysis between seed weight per plant and other major agronomic traits.The results showed that pod weight per plant,seed number per plant,and the number of 3-seed pod were the most important.And the total order was as below： pod weight per plantseed number per plantnumber of 3-seed podnumber of 2-seed podstem weightnumber of 4-seed podpodwall thicknessnumber of 1-seed podseed widththe number of nodes in main stemseed sizeplant height2-seed pod width seed length2-seed pod lengthpodding height.The results clarified the contribution of other agronomic traits to soybean yield,which could be the reference for soybean breeding.
