摘  要:
[目的]研究新疆超早熟大豆品系(种)产量与主要农艺性状的关系,为新疆超早熟大豆新品种选育和品种改良提供参考。[方法]采用灰色关联度分析法,对16个超早熟大豆品系(种)的产量及主要农艺性状进行分析。[结果]产量与主要农艺性状的关联度由大到小排序为:单株粒重>株高>单株粒数>单株有效荚数>有效分枝>结荚高度>主茎节数>百粒重。[结论]单株粒重、株高、单株粒数、单株有效荚数是影响北疆超早熟大豆产量的重要因素,研究对高产、优质的超早熟大豆选育具有实际意义。

摘  要:
【Objective】This paper aims to study the correlation between the yield of the main soybean cultivars of earlier - maturing soybean varieties in Xinjiang,and their yield traits so as to provide a reference index for breeding or improving new varieties.【Method】The yield and agronomic characters of 16 soybean varieties were analyzed by using the grey relational grade analysis methods.【Result】The results showed that major agronomic characters related to yield were in following sequence:seed weight per plant > plant height > seed number per plant > pod number per plant > effective branch number > height of lowest pod > main stem node > 100 -seed weight number.【Conclusion】The result has practical significance for setting the goals of breeding or improving soybean varieties.
