摘　　要：在相同遗传背景下,采用两对叶型不同的大豆品系A31和6059,探讨了不同叶型对大豆产量性状、形态性状、生理指标及品质的影响。结果表明,叶型对其品质的影响是相同的,圆叶型大豆品系蛋白质含量高于尖叶型,而尖叶型大豆品系脂肪含量高于圆叶型;叶型对不同大豆品系农艺性状的影响有所差异,尖叶型大豆品系节间长度较短,四粒荚数较多;圆叶型大豆品系百粒重较大,但在产量方面差异不显著(A31品系F0.036=1.364<F0.05,6059品系F0.87=0.036<F0.05)。The effect of leaflet type on yield, morphological, physiological traits and seed quality was evaluated, using two pairs of narrow and broad leaflet soybean lines A31 and 6059 with the same genetic backgrounds. For different lines, the effect of leaflet type on quality was uniform. Entries with broad leaflets had higher protein content than that of with narrow leaflets, but oil contents were not. The effect of leaflet type on agronomic traits was different, narrow leaflet lines had shorter internodes length, more four-seed pods, while broad leaflet lines had larger 100-seed weight. There was no significant yield difference between leaflet lines.
