摘要
以不同生态类型的10个大豆品种为研究材料,运用灰色系统理论,对影响大豆产量的主要数量性状进行灰色关联分析。结果表明:大豆产量与主要数量性状的关联度大小依次为单株粒数、株高、单株荚数、百粒重、节数、单株粒重、分枝数。
The study was conducted in ten soybean varieties with different ecotype. The related Grey System Theory was employed to analyze several characters that affect the soybean yield. The results show that the grey related degree between yield and the correlated characters could be put in order as： grains per plant, plant height, pods per plant, 100- kernel weight, branches per plant and grain yield per plant.
