摘要
为研究大豆耐密性状及与产量间的相关性,以150份大豆种质资源为材料,利用高密度与常规密度下各耐密性状的比值研究大豆耐密性状与产量的作用关系。结果表明:大豆株高、主茎节数、重心高度及倒伏率间呈显著或极显著正相关,有效分枝数与重心高度及倒伏率呈极显著负相关。其中倒伏率与产量呈极显著负相关,间接相关因子主要来源于重心高度及株高,有效分枝数与产量呈极显著正相关,间接相关因子主要来源于重心高度及倒伏率。因此,在高密度条件下与大豆产量密切相关的性状为倒伏率、重心高度及有效分枝数。该研究结果能够为耐密植大豆品种创新提供理论依据及优异材料。
In order to know the correlation of density tolerance traits and yield under different densities on soybean, 150 soybean germplasm resources were used to analyze the interactive relationship between different traits and yield under high density and conventional density. The results showed that there were significant or extremely significant positive correlation between plant height, main stem node number, center of gravity height and lodging rate. The correlation of available primary branches was extremely significant negative with center of gravity height and lodging rate. The correlation of yield and lodging rate was extremely significant negative and the indirect correlation factors come from the center of gravity height and plant height. The correlation of available primary branches and yield was extremely significant positive and the indirect correlation factors come from the center of gravity height and lodging rate. So the most relevant traits of yield were the lodging rate,the center of gravity height and the available primary branches. The results provide theoretical basis and excellent materials for the innovation of densi-tolerant soybean varieties.
