研究结果表明:1、除第1有效果枝高度与抗倒伏性呈正相关外,其余性状均与抗倒伏性呈负相关,其中有效果枝与无效果枝数比值及单株大铃数与抗倒伏性呈强负相关。2、通径分析表明:有效果枝与无效果枝数比值的直接或间接影响是造成多数性状与抗倒伏性呈负相关的最主要原因。第1有效果枝高度对抗倒伏性的选择最直接,黄萎病抗病性的间接选择对抗倒伏性的选择也有一定效果。
The results showed that: 1, except for the first effective branch height and lodging resistance was positively correlated, the rest of the characters were negatively correlated with lodging resistance, of which the effective branch and no effect branch number ratio and boll number per plant and lodging resistance was Strong negative correlation. Path analysis showed that the direct or indirect effect of the ratio of effective branches to ineffective branches was the main reason that most of the characters were negatively correlated with lodging resistance. The first effective branch height resistance lodging the most direct selection, Verticillium wilt resistance to indirect selection of lodging resistance also have some effect.
