Abstract:
Lodging was the major constraint of soybean production.The objective of this study was to achieve evaluation method in terms of root lodging resistance of soybean cultivars.Four index of lodging resistance (ILR) made up of different components were designed based on the mechanics as a comprehensive index to determine lodging resistance of 30 spring soybean cultivars.The ILR had significant negative correlation with percentage of prostrate plant.And the ILR test at podding stage with more components,(root weight stem intension) / (plant height top weight branch number)×100,was closely related to percentage of prostrate plant.The stem intension had positive effect on the ILR,but the top weight had the negative effect.The test results showed that the ILR might be used as an indicator to evaluate the lodging resistance of soybean objectively and accurately.
