Genetic progress in stem lodging resistance of the dominant

发布时间：2021-10-26 00:18

　　Analysis of genetic progress for lodging-related traits provides important information for further improvement of lodging resistance. Forty winter wheat cultivars widely grown in the Yellow-Huai River Valleys Winter Wheat Zone（YHWZ） of China during the period of 1964–2015 were evaluated for several lodging-related traits in three cropping seasons. Plant height, height at center of gravity, length of the basal second internode, and lodging index decreased significantly in this period, and the ave...
