新疆南疆冷凉区域不同大豆品种(系)的熟期与产量比较分析OACHSSCD

Soybean is an important grain and oil crop originated in China.It is cultivated in most areas.Soybean varieties suitable for planting in Southern Xinjiang are scarce.Therefore,in this study,23 approved varieties(lines)were uesd to carry out variety compar-ative experiments in order to screen out varieties or lines with suitable growth period,high quality,high efficiency and high yield.To further explore the production potential of excellent soybean varieties and provide seed selection ideas for large-scale promotion and planting in the Southern Xinjiang region.This study conducted an investigation and comparative analysis on soybean growth period,leaf shape,plant height,pod number,lodging resistance,actual harvest yield and other trait indicators.Thus,it can be concluded that soybean varieties with better adaptability to the local environment and high yield are better.The results of variety comparison test show that the yield of varieties such as'Xinzhendou 8''Jiyu 86''Xinzhendou 14'and'Zhonghuang 30'ranked higher,the plot yield reached more than 5 125.00 kg·hm-2,far higher than the average yield level in China.Therefore,these varieties are suitable for pro-motion and application in Southern Xinjiang from the perspectives of yield and growth period.
