Abstract: 【Objective】In order to select excellent soybean varieties suitable for planting in the central and western regions of Inner Mongolia,and provide a theoretical basis for soybean breeding in the future. 【Methods】In this experiment,ten new soybean varieties (lines) were collected from different regions,and their agronomic characteristics and yield indexes were compared and analyzed. 【Results】The results showed that the growth period of each variety was between 118-126 days,which belong to the north spring soybean medium ripe group variety and the yield change rule was:Zhongji 602>Chidou 201>Dongnongdou 251>Jiyu 491>Jinong 28>Jiyu 306>Jiyu 481>Jiyu 86>Longhuang 1503>Jiyu 494. Zhongji 602 had the highest yield of 3 440 kg/hm2,which was 10.9% higher than that of the control(P<0.01). The yield was significantly positive-correlated with the grain weight per plant(P<0.01),and positive-correlated with the number of pods per plant,the number of seeds per plant,and the 100-grain weight per plant(P<0.05);the number of seeds per plant was positive-correlated with the number of pods per plant,the grain weight per plant,the 100-grain weight per plant,and the yield(P<0.05). 【Conclusion】The central and western regions of Inner Mongolia were suitable for soybean varieties with moderate planting height,high productivity per plant,many pods and seeds per plant,and larger 100-grain weight. Zhongji 602,Jiyu 491,and Chidou 201 have outstanding comprehensive characteristics,which can be further planted in this area.
