In order to select the dryland winter wheat varieties suitable for the promotion of rain-fed planting in southern Ningxia,this study analyzed the comparative test results of 17 cold-resistant and drought-resistant winter wheat varieties breeded in the mountainous area of southern Ningxia by using the grey system theory association analysis method.The results showed that the correlation between winter wheat yield and yield was in the order of 1 000-grain weight,hectare panicle number,plant height,grain number per panicle and panicle length.Among the tested varieties,the top 5 winter wheat varieties from high to low were Chang 5385-1,Longjian 103,X0309-15,Longjian 107 and Ningdong 16 in terms of comprehensive effects of yield traits on winter wheat yield.In summary,the yield of winter wheat was most affected by thousand-grain weight and panicle number per hectare,and the five winter wheat varieties Chang 5385-1,Longjian 103,X0309-15,Longjian 107 and Ningdong 16 had the most outstanding comprehensive performance in the experiment,which provided a theoretical basis for the breeding and promotion of ideal winter wheat varieties in the mountainous areas of southern Ningxia.
