Abstract：In order to screen the water-saving and high-yield wheat varieties, taking irrigation fre-quency as the major treatment and 10 wheat varieties as the minor treatment,the yield,yield components and water use efficiency of 10 wheat varieties under different irrigation frequencies were studied.The results showed that both the yield and the number of spikes per hectare increased with the increase of irrigation fre-quency,while the water use efficiency decreased.There was no coincident regularity between grain number per spike and thousand kernel weight.Correlation analysis showed that the yield was highly significantly corre-lated with the number of spikes per hectare, while had positive but not significant correlations with the grain number per spike and thousand kernel weight.According to comprehensive evaluation, Luyuan 502, Shan-nong 22 and Tainong 18 were screened out as better varieties with water-saving and high-yield characteris-tics, and this study provided references for selecting and popularizing of water -saving and high -yield wheat variety.
