Abstract: Taking 57 new spring wheat strains as test materials, and Yongliang4 （CK1）, Nongmai2 （CK2） , Nongmai5 （CK3） as the control, the growth period of wheat, disease resistance, grain traits and plant agronomic traits and grain yield, the correlation of agronomic traits and grain yield and contribution of yield components were studied. The resuhs showed that the new varieties of increased yield were 2017j22, 2017j51 and 2017j52 compared with the three controls. In terms of tile growth period, these three strains have a growth period of nearly 90 days. In terms of disease resistance, leaf＇ rust is light or mediunl in these three strains. From the agronomic characters analysis, the three strains were characterized by groups, plant height between 75.3-82.1 era, plant number between 649.5-733.5 ten thousand/hm^2, tiller number between 466.5-594.0 ten thousand/hm^2, effective panicles between 36.1%-44.4%, the number of spike in 31.1-39.6 ten thousand/hm^2, 1000-grain weight between 38.1-39.7 grams, spike grain number between 35.9-45.5 grains/spike. At the same time, the cmTelation between grain number and grain yield was the largest, and the correlation coefficient reached 0.432.The diameter analysis showed that the number of grain per spike was the greatest contribution to grain yield, which was 1.846. The second was the nmnber of spike,and the contribution rate was 1.205. The indirect effect of the yield component was negative, and no contribution was shown. According to the analysis resuhs and the ecological conditions of Hohhot, the selection of new varieties of spring wheat should be based on the number of high panicle grains, while the number of panicles should be stable and the 1 000-grain weight should be increased.
