Abstract: With 20 main wheat varieties of huaibei area as the test materials, a field experiment was carried out to study the yield components and the characteristics of resistance to late-sown in the condition of late-lowing. The results indicated that the average yield range of late-sown wheat was from 462.62 to540.85 kg/667 m2,and the variances of yield components was kernels per spike＞numbers of spike＞1000-grain weight. Correlation analysis showed that yield was correlated with number of spike(r=0.259),kernels per ear(r=0.578**) and 1000-grain weight (r=-0.360);Multiple regression equation of yield with its components was Y=71.964 3.483X1 5.327X2 2.533X3.According to the cluster analysis, all of these varieties were divided into four main and some secondary groups, wanke 06290,xuke 1,su 553 and zhoumai 27 which could be used as ideal varieties for late-sown planting in huaibei area of Anhui province were screened.
