Abstract: In order to study the effect of premature senility on yield components of millet hybrids, the study adopted a randomized complete block design with eight hybrids (bred by Crop Research Institute, Shanxi Academy of Agricultural Sciences) and the‘Millet 49’, and the correlations of yield components and degree of premature senility were analyzed with multiple comparisons and cluster analysis. The results showed that the control had the highest yield under the lightest degree of premature senility. The yields of other materials gradually declined as the premature senility was intensified, and the reduction of the yield ranged from 12.35%-36.14%. There were significantly negative correlations between the degree of premature senility and grain weight per ear, thousand kernel weight and yield. The premature senility had some correlations with parent infertility of the hybrids. In conclusion, the premature senility seriously affected the yield of the millet hybrids, so we should choose the anti- premature senility genes with good quality.
