以96份糜子种质资源为试材，对其9个农艺性状的遗传多样性进行了分析。结果表明：糜子种质资源遗传变异丰富，其中，主茎粗变异系数最大（35.54％），其次是单株粒重（26.36％）和单株穗重（25.15％）；除主茎节数外，其他农艺性状的遗传多样性指数均＞0.8。基于农艺性状的聚类分析和主成分分析结果显示，96份糜子种质分为4大组群；主要农艺性状可归纳为株高、主穗长、单株粒重、单株穗重、千粒重5个主成分，累计贡献率为89.417％。该结果可为糜子育种时选配亲本提供参考依据。

The genetic diversity of 96 proso millet germplasm resources about 9 agronomic trocits were analyzed. The results showed that there was wide genetic variation of proso millet , the main stem diameter variation coefficient was maximum ( 35.54%), the grain weight of per plant and panicle weight were followed, the variation coefficient of them respectively were 26.36% and 25.15%. The index of genetic diversity of the agronomic traits were more than 0.8 except node number. Based on cluster analysis of agronomic traits and principal components analysis indicated , 96 proso millet germplasms were divided into 4 groups. The main agronomic traits could be summarized as 5 principal components, such as the plant height, panicle leghth, grain weight per plant, panicle weight and 1000 -grain weight, the cumulate contribution rate was 89.417%. The results could provide references for selecting parental in millet breeding .
