摘　　要：应用灰色理论对8份芸豆种质资源的6个主要经济性状进行分析,评价创新种质的综合表现及各主要性状的相互关系,为芸豆新品种选育提供科学依据。创新种质资源中以2245产量最高,关联分析结果表明单株荚数、百粒重和单株粒数是影响产量的主要因子。Grey Theory was employed to analyze six main economic characters of 8 new germplasm accessions of Kidney bean. We evaluated comprehensive performance of enhanced germplasm and interaction of main characters which could be scientific germplasm, and results showed that affected the yield. basis of kidney bean improvement. The yield of 2245 was highest in all pods/plant, 100- seed weight and seeds/plant were important factors that
