野生小豆种质资源植株形态性状多样性分析

对来自中国、日本、韩国、缅甸4国的55份野生型、40份半野生型小豆种质资源植株形态性状的多样性进行分析,结果表明,野生型小豆与半野生型小豆在株高、平均成熟期、子粒颜色、百粒重等性状方面有明显的差别。95份小豆种质资源通过聚类分析,截值为1.488时可划分为5大类群。来源于缅甸和中国的野生型小豆种质各聚为1个类群,韩国和日本的种质混聚为3个类群。缅甸种质具平均成熟期长、茎秆粗、主茎分枝数多、百粒重轻等特点。中国贵州野生型种质植株较高、茎秆较细、单荚粒数较多、平均成熟期较长。日本野生型种质具有丰产特征。日本和韩国的半野生型小豆,平均成熟期较其他类群早、百粒重高、明度指数高。

The Morphological Diversity Analysis of Wild Adzuki Bean Germplasm Resources

95 accessions of wild adzuki bean germplasm resources from China,Japan,Korea and Burma,were analyzed for their morphological genetic diversity.The results showed that wild and weedy adzuki bean were obviously different in some characters,such as plant height,maturity period,seed color and 100 seed-weight and so on.Based on the morphological data,95 accessions were clustered into 5 groups.Wild adzuki bean from Burma and China,were clustered into two groups,respectively.The last three groups were from Japan and Korea.The accessions from Burma,had longest growth period,widest diameter of stem,more plant branch and smallest 100-seed weight.The wild germplasm resources from Guizhou of China had longer plant height,thinner stem,more seeds per pod,longer growth period.The Japanese wild germplasm had highest grain yield per plant.The germplasm with shortest growth period,highest 100-seed weight,highest value in L*,a*,b* were all weedy type from Japan and Korea.
