摘要: 【目的】对绿豆主要栽培品种进行遗传多样性分析,为绿豆新品种的选育提供优异资源。【方法】利用差异性、多样性、聚类分析等方法,对113份绿豆主栽品种的15个主要农艺性状和相关产量因子进行分析。【结果】113份品种的农艺性状表现出广泛的遗传变异,其中荚长的遗传多样性指数最高,其次是单荚粒数;抗病性的变异系数最大,抗倒伏性次之,单荚粒数最小;聚类分析将113份绿豆品种划分为3个类群,第Ⅰ类群可以作为选育高秆、适宜机械收获的育种材料;第Ⅱ类群虽然丰产性较低,但可作为选育矮秆、大籽粒的育种材料;第Ⅲ类群属于高产类群,此类群可作为选育高产以及幼茎色的育种材料。【结论】113份绿豆品种中蕴含着丰富的遗传多样性和可利用的遗传特异性,在高产、高秆、直立和籽粒大小等方面具有可育种和宜机械生产利用的优异资源。

Abstract: 【Objective】To analysis the genetic diversity of main cultivars mung bean and to provide excellent resources for mung bean breeding.【Methods】15 main agronomic characters and related yield factors of 113 main cultivars were analyzed by means of difference,diversity and cluster analysis.【Results】The agronomic characters of 113 varieties showed extensive genetic variation,in which the genetic diversity index of pod length was the highest,followed by the number of seeds per pod.The variation coefficient of disease resistance was the largest,followed by lodging resistance,and the number of seeds per pod was the smallest.113 mung bean varieties were divided into three groups by cluster analysis,and groupⅠcould be used as breeding materials for tall stalks and suitable for mechanical harvest.Although the yield of group Ⅱ was low,it could be used as breeding mater for short stalk and large grain,and group Ⅲ with high-yield,which could be used as breeding material for high yield and young stem color.【Conclusion】113 mung bean varieties contained rich genetic diversity and had excellent resources for breeding and mechanical production of high yield,tall culm,erect and grain size.

Key words: Mung bean varieties, Agronomic characters, Genetic diversity, Clustering analysis
