    Abstract:

    1307 local edible bean germplasm resources in Jiangxi were investigated and analyzed. The edible bean germplasm resources in Jiangxi were distributed in 89 counties ( cities and districts ) of 11 prefecture-level cities, among which Shangrao City, Yichun City, Ganzhou City, Jiujiang City, Ji 'an City and Fuzhou City had the largest number of resources. The distribution quantity of edible bean resources in Jiangxi decreased with the increase of altitude. he edible bean germplasm resources in Jiangxi Province cover 7 genera and 12 species. The cowpea resources have strong ecological adaptability, wide distribution area and the largest number. In addition to cowpea, the resources of mung bean, bean and adzuki bean are abundant in the low altitude areas of Jiangxi Province, and the resources of common bean and Lima bean are abundant in the middle and high altitude areas. The higher diversity index of edible beans in various cities is concentrated in the altitude of 0 ~ 500m ; cowpea, mung bean, rice bean and pea resources were abundant in Shangrao City, Yichun City, Jiujiang City, Ji 'an City and Pingxiang City. Cowpea and mung bean resources were abundant in Yingtan City, Xinyu City, Jingdezhen City and Nanchang City. Cowpea, bean and pea resources were abundant in Ganzhou City. Cowpea, rice bean and common bean resources were abundant in Fuzhou City. hrough phenotypic identification, the qualitative and quantitative traits of 449 cowpea resources with the largest number were analyzed. The diversity indexes of the eight quality traits were in the order of grain color > tender pod color > flower color > leaf shape > pod shape > mature pod color > grain shape > growth habit. The variation coefficients of pod length and 100-seed weight were the largest in quantitative traits, which had great potential for improvement. According to the comprehensive performance of agronomic traits, quality, resistance and yield, 30 excellent germplasm resources of different crop species were selected. These excellent germplasm resources of edible beans have great potential for excavation, which is of great significance for accelerating the innovative utilization of edible bean germplasm resources in Jiangxi.
