Foundation projects: The Third National Survey and Collection of Crop Germplasm Resources; Reproduction, Cataloguing, Storage and Innovative Utilization of Dry Cropping Germplasm Resources in Jiangxi Province(JXXTCX202101-02)
对1307份江西地方食用豆种质资源进行调查分析,江西食用豆种质资分布在11个地级市的89个县(市、区),其中上饶市、宜春市、赣州市、九江市、吉安市和抚州市资源数量较多;江西食用豆资源分布数量随着海拔的升高而减少。江西食用豆种质资源涵盖7个属12个种,豇豆资源生态适应性强、分布区间广、数量最多;除豇豆外,江西低海拔地区绿豆、藊豆、小豆资源较为丰富,中高海拔地区普通菜豆、利马豆资源较为丰富。各地市食用豆多样性指数较高的集中在海拔0~500 m;上饶市、宜春市、九江市、吉安市和萍乡市的豇豆、绿豆、饭豆和豌豆资源较为丰富,鹰潭市、新余市、景德镇市和南昌市的豇豆、绿豆资源较为丰富,赣州市的豇豆、藊豆、黎豆资源较为丰富,抚州市的豇豆、饭豆、普通菜豆资源较为丰富。着重对数量最多的449份豇豆资源进行了质量性状和数量性状分析,8个质量性状的遗传多样性指数依次为粒色>嫩荚色>花色>叶片形状>荚形>成熟荚色>粒形>生长习性;数量性状中荚长和百粒重的变异系数最大,具有较大的改良潜力。根据农艺性状、品质、抗性和产量等综合表现,筛选出不同作物种类的优异种质资源30份。这些食用豆优异种质资源具有较大的挖掘潜力,对于加速江西食用豆种质资源的创新利用具有重要意义。
1307 local edible bean germplasm resources in Jiangxi province, China, were investigated and analyzed. These germplasm resources are distributed across 89 counties (cities and districts) in 11 prefecture-level cities, with the highest number of resources found in Shangrao, Yichun, Ganzhou, Jiujiang, Ji'an and Fuzhou cities. The distribution quantity of edible bean germplasm resources decreases with increasing altitude. These germplasm resources belong to 7 genera and 12 species, with cowpea resources exhibiting the strongest ecological adaptability, the widest distribution area and the largest number. In addition to cowpea, mung bean, bean and adzuki bean resources are abundant in the low altitude areas, while common bean and Lima bean are more prevalent in the mid- and high-altitude areas. The higher diversity indices of edible beans in various cities are concentrated at altitudes of 0 to 500 meters. Cowpea, mung bean, rice bean and pea resources are abundant in Shangrao, Yichun, Jiujiang, Ji'an and Pingxiang cities. Cowpea and mung bean resources are abundant in Yingtan, Xinyu, Jingdezhen and Nanchang cities. Cowpea, bean and pea resources are abundant in Ganzhou city. Cowpea, rice bean and common bean resources are abundant in Fuzhou city. Through phenotypic identification, the qualitative and quantitative traits of 449 cowpea resources, which had the largest number, were analyzed. The diversity indices at the eight quality traits were ranked (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 among quantitative traits, indicating significant potential for improvement. Based on the comprehensive performance of agronomic traits, quality, resistance and yield, 30 elite germplasm resources were identified. These germplasm resources have great potential for further exploration and are of great significance for accelerating the innovative utilization of edible bean germplasm resources in Jiangxi province, China.
