Abstract： The Shanxi province of China harbors diverse and abundant food legume germplasm resources with significant value on research and breeding.This study reported a systematic evaluation of food legume diversity in Shanxi province，based on the data obtained from“The Third National Crop Germplasm Resource

Surveyand Collection Action".Our analysis of 1907 accessions revealed substantial taxonomic diversity， encompassing1 family（Fabaceae），8 genera，and14 species.Based on ecological habits and end-use，these germplasm was clasified according to three ecological adaptation categories （cool-season，temperate-season and warm-season food legumes）and six utilization categories.The germplasm resources collcted from 11 prefecturelevel cities are ranked：Linfen，Xinzhou，Lvliang，Yuncheng，Datong，Jinzhong，Changzhi，Jincheng， Taiyuan，Shuozhou and Yangquan. Common bean represented the most widely cultivated and abundant germplasm，followed by cowpea，mung bean，and pea.Geographical distribution patterns showed distinct regional specialization：Cool-season food legumes predominated in central and northern regions of Shanxi province，temperate-season food legumes in central and southern areas，while warm-season food legumes were distributed in both north and south regions.Altitude distribution analysis revealed that 863 accesions were collected at 801-1200 meter elevation，followed by 594（ 1201-1600m ），23（ 0-400m， and4 >2000m ）.From the perspective of soil types of the source of germplasm resources，the source of 1907 resources are divided into 7 soil classes，10 soil great groups，and 21 sub-categories.Among the 10 soil great groups，cinnamon soil has an absolute advantage，with atotal of1247 resources fromthis soil great group，folowed by chestnut cinnamon soil and loessial soil.The number of brown soil resources is the smallest，with only1 colection.Collectively， through systematic investigation and field evaluation of these food legume germplasm accessions from Shanxi province，this study provides comprehensive characterization of collctions from“The Third Crop Germplasm Resource Survey and Colection Actions”，providing implications for their research，utilization，utilization and conservation in the region.
