Abstract： This study conducted a genetic diversity analysis of 85 local adzuki bean germplasm resources collcted from Zhejiang province，China，during“The Third National Campaign of Crop Germplasm Census and Collection".These germplasm displayed uneven distribution across the province while exhibiting substantial genetic diversity. Analysis of quantitative traits revealed coeficients of variation ranging from 6.10% to 58.26% ， exhibiting the highest variability at yield per plant and the number of pods per plant.The Shannon diversity indices ranged from O.O2 to 2.43，peaking at plant height. The grain length positively correlated with grain width，pod length，and 10o-seed weight，and the plot yield positively associated to the numberof pods per plant andyield per plant.Principal component analysis stimulated five principal components，with acumulative contribution rate of 63.929% . The coefficient variation of11 qualitative traits ranged from 0% to 181.15% ，with the lowest and highest values at the color of young pod and pod dehiscence，respectively.The diversity index ranged from Oto 1.18，with the highest and lowest values at maturity and the young pod color，respectively. Cluster analysis categorized these resources into three major groups：Group I，with 17 resources， characterized by a relatively short overall growth period，short plant height，as wellas large seed length，seed width，and 100-seed weight；Group II，containing 37 resources，characterized by a medium maturity and relatively tall plant；Group II，with 31 resources，characterized by a long growth period，high pod length， pod width，number of pods per plant，and number of seeds per pod，as well as high yield and amino acid content.Four elite germplasm accessions were identified based on comprehensive scoring. Collectively，this study systematically evaluated the newly collcted adzuki bean germplasm resources in Zhejiang， providing a theoretical basis for adzuki bean germplasm innovation，breeding，and promoting the development of the adzuki bean industry.
