This study was conducted to compare the agricultural characteristics of total 444 common bean accessions from Korea (296), China (76), and El Salvador (72). Days to flowering were ranged from 41 to 83 days with an average of 61 days. Days to sowing to maturing were ranged from 86 to 143 days with an average of 104 days. Common beans from El Salvador tend to bloom and mature 3 to 7 days earlier than Korea and China accessions. In growth habit, over 50% of Korea and China accessions were indeterminate and climbing type, but 90.1% from El Salvador were Semi-determinate and climbing type. Qualitative traits were much different among three countries. Eighty-two percentage of immature pod colors were dark pink from El Salvador, but many of those were pale yellow from Korea (77.6%) and China (61.8%). Seed shapes were divided into four types of round, oval, cubic and kidney type, and the highest percentage of those were 30.4% with kidney type. The highest of those was 36.6% with oval type from Korea, 55.3% with kidney type from China and 79.2% with cubic type from El Salvador. Morphological characteristics of common bean from El Salvador were much different from those of Korea and China, which is necessary to collect more germplasm from its native and expand genetic diversity of common beans. Four hundred thirty-five common beans from Korea, China and El Salvador were analyzed using SSR markers. Ninety-two alleles were detected with a lowest of 6 at the BM161, BM181 and a highest of 18 at the BM154, BM160. The average polymorphism information content (PIC) was 0.72. To similar with population size among three countries, 292 Korean accessions divided four replications with 73 accessions. As a result genetic diversity was the highest of 0.73 in Chinese populations, while the lowest of 0.48 in El Salvador populations.
