This experiment was conducted to evaluate on agronomic traits of Korean local adlay (Coix lachryma L.) germplasm, 281 cultivars (lines). The largest collected cultivars was from Kyungsangbukdo (56 cultivars), and the next was in the order of Cheonlabukdo (48 cultivars), Kyungsangnamdo (44 cultivars), Kyunggido (39 cultivars) Chungcheongnamdo (23 cultivars), Kangwondo (23 cultivars), Cheonlanamdo (17 cultivars), and Chungcheongbukdo (16 cultivars) in distribution of collected region for 281 cultivars. In the growth stages, days to emergence from seeding were required $16.4{pm}2.03$ days, days to heading from emergence was required $73.6{pm}5.87$ days, days to ripening from heading was required $52.3{pm}4.91$ days and cultivation period was required $142.5{pm}5.87$ days. Culm length was $210.3{pm}16.39$ cm, no. of tiller per plant was $10.4{pm}2.13$, culm diameter was $11.7{pm}1.09$ mm, fruiting position was $4.6{pm}0.82$ node, no. of main culm node was $11.1{pm}0.78$, degree of lodging was $5.3{pm}3.42$ and severity of leaf blight was $56.1{pm}0.78$ in the growth characteristics of the germplasm. In the yield of component, no. of grains per $m^2$ was $5,938{pm}2,152$, percentage of ripening was $67.7{pm}33.12$, 1,000 grains weight was $123.8{pm}33.76$ g and grain weight was $473.0{pm}207.90$ g. Grain weight was correlates significantly positively with no. of main culm node, percentage of ripening and no. of grains per $m^2$ among agronomic traits. Correlation coefficient between grain weight and 1,000 grain weight was positive, while grain weight and severity of leaf blight was significantly negative. Correlation coefficient between grain weight and days to ripening from heading was significant negatively.
