To identify some new suitable mungbean varieties for rainfed area in Huong Son, Ha Tinh, the experiment on 9 promising mungbean varieties was carried out in the summer seasons 2010, 2011. Local mungbean variety Tam was used as the local check. The experiment was designed by RCBD with 3 replications. The density was 25 plants/m2 ; Fertilizers application with dose of 40kg N + 60kg P2O5 + 60kg K2O + 1.000kg Song Gianh microbial-organic fertilizer + 500kg of lime. The results showed that: almost new mungbean varieties gave significant higher grain yield in comparison with local check. Varieties DX17 and DX208 belong to medium mature group (63-56 days), infected slightly with main diseases and insect-pest, they gave the highest average yield in both years 2010, 2012 (15.6 and 15.0 quitals/ha)
