KẾT QUẢ NGHIÊN CỨU CHỌN TẠO GIỐNG ĐẬU TƯƠNG TRIỂN VỌNG ĐT30 VÀ ĐT31

Two promising varieties of DT30, DT31 have been studied and bred from 2006 at the Legumes Research and Development Center. Variety DT30 has been selected in combination between DT26 and M103; DT31 has been selected in combination between LS17 and DT2001. Growth duration of varieties DT30, DT31 are between from 90 days to 95 days; they can be grown in three seasons per year. Grain yield of DT30 reached from 22.53 quintals/ha to 26.30 quintals/ha and increased from 21.9 % to 26.4% highly as compared to the control variety (DT84). For DT31, yield reached from 21.73 quintals/ha to 27.8 quintals/ha which was from 13.5 % to 22.2% higher than DT84. DT30 and DT31 varieties were lightly infected by rust, powdery mildew and downy.
