Rezumat

Abiotic stresses including submergence and salinity were the main hindrance to enhancing rice production in Vietnam. The objective of research was to use Marker Assisted Backrossing (MABC) technique to improve tolerance of rice to submergence and salinity. Four new elite rice lines of BC3F2 generations (AS996-Sub1, OM6976-Sub1, BT-Sub1, and KhangDan DB-Sub1), incorporating the Sub1 QTL as well as three other new elite lines (AS996-Saltol, OM6976-Saltol, and BT-Saltol), incorporating the Saltol QTL, were developed through MABC techniques. All the seven elite lines retained nearly 100% of original genetic backgrounds, with newly incorporated traits of tolerance to submergence or salinity. The improved lines are being released to the farmers and grown in the coastal areas to cope with the climate change.
