“…After three generations of screening with 28 markers, combined with conventional breeding, the promising lines Q5DB-Saltol were selected to develop the next generations. Previously, we also have successfully genotyped BC generations by using the above markers of the crossed of the AS996, BT7, the elite Vietnamese rice cultivars (recipient plants) and FL478 (carrying Saltol QTL, as the donor plant) (6,24) 3,4,5,6,10,11,12,13,16,17,18,19,29,30,32 33,34,36,37,39, 44,45,46 showed homozygous DNA band from Q5DB. Other plants were possessed heterozygous DNA bands…”
