The results showed genotype of heading time in Nanjing 11 was E1E1 e2e2 E3E3 SelSel and also included a recessive inhibitor i-Sel for photoperiod-sensitivity as well. Meanwhile, the two photoperiod-sensitive genes, E1 and Sel, in Nanjing 11 were also identified by crossing with QTL nearly isogenic lines of Nipponbare, NIL(Hdl )and NIL(Hd4)which have complementary effects.展开更多
