‘*’, ‘**’ indicate that the correlation is significant at 0.05 and 0.01 probability levels, respectively. RIL, recombinant inbred line population in maternal and paternal testcross trials, respectively; BC, backcross populations including maternal and paternal BC (BC/M and BC/P) populations. *: referred to QTLs identified in one BC/M trial, the remaining QTLs identified in three BC/P trials
