1T, tiller number; Ph, plant height; SL, spike length; SLN, spikelet number; GN, grain number; TGW, thousand grain weight; Ht, heading time; Mt, mature time; PM, powdery mildew resistance; Y, yield.
2Numbers left and right of “/” were the traits of landraces and of modern varieties, respectively.
3Trait GN was significantly different between L and M in three environments. VM/L (%) is the trait variations of population M compared with that of L.
