  1. GL grain length (mm), GW grain width (mm), LWR the ratio of grain length to grain width, GT grain thickness (mm), TGW thousand grain weight (g). The data of the left lower and the top right triangles in the Table 2 are the correlation coefficients in F2 and F2:3 populations, respectively. ** indicate significance at P < 0.01
