Coefficients of pairwise correlation among five grain size traits in the F₂ and F_2:3 populations

	GL	GW	LWR	GT	TGW
GL		0.276**	0.536**	− 0.025	0.598**
GW	0.309**		− 0.662**	0.470**	0.509**
LWR	0.488**	−0.677**		−0.439**	0.021
GT	0.025	0.515**	−0.460**		0.438**
TGW	0.614**	0.547**	−0.026	0.478**

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 F_2:3 populations, respectively. ^** indicate significance at P < 0.01
