Table 3.

Correlations among grain-related traits in combined environments

	TGW	LWR	GL	GW
TGW	1
LWR	0.165*	1
GL	0.550**	0.769**	1
GW	0.382**	−0.662**	−0.033	1

The abbreviations for the four traits (TGW, LWR, GL and GW) are the same as Table 2. Asterisks indicate significant correlation coefficients:

^*P ≤ 0.05;

^**P ≤ 0.01.
