Correlation coefficients for four kernel traits in CSSLs × Zheng58 and CSSLs × Xun9058 populations.

Populations	Trait	Kernel length	Kernel width	Kernel thickness	100-kernel weight
CSSLs × Zheng58	Kernellength		0.25**	−0.09	0.19**
	Kernelwidth	0.25**		0.05	0.35**
	Kernel thickness	−0.24**	0.06		0.27**
	100-kernels weight	0.20**	0.31**	0.04
CSSLs × Xun9058	Kernellength		0.25**	−0.10	0.21**
	Kernelwidth	0.16		0.05	0.36**
	Kernel thickness	−0.14	0.03		0.27**
	100-kernel weight	0.03	0.21**	0.16*

Correlation coefficients for phenotype and mid-parent heterosis of each trait are listed above and below the diagonal. ^{*, **}p < 0.05 and p < 0.01, respectively.
