Genotypic ¹ (above diagonal) and phenotypic ² (below diagonal) correlation coefficient estimates for each pair of traits

	TL	SD	KR	DTA	DTS	PH
TL		0.97*	NS	NS	NS	0.51*
SD	0.74*		NS	NS	NS	NS
KR	−0.31*	−0.31*		0.75*	0.71*	0.51*
DTA	NS	NS	0.30*		0.99*	0.66*
DTS	NS	NS	0.28*	0.96*		0.65*
PH	0.24*	−0.06	0.24*	0.51*	0.48*

TL, tunnel length; SD, stem damage; KR, kernel resistance; PH, plant height; DTA, days to anthesis; DTS, days to silking.

¹ Genotypic correlation coefficients were considered significant, *, when exceeded twice its standard error; NS, not significant.

² Phenotypic correlation coefficients were considered significant, *, at 0.05 probability level according to Steel and Torrie [59]; NS, not significant.
