QTL Mapping of Traits Associated with Dual Resistance to the African Stem Borer (Busseola fusca) and Spotted Stem Borer (Chilo partellus) in Sorghum (Sorghum bicolor)

Table 6

Direct and indirect effects of B. fusca damage traits on total grain yield at Embu site.

Character	Correlation with		Indirect effect via
	Grain yield	Direct effect	DH	EH	LD	ST
DH	-0.96	42.62	—	-0.0012	-0.0007	0.004
EH	-0.96	4.927	0.0026	—	0.0132	-0.0325
LD	-0.96	37.62	0.0005	0.0031	—	-0.0001
ST	-0.96	19.32	0.0001	0.001	0.0057	—

DH=deadheart damage; EH=number of exit holes; LD=leaf feeding damage; ST=stem tunneling damage; indicates that data is significant at the probability level.
