Abstract
The differences between the two parental strains in
each cross as well as the F2 genetic variability estimates
for late wilt were found to reach the significant level
only for two resistant X susceptible crosses, namely, K6
X G4 and Rgll x G 303 A.
Highly significant negative heterotic effect and inbree
ding depression were detected for the two crosses. Resis
tance to late wilt disease was found to be partially domi—
nanted over susceptability in the two crosses. Epistatic
deviation of F2 (E1) and back crosses (E2) were significant
in the two crosses. Both additive and dominant types of
gene action were important in the inheritance of resistance
to late wilt disease. Furthermore, (ad) type of gene action
was more important than (aa) and (dd) types. High estimates
of heritability in both broad and narrow sense were found
in both crosses. Also, high predicted genetic gain estimates
were obtained in bِth crosses. :
