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. :
