Abstract

A generation means analysis of resistance to Curvularia lunata [Cochliobolus lunatus] and F. moniliforme [Gibberella fujikuroi] was carried out in the parental, F1, F2 and backcross generations of 8 crosses representing different combinations of susceptibility (high X high, high X low and low X low). The results indicated large dominance effects and significant epistatic effects for resistance to both pathogens. In a majority of crosses duplicate epistasis governed resistance to F. moniliforme. Additive and additive X additive effects were less important than dominance effects. It is suggested that intercrossing of early segregating material followed by selective inbreeding could improve resistance to both pathogens.
