Abstract

When line X tester (6 X 16) material of Pennisetum typhoides was infected with Sclerospora graminicola the genotype X environment interaction for disease incidence was predictable; av. performance and line responsiveness seemed correlated. There was a positive correlation between mean performance and general combining ability effects for disease resistance in the parents. A simple major gene mechanism was apparently absent from many crosses but the parent 5054A appeared to transmit resistance to most of its hybrids. Good combining parents included 2 male steriles and 6 male parents. Narrow sense heritability estimates were quite high in individual environments and on a pooled basis. Line selection for resistance appears promising
