Abstract

In a 9 X 9 diallel cross of nine genetically diverse Pennisetum typhoides inbred lines and their 36 F1 hybrids, the F1s generally had a larger leaf area and leaf number but thinner stems than the parents and both general (GCA) and specific combining-ability variances were highly significant in respect of these characters. Estimates of the average degree of dominance and heritability in the narrow sense showed the importance of additive-gene effects in the inheritance of leaf area and leaf number, but considerable nonadditive effects for stem thickness. The performance of parents was in agreement with their GCA effects. It is concluded that GCA could be used as a guideline for predicting the performance of cross combinations in Pennisetum
