    Abstract

    Three hundred and twenty two finger millet (Eleusine coracanu (L.) Gaertn.) germplasm accessions collected from Zimbabwe were evaluated at Aisleby and Henderson during the 1988/89 and 1989/90 rainy seasons. The data were recorded on grain yield and nine morphological traits to study the genetic variability and the heritability for each trait as well as the genetic and phenotypic correlations between traits. Differences between finger millet accessions for grain yield, finger length, finger width, number of fingers per head, 1000 grain weight and threshing percentage were significant at both locations, while differences in finger yield and number of productive tillers per plant were significant only at Aisleby. Number of days to flowering and plant height were recorded only at Aisleby and the differences among accessions were significant. Heritability in the broad sense for days to flowering was high (0.60). those for finger length. threshing percentage and 1000 grain weight were moderate (0.2 1 to 0.46), whereas the estimates were low (0.0 I to 0.29) for the rest of the traits. The correlation coefficients indicated that grain yield can be increased by selecting for high threshing percentage, high grain weight, early flowering and high finger yield.
