| dc.description.abstract | Fifty landrace populations (1500 individuals) of chickpea (Cicer arielilllllJl L.) collected from ten different chickpea growing regions of Ethiopia were studied for variation of seven qualitative and ten quantitati~e traits. Shannon and Weaver diversity indices (H') were calculated for the qualitative characters, populations, regions of origin and altitude classes. The highest mean diversity index pooled over characters was observed in collections from Shewa (0.67±0.08) and Arsi-Bale (0.65±0.08) collections and the lowest mean for those from Hararghe-Sidamo and Garno Gofa (0.59±0.09 and 0.56±0.IO, respectivcly). The over-all mean diversity index for Ethiopia in this study was 0.64±0.OS. Relatively higher mean diversity index for traits pooled over the altitude classes were recorded in the higher altitude classes. The analysis of variance f6r the individual traits shows that much of the variation was within population and altitude groups. Multivariate methods including'cluster and principal component analysis were used to asses the pattern of variation using the ten quantitative characters. Cluster analysis using Ward's method grouped the fifty populations sampled from the ten regions into seven clusters, and into another eight clusters using both the qualitative and quantitative characters together. The Mahalanobis's distance (D') analysis also revealed the existence of considerable variability among the chickpea populations, and hence parental lines could be selected for hybridization and improvement of the crop. The isozyme test using ten different enzyme systems was not able to reveal any variation between the chickpea accessions, indicating a need for the use of more sensitive genetic markers in future studies. As indicated by the t-test undertaken for cmde protein content of the landraces, significant variations were observed which might indicate a niche for improvement.
