Abstract
One hundred forty four finger millet landraces were collected from different regions of Ethiopia and some introduced from Eastern and south Eastern African (Kenya, Eritrea, Zambia and Zimbabwe) were planted with six improved varieties in RCBD design at Gute and Arsi Negele during 2011 cropping season to assess variability, heritability, genetic advance and association of quantitative traits. The analysis of variance indicated that the mean square due to location and genotype were highly significant (P#0.01) for all quantitative traits except ear weight for the latter case. Phenotypic coefficient of variation was higher than the corresponding genotypic and genotype by environment coefficient of variations for all traits. This implies, beside the genetic factors, environmental factors have high contributions for the variations observed. The higher heritability coupled with higher genetic advance noted for ear weight (71.14%), lodging index (53.49), finger length (41.94%), thousand grain weights (28.88) and grain yield per plant (26.34) indicated that the ease of phenotype based selection for the improvement of those traits. About 68.4% of the total traits association showed positive correlation. As obtained from path coefficient analysis, the higher and positive direct effect of productive tiller per plant (0.356) and thousand grain weight (0.285) and the positive direct effect of finger length, finger number, ear weight, number of grain per spikelet and culm diameter on grain yield indicated that any genetic improvement on those traits has positive contribution to improve productivity of finger millet.
