Description 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.
