AB  - Determination of genetic variability with the
help of parameters such as genetic coefficient of variation,
heritability estimates and genetic advance are basic tools
used in plant breeding experiment. Sixteen groundnut
varieties were evaluated for quantitative parameters. The
oil analysis was conducted for groundnut genotypes
grown across four locations in Ethiopia. The experiment
was laid out in an RCBD with two replications. The
results of combined analysis of variance has shown that
high heritability with high expected genetic advance were
observed for stearic acid, arachidic acid, eicosenoic acid,
lignoceric acid and oleic to linoleic acid ratio indicating
the predominant role of additive gene action and the
possibilities of effective selection for the improvement of
these traits. However, heritability for oil content is low
showing that direct selection for oil content is difficult;
the possible improvement of oil content should be indirect
selection through highly heritable traits.
