The seed quality parameters and maturity indices were studied in a set of fifty-five spreading and semi spreading type of groundnut genotypes (Arachis hypogea L.). The studies indicated the effect of season and storage periods on the seed quality parameters. The genotypes behaved differently in different seasons and under different storage periods. The summer grown groundnut seeds lost the seed quality progressively under storage and showed poor germinability both in laboratory and field conditions. A wide range of phenotypic coefficient of variation was recorded for pod yield per plant and its components traits. Higher phenotypic and genotypic coefficient of variation was observed for days to pod yield per plant, plant height and secondary branches per plant. For various characters the magnitude of genetic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), heritability and genetic advance as percentage of mean were found to be high. This indicated that additive gene action may be involved in the expression of these traits. High broad sense heritability estimates were recorded for most of traits which indicated that these traits were less influenced by the environment. These traits can be improved by simple selection procedure.
