ABSTRACT
An experiment was carried out in 10 Virginia bunch groundnut genotypes to assess the variability, heritability, genetic advance and genetic advance as per cent of mean for nineteen characters viz., days to 50% flowering, SPAD chlorophyll meter reading (SCMR) at 40, 50,60,70 DAS and at maturity, days to maturity, number of mature pods per plant, biological yield per plant (g), pod yield per plant (g), biological yield per hectare (q), pod yield per hectare (q), harvest index, 100 kernel weight (g), shelling percentage, kernel yield per plant (g), kernel yield per hectare (q), oil content (%) and oil yield per hectare (q) over three seasons viz., Late Kharif (2012), Rabi (2012-13) and Summer (2013). The components of variance revealed that the phenotypic coefficient of variation (PCV) were higher than genotypic coefficient of variation (GCV) for all the characters studied indicating the role of environmental variance in the total variance. The results revealed that highest PCV and GCV was observed for biological yield per hectare. High heritability accompanied with high genetic advance as per cent of mean was recorded for kernel yield per plant (g), kernel yield per hectare (q), 100 kernel weight and oil yield per hectare (q) indicating the preponderance of additive gene action which may be exploited through simple selection procedures.
Key words: Genetic advance, heritability, groundnut, variability, SCMR
