Genetic Variability, Heritability and Genetic Advance as per cent of Mean for Pod Yield and its Components in Virginia Bunch Groundnut (Arachis hypogaea L.) in Summer 2013

摘要

An investigation was carried out in 10 Virginia bunch groundnut genotypes to assess the variability, heritability and genetic advance as per cent of mean for nineteen characters namely days to 50% flowering, SPAD chlorophyll meter reading 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). The results revealed that highest PCV and GCV were observed for biological yield per plant and biological yield per hectare respectively. High heritability accompanied with high genetic advance as per cent of mean was recorded for no. of mature pods per plant, biological yield per plant, pod yield per plant (g), biological yield per hectare (q), pod yield per hectare (q), harvest index, kernel yieldperplant (g), kernel yield per hectare, 100 kernel weight and oil yield per hectare (q) indicating the preponderance of additive gene action which may be exploited through simple selection procedures.
