 ABSTRACT

The present study was carried-out to assess genetic variability, correlation coefficients, path analysis in 60 genotypes of groundnut. The observations were recorded on 14 characters. The highest genotypic coefficient of variation was observed for plant height. Heritability was observed high for days to 50% flowering followed by biological yield per plant, number of matured pods per plant, shelling out-turn, plant height, pod yield per plant, number of pods per plant, number of immature pods per plant, 100-kernel weight, sound mature kernel, harvest index, days to maturity, number of branches per plant.Genetic advance expressed as percentage of mean was found high for plant height followed by number of matured pods per plant, pod yield per plant, number of immature pods per plant, biological yield per plant, number of pods per plant, harvest index, days to 50% flowering, shelling out-turn and 100-kernel weight. Pod yield per plant was significantly and positively correlated at both genotypic and phenotypic levels with number of matured pods per plant, number of pods per plant, sound mature kernel, 100-kernel weight, biological yield per plant and harvest index. Whereas, matured pods per plant 100-kernel weight, biological yield and harvest index showed high positive direct effects on pod yield per plant. Thus, these characters were identified as the most important yield components and due emphasis should be placed on these characters while selecting for high yielding genotypes in virginia groundnut.
