Abstract:
The present investigation was carried out with 66 genotypes of peanut, pooled from ICRISAT, Patancheru, Hyderabad, ARS, Kadiri and RARS, Tirupati and experiment laid out in a randomized block design with two replications at Agricultural College farm, Bapatla, Guntur, Andhra Pradesh during kharif – 2019 to study the genetic variability on 21 characters of peanut. For all of the traits, analysis of variance revealed that the mean sums of squares owing to genotypes were significant.. Results of genetic parameters showed that traits viz., number of mature pods per plant, number of immature pods per plant, weight of pods per plant, kernel weight per plant, 100 seed weight, free amino acids, total soluble sugars and oleic linoleic acid ratio showed high genetic variability (GCV and PCV), high heritability (Hbs) coupled with high genetic advance as per cent of mean (GAM), indicating the predominance of additive gene action in these traits. Direct selections for higher phenotypic values of these traits will be effective in improvement of these characters among the genotypes.
