Genetic Variability and Character Association Studies in Groundnut (ArachishypogaeaL)
Journal Title: Scholars Journal of Agriculture and Veterinary Sciences - Year 2017, Vol 4, Issue 10
Abstract
Abstract:An attempt was made to evaluate the genetic variability and association of different component characters with pod and kernel yield plant-1 in groundnut at District Seed Farm of Kalyani, Bidhan Chandra KrishiViswavidyalaya, West Bengal during rabi 2014-15. Nineteen genotypes were grown in Randomized Block Design with three replications and evaluated for thirteen characters. Highly significant differences and adequate variability were obtained among the genotypes for all the selected characters. Analysis of variance revealed the existence of significant differences among genotypes for all characters studied. High GCV, high heritability coupled with high genetic advance as percent of mean were observed in case of kernel yield plant-1, no. of pod plant-1, no. of kernel plant-1 and 100 kernel weight indicating the role of additive gene in expressing these traits and effectiveness of selection. Correlation studies and path coefficient analysis revealed the importance of plant height, no. of pod plant-1, no. of kernel plant-1, shelling %, SMK, harvest index as they had positive direct effects on pod yield and kernel yield and should be considered for improvement in yield. Keywords:variability, heritability, correlation, path analysis, groundnut
