Correlation studies in groundnut

Abstract

For effecting dependable selection in breeding groundnut varieties suited to kharif uplands and summer rice fallows, genotypic correlation studies and path analysis were done based on 18 characters collected from 80 divergent groundnut varieties and the results compared and contrasted. There are differences in the direction, degree of relationship and relative effects for important characters on the economic trait on both the situations. Hence, in selecting ideal genotypes for the two situations, differential considerations had to be given for the component characters.
