In the present investigation, phenotypic and genotypic correlation coefficients were estimated among 19 characters of 51 maize genotypes, to find out the association between grain yield and its contributing characters. Grain yield per plant significantly and positively correlated with plant height, ear height, number of kernels per row, number of kernels per ear, shelling percentage and test weight at genotypic and phenotypic basis. Observable correlations among different traits was confirmed through phenotypic correlation, actual correlation could be known through genotypic correlation only, which eliminates environmental influence. Genotypic correlation permits prediction of correlated response and evaluation of relative influence of one character on other. Genotypic correlation in particular is helpful in construction of selection indices.
