ABSTRACT
The phenotypic and genotypic correlation for yield and its related traits were evaluated in sixty inbred lines of maize (Zea mays L.) at college farm, College Of Agriculture, PJTSAU, Rajendranagar, Hyderabad during kharif, 2013. Association studies revealed that the genotypic correlation coefficients were higher than the corresponding phenotypic correlation coefficients for almost all the characters under study. It indicated that strong inherent associations were somewhat masked at the phenotypic level due to environmental effect. grain yield per plant exhibited positive and significant association with plant height, ear height, ear length, number of kernels per row, ear girth, 100 seed weight, shelling percentage and number of kernel rows per ear both at phenotypic and genotypic levels. Therefore these characters could be used as criteria for selection of genotypes with high grain yield.
