Interrelationships between grain yield and its components were determined by genotypic correlation and path co-efficient analysis in eighteen maize lines/hybrids. The results indicated that grain yield was positively and significantly associated with all parameters studied. The results also showed that number of kernels row-1 has maximum positive direct effect on grain yield. It was followed by 1000-kernel weight, ear length and number of rows ear-1. Ear height had negative direct effect on grain yield. It was concluded that cumber of kernels row-1, 1000-kernel weight, ear length and number of rows ear' were the main yield components.
