Genetic variability, correlation and path coefficients were studied in a set of 23 early maize germplasm. There was a wide range of variability among all the characters studied. The characters viz.. 1000-grain weight and grain yield had high heritability estimate and genetic advance. High positive associations were observed between grain yield on the one hand, and ear length, ear diameter, number of rows per cob and 1000-grain weight on the other. Path coefficient analysis revealed that ear diameter. ear length, 1000-grain weight and number of rows per cob were important yield con- tributing components.
