Abstract
The major objectives of the study were to evaluate genotypic yield performances of eleven maize genotypes and estimate variance components and heritability of yield and yield-related traits. The eleven open pollinated maize varieties were evaluated using randomized complete block design with three replications. The experiment was carried at National Maize Research Program, Rampur, Chitwan, Nepal out in winter season of 2013. The findings showed that the high genetic advance was estimated for yield per plant (80.15%), number of kernels per row (38.29%), plant height (26.20%) ear length (23.89%) indicating that these parameter were under the control of additive gene. Number of kernels rows per ear, plant height could be the important selection criteria in improving open pollinated maize varieties for high grain yield.
