Abstract
Twenty eight inbred lines were investigated in the field experiment. The experiment was arranged in randomized complete block design with three replication in two vegetative seasons 2009 and 2010. Heritability in broad sense and genotypic coefficient of variation (GCV) were calculated based on analysis of variance. Wright’s path analysis was made and coefficients of correlation were calculated. Days until shedding had relatively high heritability (0.76), whereas moderate values were obtained for ear diameter and ear height. The greatest values of GCV were obtained in case of ear height, ear rows number and ear grain weight. Path analysis revealed that ear length and diameter had directly and indirectly the most significant influence on ear grain yield.
