| Abstract | ||
| Two pure lines of maize (HS and DC-r-10 ) were planted on full season for crossing between them ,the pure lines tester of Maize (ZP607 , ZP707 , SY7 , SY19 , OH40 and ART-B12 ) were crossed with three families , HS , DC-r-10 and (HS * DC-r-10 ). Genotypes . (lines , families and hybrids )were planted by using randomized complete block design with three replications for the study of epistasis , estimation of variance components and some genetical parameters for , dateanthesisof male and female , plant high, ear high , leaf area , number of leaves , number rows per ear , number of grains per row, number of grains per ear , 500 –grains weight and grains yield per plant . mean squares for genotypes , hybrids and parents (testers and families ) were significant for all traits analysis of variance for epistasis gene action test indicated the absence of epistasis additive and dominance variances were important for inheritance of most traits . brood sense heritability estimates between 60% for number grains per ear and 99% for leaf area while narrow sense heritability ranged from 15% for 500 grains weight and 78% for date anthesis , ( as parent of the mean ) was found to be high for number of grains per ear , low for number of leaves per plant , the expected genetic gain highest for number of grains per ear and lowest for leaf area . the conclusion of the study could improvement the characters with selection for elite hybrids for produce the hybrids or elite inbred | ||
