Abstract
Nine inbred lines of maize (DK, SH, R153, ZP, OH40, W13R, IK58, Agr183 and IK8) were concluded in this study. Factorial mating design that suggested by Comstock &Robinson (1948 &1952) was used to perform single crosses among male lines (IK58, Agr183 and IK8) and female lines (DK, SH, R153, ZP, OH40 and W13R). The genotypes ( 9 inbred lines and 18 hybrids) were planted at The fields of College of Agriculture at Tikrit University by using randomized complete block design with three replications to estimate some genetic parameters: Phenotypic Variance components (Additive, Dominance and Environmental) also broad and narrow sense heritability, degree of dominance and expected genetic advance. The results showed that the dominance variance was more than additive one for most studied characters, where as the narrow sense heritability values were ranged from (3.12%) for plant height (as male) and (75.56%) for the same trait (as female). Average degree of dominance was exceeded one for most studied characters while values of expected genetic advance low to mederate and high for all characters. Key words: Zea mays, inbred lines, Factorial design mating.
