| Abstract | ||
| Factorial mating desiing involoing Four lines OF maize (Agr183 . w13R. W17.161 and R153) used as males and other five live lines (OH40. IK58. IK8. ZP and DK) used as females. The nine lines and crosses among them were planted using ACBDesing with three replications and data taken for traits: number of ears per plant length ead diamerer number of rows per ear ; number ofgrains per row 100 grain weight and grain yield per plant M arked significant heterosis was observed for almost al the traits examined lt was shown plant Marked significant heterosis was observed for almost al the traits examined lt was shown that nonadditive gene action was more important in the inheritance of all traits Among males (R153) and among femaler (lk8) were the best general combinors for the most of traits and the cross (W13RxZP)was the best specific combinor . | ||
