English Abstract

Half diallel cross among ten pure lines of maize (ZM47R, CA21R, ZM49R, G17, nbreed12, ZM5i.

Th97Alla-K122, G105, G54 and Th97A132-13-X14) was done, and then parents smd their crosses were planted in 18 July 2013 at Al-Salihea Villege, Al-Haweja using R.C.B.

Design with three replications, to assess the genetic of ear diameter and length, number of rows per ear, number of ears per plant, number of grains per ear, 100-grain weight and grain yield per plant.

General and specific combining abilities effects were estimated for parents and crosses respectively and gene actin controlled the inheritance of characters by Griffing (1956) and Hayman approach (1954).

The results of analysis of variance showed that mean square of general and specific combining abilities was significant for all studied characters except number of rows per ear and number of rows per plant, indicating the presence of additive and dominance gene effects controlling the inheritance of these characters.

The pure lines G105, ZM47R, Th97Alla-K122 G54 characterized by significant desirable general combining ability effects and high mean performance for most characters.

The two crosses cross (ZM5i x Th97Alla-K122) and (ZM5i x Th97A132-13-X14 showed significant desirable specific combining ability effects for most characters.

The dominance components values appeared higher than additive one, and the narrow sense heritability values was within the low range for all studied characters.
