English Abstract

Half diallel crosses involved 5 inbred lines of maize to estimate some genetic parameters of F1 hybrids and parents.

The experiment was conducted at Grdarash Research Station in Collage of Agriculture/ Erbil.

In fall season 2014 half diallel crosses among inbred lines were done 10 hybrids were obtained with 5 parents were planted in yield trail in R.C.B.D with three replication.

The results showed highly significant differences among genotypes for most characters.

The ratio of σ2 GCA/ σ SCA was less than one for number of days to 50% tasseling, plant and ear height, ear length,300 kernel weight and yield ton/ha.

The average degree of dominance was more than one indicated the important of non-additive genes action in the inheritance these characters.

Heritability in broad sense ranged from 0.404 for 300 kernels weight to 0.84 for ear length.

While narrow sense heritability was very low for all characters indicate the hybridization method suitable to improve these characters
