ABSTRACT

This experiment was conducted in spring 2013 by using full diallel cross among six maize inbred lines. The different traits for F1s cross and parents with control were carried out during spring 2014 at the Coll. Agric. Univer. Duhok. Using Randomized Complete Block Design each treatment with three replications. The results showed that there was significant variance among them so the parent IK8 was more distinctive than other parents in the following traits; days to 75% tasseling, ear diameter, ear length, and yield plant -1 , the performance of the cross (IK8 x TH613) was good because it had high yield plant -1 followed by the crosses (IK58 x HS) and (HS x UN44052), and the cross (IK58 x TH613) was earlier than other crosses, some reciprocal crosses showed positive maternal effect for specific traits like cross (IK58 x OH40) in ear diameter and number of kernels row -1 , cross (HS x IK8) in ear length and yield plant -1 , and cross (UN44052 x IK8) in 300 kernel weight. The highest value of heritability in broad sense was for ear height and yield plant -1 with 0.94, whereas the genetic advance was medium for yield plant -1 and was low for other traits.
