In order to determine the growing characteristics and detecting the morphological bases of yield difference, study of relations between different traits with each other and with grain yield, determining the most important effective traits on yield in hybrids of seed corn and comparison of native and foreign hybrids had been studied and classification of them had been done on the basis of morphological traits. For this purpose an experiment carried out in 2007 at Moghan agricultural research center. In this experiment, 28 hybrids of seed corn (18 foreigner hybrids and 10 native hybrids) were studied in two different experiments with using a complete randomized block designed in 4 replications. Hybrids of both groups had meaningful differences in some characteristics. In this test some of medium maturing foreigner hybrids had low yield in comparison with the early maturing native hybrids, this result showed the different reactions of these hybrids in studied test conditions (P<0.05). Public heritability, the yield, number of seed rows, number of seeds per row, 1000- grain weight, plant height, ear height, number of tassel branches, number of leaves, location of appearance of ear, And length of leaf in hybrids of these two groups was high.
