| Description |
Heterosis events of two traits – ear length and number of rows of the ear, are investigated. 24 experimental maize hybrids and 20 local populations (parental components) belonging 400-500 FAO group, are tested at under irrigation conditions. A positive significant correlation between both traits was observed, but their heterosis events are different. For ear length the better parent heterosis (BPH) have positive values in 14 cases with overdominance inheritance events. With the other hybrids negative heterosis was observed, with the character of an intermediate inheritance or positive dominance of the traits. For number of rows of the ear, for almost all test-crosses negative heterosis was found, but the degree of dominance is highly variable. A previous investigation of the maize hybrids similar results for these two traits, are observed.
