Abstract: According to Griffing-Ⅳ Mod-Ⅱ, Cross were made to assesses the genetic parameters of 11 quantitative characters of population Created with 16 newly-bred and introduced self-lines. Less affected by environment, characters of ear diameter, cob diameter and keinel row have higher heritability, so early generation selection of these characters would be practical. Character of grain weight per plant, limited by more factors, is lower in heritability and higher in genetic variation coefficient, should be selected in later generation. However, because 79.1% of its genetic variance performed as dominant variance, Combinations with higher Yield and heterosis would be expected from self-lines of the population.
