This research was done in the Agricultural Scientific Research Center in Homs during two seasons 2004 – 2005. The aim of this research was to study the effect of the selection of the protein on the yield characters of maize families population-2 (45). They were selected from the maize population -2 and divided into three groups as follows. The first group had low protein value from 5–7%. The second group had middle protein value from 7 - 9%. The third group had high protein value more than 9%. The analysis of variance (ANOVA) showed significant differences between those families for yield characteristics. The characters (plant length and ear height) showed negative correlation with protein (ear length, number of ear rows) and positive correlation with protein value; while (tassel number brunches, leaf area index) showed negative correlation with protein. The weight 1000 seeds, weight seeds in ear, number seeds in ear) showed negative correlation with protein. Group1 was the most responsive to protein genetic development (%75.39) then group2 (%40.80) and group3 (%7).
