| Abstract | ||
| Six pure lines of Corn were used in this study (SH ,IK8 ,IK58 ,OH40 ,UN44052 and ZP105 ) with it, s half dialled crosses and two crosses of control (local shahed and introduced ZP600 ) planted in the field of one farmer in Baiji prince – Salahelden Government through Autumn season 2013 in three environments by dependent experiments kept with distances between holls ( 15 cm , 20 cm and 25 cm ) by using R.C.B.D. with three replication . Data were recorded on traits of male and female flowering dates, plant height,uper ear height ,leaf area, Ear length, Number of ear rows, number of row grains, weight of 300 grains, single plant yield and ratios of oil and protein .The results showed surpassed of third environment in trait of number of row grains , single plant yield and protein ratio , and first environment for oil ratio , the hybrid (SH X ZP105) was surpassed in traits of number of row grains (44.16) grains , weight of 300 grains (99.12) gm and single plant yield (210.77) gm , and the hybrid (IK58 X ZP105) in traits of leaf area (4290.1) cm2 and number of ear rows (16.02) row and oil ratio (7.29%) . The phenotypic and genetic environment variance were differed about zero the genetic variance was more than from environment variance , the heritability of broad sense was high for all the studied traits . The single plant yield was correlated as a genetic and environment correlation with high significant with traits of leaf area, number of ear rows, number of row grains and weight of 300 grains. This result agreed with results of significant Regression treatment of these traits on yield of single plants , and some hybrid were surpassed in higher mean with broad stability as hybrid (SH X ZP105) which gave the first stage as FW,SH, and ER indexes in number of row grains trait , and the FW and SH indexes for Single plant yield trait , the hybrid (IK58 X ZP105) which was surpassed in two traits of leaf area and number of ear rows , which also took first stage as indexes of FW , SH and ER . | ||
