| Abstract | ||
| A field experiment was conducted in college of agriculture field during 2012-2013 season , A randomized complete block design in a split plot design with six varieties ( Tamoz 2 , Tamoz 3 , IPA 99 , IPA 95 , Abu-Ghraib 3 and AL-Rashed ) as sub plots and three seeding rates ( 80 , 160 , 240 ) Kgha as main plots with three replication .Genotypic , phenotypic variances and coefficient of variability , broad sense heritability percentage and expected genetic advance .Data recorded on flag leaf area.plant height.number of spikes per m2.number of grains per spike.1000 grain weight and grains yield.Significant differences were found among wheat varieties. seeding rates and the interaction except flag leaf area. Tamoz -3 was superior at240 kg/ha in grains yield. The results showed that genotypic variances and coefficients of variability were varied with seeding rates genotypic variances more than Ecological variances for all characters . phenotypic variance coefficient was more than genotypic variance coefficient for all characters . The higher values for broad sense heritability appeared in number of grainsspike , 1000 grain weight and grain yield. The medium value for expected genetic appeared in number of spikes m2 and grain yield . | ||
