| Abstract | ||
| Astudy was conducted for evaluating of performance and . estimating of som genetic parametera and selection index for nine genotypes of double row and aloccal variety of barley crop – Seeds of these genotypes had been planted in two locations , first in fields of Agrioaltore college / Tikrit U niversity , other in Tuz location at winter season of 2010 – 2011 by using R.C .B. D with three Replicates . Characters of grain yield (GY) efficiency of metabolism (NET). Refative growth ratio (RGR) leaf area ratio (LRA) duration of maximum standing leaf eara (LAD) efficiency of the yield spikes . density/m2, number of spike seeds , weigh of 1000 grains , plant height and harvest index were studied , the results showed as Highly signi , ficant differences were appeared between genotypes for all studied traits , the genotype (CWB 117-77-9-7/ICB-104073 // Abiath arabi) Was saperion in grain yield , efficiency of (GY) , (NET) , (RGR) , weigth of 1000 grains and harvest index in college location . The genetic variation was signiffcant in both two locations for all studied traits except duration of maximum leaf aera in college location . High value of broad sense heretability was occurred in grains yield , relative growth rate , ratio of leaf aera , efficieany of yield , spikes density and number of spike seeds , reflected on expected genetic advance parameter. High relative efficiency was occurred in selection index including gratrs yield , ratio of area and duration of maximum leaf area standing traits in college location , while grains yield , efficieny of metabolism , relative growth rate and duration of maximum leaf area standing were in Tuz location , the genotype (CWB 117-77-9-7/ICB-104073 // Abiath arabi) was superior in both tow location . | ||
