| Abstract | ||
| Sixty five genotype were selected under gypterous soil condition , in addition to the local varieties (Sham6 and Rabiaa) ,were used to determine the most important characters which can be used as effective selection criteria for grain yield improvement .Phenotypic ,and other compenents characters were determined : plant height ,number of spikes plant spike length number of grain spike and 1000 grain weight ,path coefficient analysis carried out to partition the phenotypic and genotypic correlation coefficients to direct and indirect effects. The results showed that number of spikes and number of grains spike heighty correlated with grain yield .path coefficient analysis indicated that number of spike and number of grain /spike had the most positive direct effect on the yield, so these two character can be used as aselection criteria for grain yield in the gypferous soil | ||
