| Abstract | ||
| Twenty tow genotypes of durum wheat in addition to local grown variety(Om Rabee -5) of durum wheat were used in this study. The seeds of the genotypes were sown at research station of plant production, Department of Agricultural Technical College/Mosul-Iraq. In the growing season 2011-2012 using R.C.B.D. design in three replications. The following characters were studied: Number of days to 50% flowering, plant height, spike length, number of grains/spike, number of spikes/m2, biological yield, grain yield, harvest index and1000-grain weight. The results showed that phenotypic and genetic correlations were positive and highly significant between grain yield and each of spike length, number of spikes/m2, biological yield, grain yield and harvest index. Phenotypic and genetic path coefficient analyses revealed that there were high effect of number of grain/spike on grain yield. The selection index included grain yield, number of spikes/m2 and number of grain/spike was superior than other. | ||
