Evaluation of entered durum wheat (Triticum durum) genotypes under middle conditions of Iraq

Abstract

Field experiment carried out in the seasons 2011/2012 and 2012/2013 in Abu Ghraib Research Station/ Agricultural Research Office. Experiment included 16 genetic entrance from ICARDA in addition to the local variety (D7) for comparison. Treatments were distributed in (RCBD) design with three replications. Significant differences were observed among all genotypes and studied traits. ICARDA-14 and local variety, gave higher values (84 and 85.11 cm) for plant height, local variety and ICARDA -16 (9.5 and 8.940 cm) for spike length, ICARDA-8 and 12 (20.57 and 20.5) for spikelet number/spike, ICARDA-9 and 16, (70.2 and 66.32) for grain number/sike, ICARDA -6 and 2 gave highest weight of 1000 seed, (41.18 and 38.76 g), while ICARDA -12 and 3 were superior in spikes number/m2 (527.5 and 490.2), grain greater for ICARDA -12 and 3 (5.187 and 4.787 t / h). The highest biological yield was for each ICARDA-1 and the local variety, which were superior in dry weight also (19.95 and 17.61 t / ha) but the highest harvesting index was for ICARDA-8 (38.06 and 35.32%) in both seasons, respectively.
