Abstract
Thirteen local and entries tetraploid genotypes of durum wheat (Triticum durum Desf.) were planted at Izra’a Station (Dar’a Centre), General Commission for Scientific Agricultural Research GCSAR, during three seasons (2013/2014, 2014/2015 and 2015/2016) under rainfed conditions, in addition to the local variety Sham3 as a check in a Randomized Complete Block Design RCBD with three replications. The studied traits were (days to maturity, plant height, spike number per plant, spike length, weight of grain per spike, weight of thousand grains and individual plant grain yield) in order to evaluate the variance between genotypes and seasons and the interaction between them, and to define the superior genotypes to provide them to the breeding programs. Results showed that the genotype wheat1527 was significantly superior in spike length, grain weight per spike, thousand grains weight, and individual plant grain in a rate of 36.92, 32.10, 21.43 and 36.47% respectively, compared to the check variety Sham3. Results also showed that the genotype wheat 1471 was significantly superior in spike number in a rate of 23.07% comparing to the check Sham3 as the number of spikes in plant was (10.67, 8.67) for each of them respectively. Each of plant grain yield, spike length, spike number per plant and days to maturity were all significantly superior during the season 2016 comparing to both seasons 2014 and 2015.
Key words: Genotypes, Durum wheat, Grain yield.
