| Abstract | ||
| This research was conducted using Augmented Experimental Design during 2015-2016 growing season in Konya and Kirkuk conditions. 17genotype materials (12 lines and 5 check genotypes of durum wheat) obtained from different sources were used by which yield and some of yield characteristic were analyzed in Turkey and Iraq locations. The durum wheat lines in this study were pure and stable. Observations and measurements related to plant height, spike length, number of grains head, harvest index, thousand grains weight and grain yield were recorded. According to the research results, changes in the characteristics varied based on the genotype and locations. Average values observed for check durum wheat genotypes and durum wheat lines at Konya Location were 101.8 cm and 108.7 cm for plant height,6.99 cm and 8.10 cm for spike length, 51.16 pieces and 42.24 pieces for number of grains in head,50.89 g and 53.45 g for thousand grains weight, 30.63% and 23.48%for harvest indexand 3.963 ton/ha and 3.494 ton/ha for grain yield. At Kirkuk location, these average values for the check durum wheat genotypes and durum wheat lines respectively were 116.61 cm and 119.15 cm for plant height, 9.25 cm and 9.59 cm for spike length,47.31 pieces and 42.45 pieces for number of grains in head, 37.64% and 38.79%for harvest index,44.55 g and 48.49 g for thousand grains weight and 3.339 ton/ha and 3.749 ton/ha for grain yield. In general, at Konya location the check durum wheat genotypes and durum wheat lines for plant height, spike length and harvest index wear showed low level of values, either in Kirkuk there was a significant difference in values. while the thousand grain weight increased at Konya location. The number of grains in head did not show significant in both locations for durum wheat lines,while the genotypes found a significant difference compared to the location of Kirkuk .Durum wheat lines and check durum wheat genotype reactions with respect to grain yield showed difference according to the locations. While average yield of the durum wheat lines was found to be lower at the rate of 6.8% compared to Kirkuk location, average yield values for check durum wheat genotypes were found to be higher at the rate of 15.76% at Konya location compared to Kirkuk location. It was observed from the average values of the check durum wheat genotypes that Umrabi had the highest value appeared, for durum wheat lines one of the superior was AT-060had the highest value appeared as well as 060,5020-7 and Gir at Kirkuk location. Ether in location of Konya for check durum wheat genotypes was Kunduru-1149had the highest value appeared, for durum wheat lines wasAT-061 had the highest value appeared. This situation revealed that check durum wheat genotypes being different from the durum wheat lines showed positive reaction to the regions in which they were registered with respect to yield. | ||
