Abstract
- The study was carried out to evaluate yield components and some physiological quality traits for 30 durum wheat landraces(native and foreign originated) and 5 obsolete cultivars in Thrace ecological conditions. Experiments were set up inrandomized block design in 3 replicated during the 3 consecutive growing seasons. As a result of the analysis of variance,the differences between the averages of the genotypes for the traits were found to be statistically significant. This indicatedthat there may be enough variation for traits within landraces. The mean values of genotypes ranged between 2238 kg/ha-1and 3749 kg/ha-1 for grain yield, 98.8 cm and 135.3 cm for plant height, 6.04 cm and 8.88 cm for spike length, 26.6 and35.3 for the number of grains per spike, 0.988 g and 1.494 g for grain weight per spike, 36.1 g and 42.7 g for thousandgrain weight, 74.4 kg/hl-1 and 79.4 kg/hl-1 for test weight and 82.1% and 94.6% for vitreous grain percentage. AlthoughKahramanmaraş, Dicle, Boğacak, Sorgül, Ionia, Cyprus and Haurani were determined as promising populations for yieldand yield components, Siverek, Çanakkale, Tokat, Gaziantep, Yozgat and Urfa landraces had better physical quality. Theestimated coefficient of variation and broad sense heritability shifted from 3.9% to 24.52% and from 7.91% to 72.44%for the traits, respectively. Moderately high coefficient of variation, broad sense heritability a genetic advance for plantheight, spike length and vitreous grain percentage indicated that selection based on these traits will be more effective andaccomplished in the genetic material.
