Özet:

In this study, 49 advanced lines from local bread wheat landraces that are originated from Denizli, Edirne, Kahramanmaraş and Konya regions of Turkey are compared with 7 selected cultivars regarding to their yields and yield components. Trial is analyzed according to the incomplete block design lattice with two replications with ANOVA and are conducted at Dardanos Agricultural Experimental Station, Çanakkale Onsekiz Mart University, during 2011-2012 growing season. Means are separated by Duncan’s Multiply Range Test and genotype differences are evaluated. Generally and individually, some local bread wheat landrace pure lines are tended to have lesser grain yield, 1000 grain weight, harvest index, grain weight per spike and grain number per spike comparing to the present cultivars while exceeding them over protein content, plant length, number of spikets per spike, lenght of uppermost internode, biomass and spike length. Due to these results, promising wheat landraces that are superior by their grain yield and yield components are chosen as genetic resources to be used in the following bread wheat breeding programs
