In this study, 42 bread wheat pure lines obtained from 340 landraces, collected from 35 provinces of 7 regions inTurkey, and 7 modern bread wheat cultivars were evaluated under rainfed conditions in Konya, in 2005-2006 and 2006- 2007 growing seasons. Experiments were conducted in a 7 × 7 lattice design in 3 replicates. Both genotype-traits (GT)biplot analysis and path analysis were used to investigate the relationships between grain yield and 12 traits. Applyingboth types of analyses to the multiple traits data revealed that GT biplot graphically displayed the interrelationships amongtraits (breeding objectives), identii ed traits that are positively or negatively associated, and facilitated visual comparisontrait proi les (strength and weakness) of genotypes, which is important for parent as well as variety selection. Vastvariations existed in traits (number of grains $m^ {-2}$ , harvest index, number of spikes $m^ {-2}$ , number of grains spik$e^ {-2}$ , andweight of grains spike-1and biological yield) and grain yield. It was found that either pure lines or cultivars with thehighest grain yield had the highest biological yield, number of grain $m^ {-2}$ , and harvest index. The results showed that purelines combined with favorable traits G43 (Kars-TR15796-7), G33 (Kars-TR15796-4), G20 (Kütahya-TR55167-3), andG11 (Kütahya-TR55212-4) can be evaluated in multi-environment trials for a candidate winter bread wheat registrationtrial. Some pure lines that had high quality traits G26 (Samsun-TR37926-3), G45 (Erzurum-TR32881-6) and G49(Erzurum-TR32668-1) might be good parents for enhancing quality in bread wheat. In conclusion, for the short-termimprovement of Turkish bread wheat landraces may be possible through an indirect selection of the number of grain m-2 and biological yield, or direct selection for grain yield per se. In the long-run, crossing programs between indigenousand introduced exotic germplasm may be necessary for high industrial quality characters of bread wheat.
