Grain yield and some yield components of sixteen bread wheat cultivars (Tir, Bezostaja, Gerek-79, Kutluk-94, Kirgiz-95, Suzen-97, Aytin-98, Harmankaya-99, Altay-2000, Dagdas-94, Lancer, Dogu-88, Karasu-90, Palandoken-97, Nenehatun and Alparslan) were determined in this study that were conducted during the 2005-2006 and 2006-2007 growing seasons in Van ecological conditions. Significant differences were determined in grain yield and yield components among wheat cultivars in two years. According to two year average, days to headings ranged between 180.75 (Aytin-98) and 190.62 (Karasu-90) days; grain filling duration, 33.12 (Lancer) - 39.25 (Gerek-79 and Alparslan) days; spike number per m(2), 265.2 (Tir) - 412.2 (Dogu-88), spike lenght, 5.72 (Aytin-98) - 7.27 (Nenehatun) cm; plant height, 66.0 (Harmankaya)- 86.05 (Tir) cm; grain number per spike, 20.32 (Gerek-79) - 27.47 (Harmankaya); grain weight per spike, 0.65 (Alparslan) - 0.93 (Harmankaya) g; thousand grain weight, 29.26 (Aytin-98) - 37.45 (Tir) g; grain yield, 167.07 (Tir) - 238.36 (Dogu-88) kg/da. It was concluded that Dogu-88, Nenehatun and Alparslan bread wheat cultivars were promising cultivars in Van regional conditions.
