Özet
This study was conducted to investigate yield and some agronomic traits of 10 regisreted barley cultivars (Hordeum vulgare L.) in Turkey in rainfall and supplemented irrigation conditions during 2011-12 and 2012-13 growing seasons at Diyarbakir/Cinar, Turkey. Experiments were arranged according to Completely Randomized Block Design with four replications. Obtained data was evaluated with variance analysis and GGE biplot method. Also, the barley cultivars were evaluated regarding to drought tolerance indices. According to mean of two years data grain yield of cultivars ranged from 417 to 578 kg/da in supplemented irrigation condition and from 281 to 391 kg/da in rainfall condition, while the mean of invastigated traits in supplemented irrigation and rainfal condition were 41 g and 38 g for 1000 kernel weight, 68 kg/hl and 62 kg/hl for test weight, 513 adet/m(2) and 367 adet/m(2) for number of spikes in sequmeter respectively. According to GGE biplot results G3 and G5 was determined as most stabil cultivars for grain yield. The highest grain yield was obtained in G3, G9, G5 and G10 for mean of the supplemented and rainfall conditions respectively (irrigation condition: 578; 533; 520; 550 kg/da, rainfall condition: 363; 365; 391 ve 363 kg/da). According to GGE biplot G9 is suitable for rainfall condition and G3 for irrigation condition. It was determined that YI (Yield index), was related to grain yield in rainfall condition, thus this parameter could be used in breeding programs to determine drought tolerance genotypes. The other drought tolerance indices such as HM (Harmonic Mean), GMP (Geometric Mean Productivity), STI (Stress tolerance index), MP (Mean productivity) and TOL (Tolerance) were related to grain yield in irrigation condition, so these parameters can be used to determine genotypes that suitable for irrigaton condition.
