Determination of yield and some yield components of some registered bread wheat (Triticum aestivum L.) cultivars of Turkey in Mardin - Kýzýltepe conditions | Türkiye'de tescil edilmiþ bazý ekmeklik buðday (Triticum aestivum L.) çeþitlerinin Mardin - Kýzýltepe koþullarýnda verim ve bazý verim özelliklerinin belirlenmesi

إنجليزي. This study was conducted to determine bread wheat cultivars which were grown in Mardin- Kýzýltepe ecological conditions of some important agricultural and plant properties in 2011-12 and 2012- 13 growing seasons. Fifteen braed wheat cultivars (Tosunbey, Bezostaja 1, Ekiz, Pehlivan, Bayraktar 2000, Konya 2002, Doðu 88, Nurkent, Cemre, Karacadað-98, Adana-99, Ceyhan-99, Karatopak, Basribey-95 and Gönen-98) which were officially registered, were used as plant materials in the study. The trial was conducted in randomized complete blocks design with the three replications. The characteristics such as plant height, spike height, numbers of seed per spike, seed yield, harvest index, biological yield and 1 000 kernel weight were investigated in the study. The highest seed yield per area was obtained from Tosunbey variety with 4 305 kg ha-1 in first year, and 4 488 kg ha-1 in the second year, while the lowest seed yield per area was obtained from Bayraktar variety with 2 018 kg ha-1 in 2011-12 growing season and 2 127 kg ha-1 in 2012-13 growing season.

اللغة التركية. Araþtýrma, Mardin-Kýzýltepe koþullarýnda kýþlýk olarak yetiþtirilen ekmeklik buðday çeþitleri ile bunlarýn önemli tarýmsal ve bitkisel özelliklerini belirlemek amacýyla 2011-12 ve 2012-13 yýllarýnda yürütülmüþtür. Denemede Tosunbey, Bezostaja 1, Ekiz, Pehlivan, Bayraktar 2000, Konya 2002, Doðu 88, Nurkent, Cemre, Karacadað-98, Adana-99, Ceyhan-99, Karatopak, Basribey-95 ve Gönen-98 olmak üzere 15 tescilli ekmeklik buðday çeþidi materyal olarak kullanýlmýþtýr. Deneme tesadüf bloklarý deneme desenine göre üç tekrarlamalý olarak yürütülmüþtür. Çalýþmada bitki boyu, baþak boyu, baþakta tane sayýsý, tane verimi, hasat indeksi, biyolojik verim ve bin tane aðýrlýðý özellikleri incelenmiþtir. Bölge þartlarýnda en yüksek tane verimi birinci yýl 430.5 kg/da, ikinci yýl 448.8 kg/da ile Tosunbey çeþidinden elde edilirken, en düþük birim alan tane verimi ise birinci yýl 210.8 kg/da ve ikinci yýl 212.7 kg/da olmak üzere Bayraktar çeþidinden elde edilmiþtir.
