Abstract
Bu araştırma bazı tritikale çeşitlerinin tane verimi ile bazı verim özellikleri arasındaki ilişkileri, korelasyon ve
path analizi ile tespit edilmesi amaçlanmıştır. Araştırma 2009-10 ve 2010-2011 yıllarında Van ekolojik koşullarında
tesadüf bloklarında bölünen bölünmüş denmeme desenine göre 3 tekerrürlü olarak yürütülmüştür. Materyal olarak
3 çeşit (Karma-2000, Mikham-2002 ve Presto) kullanılmıştır. Elde edilen sonuçlara göre; tane verimi ile biyolojik
verim (0.919**), metrekaredeki başak sayısı (0.429**), 1000 tane ağırlığı (0.129**), başak uzunluğu (0.401**) ve
bitki boyu (0.614**) arasında olumlu ve önemli, başaklanma gün sayısı (-0.356**) arasında ise olumsuz ve önemli
ilişkiler saptanmıştır. Yapılan path analizinde; biyolojik verim (p=0.7493, % 77.46), metrekaredeki başak sayısı
(p=0.1901, % 35.79) ve 1000 tane ağırlığının (p=0.0718, % 26.23) tane verimine en yüksek doğrudan ve olumlu
etki yaptığı belirlenmiştir
This study relations between grain yield and some of the yield characters were determined by means of correlation and path analysis methods in triticale (X Triticosecale Wittmack). The research was conducted between 2009-10 and 2010-11 vegetation periods in Van Ecological condition. The study was designed according to randomized complete block with three replications and three cultivars (Karma-2000, Mikham-2002 ve Presto triticale variety). According to the results; on grain yield biological yield (0.919**), number of spikes per square meter (0.429**),1000-grain weight (0.129**), spike lenght (0.401**) and plant height (0.614**) were significant and positive, while the number of days heading (-0.356**) had significant and negative and relationship. The path analysis indicated that biological yield (p=0.7493, 77.46 % ), number of spikes per square meter (p=0.1901, 35.79 %) and thousand grain weight (p=0.0718, 26.23 %), had the highest and positive direct effect on grain yield it was determined.
