Özet:

 


The aim of this study was to investigate gene effects and genetic variability by generation mean analysis for some yield and quality traits in two winter wheat crosses (Pehlivan × Bezostaja and Sana × Krasunia). The parents and F1, F2, BC1, and BC2 populations were grown in a randomized complete block design with three replications during the 2008-2009 crop seasons. A three parameter model was not sufficient to explain variation for most traits in generation means. The additive-dominance model was adequate for plant height, grain number per spike and grain weight per spike in the Pehlivan × Bezostaja-1 cross, and for grain weight per spike and all quality traits in the Sana × Krasunia cross. The scaling test revealed that epistasis had a predominant role in the expression of all traits except grain yield, protein content and gluten index in the Pehlivan × Bezostaja-1 cross, and spike length and grain yield in the Sana × Krasunia cross. Dominance effects and dominance × dominance epistasis were more important than additive effects and other epistatic components. All traits which had significant epistatic gene effects showed duplicate type epistasis. Therefore, early generation selection would fail.
