Determination of inheritance of some yield and quality traits in winter wheat (triticum aestivum l.)

Abstract

This study was carried out in Uludag University Agriculture Faculty Research and Application Center between years of 2000–2002 to determine of inheritance of some yield and quality traits in winter wheat. In this reseach, involving 6 x 6 diallel cross without reciprocals, seed number/spike, seed weight/spike, 1000 kernel weight, protein and gluten content were investigated over F1 plants and parents. According to the results of diallel analysis, additive and dominance gene variances were found for gluten content, dominance variance was determined for seed number and weight per spike, 1000 kernel weight and protein content. In Wr-Vr graphs about parents, was observed partial domiance in gluten content and over dominance in the other traits. Narrow and broad heritability sense ranged between in respect of 0.019–0.705 and 0.469–0.961 in investigated traits. The highest heritability was determined in gluten content (0.705–0.961) and concluded that effective selections can be done in early generations. © 2004 Taylor and Francis Group, LLC.
