Description
Summary:The chemical composition and the dry matter yield of the whole plant of 18 winter barley (Hordeum vulgare L.)cultivars grown at five locations were examined to evaluate the feasibility of developing a breeding programme for silage.Differences among cultivars,locations and their interactions were found for all traits.The locations were the largest source of variation,whereas interactions were small except for crude fibre. Heritability estimates (broad sense) were high for protein, ether extract and ash content,but very low for fibre content. Data of this study indicated that genetic variability among cultivars for the main quality traits was small and consequently the manipulation by selection from the material considered would likely be ineffective.
