摘要

Seventy-seven international winter wheat cultivars and/or breeding lines were grown in the year 2000 in Prishtina, Kosovo to test their adaptation to the local growing conditions. 49 genotypes were selected based on their yield, protein content and extensograph data for further tests in 2001 and 2002. The material was evaluated for yield, 1000 kernel weight, protein content, high molecular weight (HMW) glutenin subunit composition, SDS sedimentation volume, dough mixing and extension characteristics,and baking volume. Principal component analysis was performed on the single years' genotypic means, resulting in nine principal components with an eigenvalue >1.0. The scores of these nine principal components were subjected to Ward's minimum variance clustering method, resulting in three main clusters. The first cluster comprised Austrian winter wheats together with 'Bezostaya 1' and 'Balkan'. This cluster is characterised by high yields, highest 1000-kernel weights, highest protein contents and SDS sedimentation volumes, and excellent dough mixing and extension characteristics. The other two clusters consisted of eastern European genotypes and lines from diverse CIMMYT breeding programs. While the second cluster is characterised by the truly wretched genotypes in regard to both agronomic and quality traits, the third cluster comprises genotypes with highest baking volumes and HMW glutenin subunit scores, and good dough extension traits. It can be summarized that Austrian quality wheats represent avaluable source for winter wheat improvement programs in the Kosovo, especially in regard to quality traits.
