Diversita evropských krajových odrůd ozimé pšenice a jejich potenciál pro šlechtění.

Original language description

Landraces and obsolete cultivars (120 accessions) were evaluated in three-year field trials. Among the 13 examined characters, a relatively wide diversity (C.V. over 10%) has been estimated in spike length, characters of spike productivity (except in grain weight) and some quality characters (SDS-test and especially Gluten Index). Lower spike productivity and good grain quality were characteristic for cultivars originating in the southeast whereas cultivars from northwest Europe showed an opposite tendency and were late. Most of landraces and obsolete cultivars from North-East and North Europe proved also good winterhardiness. Valuable resources can be found in grain quality characters. Genetic heterogeneity has been characterized using analyses of glutenins by SDS PAGE. Only few accessions were homogeneous, most of them consist of two or more protein lines. The frequent HMW-GS alleles at the Glu ?A1, Glu-B1 and Glu-D1 loci were 1, 7+9, 2+12, however, also rare allelic combinations wer
