Abstract
Basing on the results of an experiment with winter wheat varieties and strains, carried out in the years 1991–2000 as so called working collection, groups of forms being potential source of yield and 14 agronomic traits for breeding programmes were characterized. The forms of the most valuable traits under study were listed, especially those which combined several valuable traits. The varieties and strains currently investigated in the experiment can serve as a good source of yield and yield parameters, resistance to lodging and brown rust, and also sedimentation value. As far as the remained traits are concerned, there is a need to search for or even to generate new sources of the resistance to powdery mildew and ear septoria, resistance to pre-harvest sprouting, grain protein content, and especially resistance to frost and leaf septoria.
