Abstract	Seventeen cultivars of winter rye from the Silesia recommended list were evaluated in post-registration trials at 8 localities in Poland (Wrocikowo, Marianowo, Sulejow, Tomaszow Boleslawiecki, Pokoj, Glodowo, Wyczechy and Lubliniec) in 2000/01. The recently registered population cultivars Wibro, Warko, Motto, Bosmo, Kier, Adar, Walet, Hegro, Zduno, Amilo and Dankowskie Zlote, and the hybrid cultivars Ursus, Nawid, Fernando, Esprit, Luco and Klawo were grown under standard and intensive cultivation. The intensive variant, compared with the standard one, included a higher level of nitrogen fertilization (by 40 kg/ha), application of anti-lodging chemicals, foliar feeding of plants with microelements and complete control of fungal diseases. Statistical analysis for a series of experiments was done based on the computer program Sergen 3. Significant differences in yields and genotype-environment interactions were observed at both variants of cultivation. The hybrid cultivars Ursus, Fernando and Esprit produced the highest yields at both variants. The hybrid cultivar Klawo gave satisfactorily high yield under standard cultivation conditions. The population cultivars of rye gave high yield stability than the hybrid ones, but produced lower yields
