Abstract

Odmian, program Sergen, stabilność plonowania, żyto ozime
Seventeen cultivars of winter rye from the Silesia recommended list were evaluated in post-registration trials. The trials were conducted at eight localities: Wrocikowo, Marianowo, Sulejów, Tomaszów Bolesławiecki, Pokój, Głodowo, Wyczechy and Lubliniec in the years 2000–2001. The recently registered population cultivars: Wibro, Warko, Motto, Bosmo, Kier, Adar, Walet, Hegro, Zduno, Amilo and Dańkowskie Złote, and hybrid cultivars: Ursus, Nawid, Fernando, Esprit, Luco and Klawo were grown at two variants of cultivation: standard and intensive. The intensive variant, as 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. The three-year investigations have shown significant differentiation of yields and genotype-environment interactions at both variants of cultivation. The hybrid cultivars: Ursus, Fernando and Esprit produced the highest yields at both variants. The hybrid cv. Klawo proved to give satisfactorily high yield under standard cultivation conditions. The population cultivars of rye were found to be more stable in yielding than the hybrid ones, but produced lower yields.
