Abstract

Seven cultivars of spring wheat were evaluated in post-registration trials in Lower Silesia. The trials were conducted at four sites (Głubczyce, Kobierzyce, Tarnów and Tomaszów Bolesławiecki). The recently registered cultivars: Eta, Jasna, Torka, Helia, Hezja, Nawra and Opatka were grown at two variants of cultivation: standard and intensive. The intensive variant, in comparison with the standard one, differed by a 40 kg/ha higher level of nitrogen fertilisation, application of anti-lodging chemicals, foliar feeding of plants with microelements and complete control of fungal diseases. Statistical analysis was carried out according to computer program Sergen 3. Three-year investigations have shown that the cultivars Jasna and Nawra were the best yieldes Jasna being more stable than Nawra. Torka, a cultivar of excellent baking quality was the poorest yielder of low stability.

Supporting Agencies

The work was carried out as part of the National Post-Registration Variety Experimentation Program coordinated by COBORU.
