Abstract

Nine cultivars of winter barley were evaluated in post-registration trials in Lower Silesia. The trials were conducted at five sites (Głubczyce, Krościna Mała, Pawłowice k/Wrocławia, Tarnów and Tomaszów Bolesławiecki) in the years 1999-2001. The recently registered cultivars: Borwina, Gil, Gregor, Horus, Kos, Kroton, Sigra, Tiffany and Tramp 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 the computer program Sergen 3 for a series of experiments. The three-years investigation has shown a significant differentiation of yields and genotype × environments interaction in the both variants of cultivation. The cultivars Gregor and Gil were the best yielder, but with of low stability of the yields.
