Sažetak
Information about grain yield and quality of winter wheat cultivars in most important agro- productive environments in each country is of great necessity for breeders, producers and processors of wheat, especially for new cultivars which have been recently released in production. With that aim, field trials with 23 cultivars of winter wheat were set up as RCB design with four repetitions at the five environments-locations (Osijek-eutric cambisol, Tovarnik-cernozem, Pozega-pseudogley, Nova Gradiska and Slavonski Brod-alluvium soil type) during one year (vegetation period 2008/2009). Among 23 wheat cultivars included in this research, 20 cultivars were created at the Agricultural Institute Osijek among which Vulkan, Jana, Aida, Felix, Mihaela, Veronika, Ilirija, Renata, Katarina, Zlata, Seka, Alka, Tihana, Ruzica, Lela, Pipi and Olimpija were recently released (new cultivars), while cultivars Srpanjka, Golubica and Lucija represents approximately 45% of the current Croatian wheat production. Cultivars Sana, Žitarka and Divana were included as standards for grain yield, standard bread quality and improved bread quality, respectively. Grain yield, test weight, 1000 kernel weight, as well as indirect quality traits (protein content, sedimentation value of flour, wet gluten content, gluten index and falling number) were analyzed. For indirect quality traits analysis, average sample of each cultivar per each location was taken. In relation to the other locations, at Osijek location harvest was finished before rainfalls, which have been very frequent at the harvest time in 2009 in Croatia, as well as in some other countries (Slovenia, Hungary, Serbia and Romania) in the region. The highest grain yield (10.050 t ha- 1), test weight (85.21 kg hl-1) and 1000 kernel weight (46.38 g) were realized at the Osijek location, while the lowest grain yield (4.705 t ha-1), test weight (78.20 kg hl-1) and 1000 kernel weight (40.25 g) were achieved at the locations Pozega, Nova Gradiska and Tovarnik, respectively. Over all five environments- locations the highest grain yields were found for cultivars Vulkan (8.720 t ha-1), Jana (8.687 t ha-1), Aida (8.392 t ha-1) and Felix (8.327 t ha-1), what was significantly higher in relation to cultivar Srpanjka (7.831 t ha- 1), which is the most dominant cultivar in wheat production in Republic of Croatia. Although Vulkan, Jana and Aida were most often the most yielding cultivars at all locations, some of the investigated cultivars have responded in a specific manner regarding to the trial locations. In average, over all locations and mostly on each location the lowest grain yield was found for cultivar Divana (5.634 t ha-1). The highest test weight at the all locations was achieved by cultivar Lela. The highest 1000 kernel weight was found for cultivar Ilirija and then for cultivars Mihaela, Renata, Tihana and Zitarka. The lowest test weight and 1000 kernel weight was recorded for cultivars Sana and Vulkan, respectively. According to protein content and sedimentation value of flour in first quality class were aligned cultivars Divana, Zitarka, Olimpija, Golubica, Ruzica and Mihaela, while all other cultivars reached second quality class. Gluten index was varied from 93.2 for cultivar Zitarka to 99.7 for cultivar Alka. The lowest falling number was achieved by cultivar Sana (161), while the highest was obtained with cultivar Mihaela (400). In average per cultivar, wet gluten content was varied from 20.0% for cultivar Jana to 30.1% for cultivar Olimpija. Results of this research are providing valuable information about winter wheat cultivars reaction in different Croatian agro-productive environments and pointed out their adaptability regarding to important agronomic and quality traits.
