Sažetak
Quantitative traits are results of genotype, environment and their interactions. With purpose of obtaining information about winter wheat genotypes reaction in different environmental conditions during 2006./07., trials with twenty four winter wheat genotypes, two seeding rates (SN) 600 and 300 kernels/m2 and four repetitions, were set up according to RCB scheme on four locations with different soil types (Osijek-eutric cambisol, Tovarnik-cernozem, Nova Gradiska-alluvium and Pozega-pseudogley). Grain yield, thousand kernel weight, test weight and protein content were analyzed. Statistically highly significant differences for all traits were found among genotypes (G), locations (L), sowing rates (SN) and for interactions GxL and LxSN, while interaction GxL was highly significant only for test weight. In both seeding rates the highest grain yield (78, 79 dt/ha ; 73, 05 dt/ha) and test weight (82, 11 kg/hl ; 81, 75 kg/hl), but accompanied by the lowest protein content, (11, 36% ; 11, 27%) were realized at Tovarnik location. The lowest grain yield in 600 kernels/m2 seeding rate with the highest protein content in both seeding rates (14, 09% ; 14, 35%) were realized at Osijek location, while the lowest grain yield in reduced seeding rate at Nova Gradiska location were accompanied by the highest 1000 kernels weights in both seeding rates. The lowest test and 1000 kernels weight in both seeding rates were found at Požega location. The most yielding genotypes were Lucija, Osk. 48/07, Zlata, Srpanjka, Renata, Alka and Felix. The highest test weight were achieved genotypes Felix, Lela, Osk. 63/05, Renata, Pipi, Super Žitarka and Janica, while highest 1000 kernels weight were reached genotypes Osk. 63/05, Super Žitarka, Renata, Divana, Felix and Osk. 64/05. Genotypes Divana, Golubica, Žitarka, Osk. 63/05, Osk. 77/05, Ficko and Osk. 64/05 were realized the highest protein content. In 600 kernels/m2 seeding rate higher grain yield and test weight were realized. In general, tendency of higher protein content coupled with lower 1000 kernels weight was observed at seeding rate with 600 kernels/m2 in relation to reduced seeding rate for most genotypes, but specific reactions of particular genotypes also were found.
