Grain yield and quality of wheat cultivars – preliminary results from Altinova field trial

Testing of winter wheat cultivars grain yield and quality attributes in comparative field trials is one of the primary steps in determination of genotype suitability for particular growing conditions. With that objective field experiment with seven winter wheat cultivars of Croatian origin (Alka, Katarina, Felix, Renata, Olimpija, Lela and Slavonija-Saray Bosna) and winter wheat cultivar Flamura 85 (Romanian origin), which was used in form of standard, was set up as randomized complete block design (RCBD) in four repetitions at Altinova location (Balikesir Province) in the year 2010. Grain yield, test weight, thousand kernel weight, protein content, wet gluten content, sedimentation value of flour and rheological parameters were measured. Among tested cultivars were found statistically significant differences for grain yield. The highest grain yield achieved cultivars Alka, Flamura 85, Felix and Katarina. The highest average values of test weight showed cultivars Slavonija (Saray Bosna), Flamura 85, Lela and Olimpija while the highest thousand kernel weight were found for cultivars Flamura 85, Olimpija and Renata. Cultivars Felix, Lela and Renata achieved the highest protein and wet gluten content, while only for cultivar Slavonija (Saray Bosna) were found sedimentation value of flour above 60 ml. All cultivars showed medium and good to very good dough rheological parameters.
