Abstract

Aim. Research and give comparative assessment of modern bread winter wheat varieties of different gene pool accessions from different originating institutions on some backgrounds of mineral fertilizers and identify universal varieties that will provide high yield potential with different growing technologies. 

Results and Discussion. Vozdvizhenka and Okhtyrchanka yuvileina stood out, against the background without fertilizers. Their average yield are 6.09 t/ha and 6.05 t/ha, respectively, Peremoha – 5.75 t/ha, Haiok – 6.39 t/ha. On fertilized background, Peremoha variety was the most productive – 6.38 t/ha, Zdobna variety, which averaged 6.54 t/ha, which is 0.59 t/ha (10%) more than the Bohdana variety. Significant yield increase was also obtained in Haiok varieties – 0.33 t/ha (6%) and Harmonika – 0.25 t/ha (4%).

Conclusions. It was found that yield potential of new varieties of winter bread wheat was significantly higher than that most common Bohdana variety in Ukraine. The tested varieties Vozdvizhenka, Okhtyrchanka yuvileina and Svitankova provided high yield increase only against an unfertilized background. Whereas the varieties Zdobna and Haiok, as well as Peremoha, showed high yield potential on both fertilizer backgrounds, which indicates their versatility and makes it possible to grow these varieties in farms with different levels of soil nutrition and resource provision.
