Purpose. To study morphoagrobiological and adaptive properties, level of yielding capacity of recently registered soft winter wheat varieties of various ecological groups under agroecological conditions of Kirovohrad variety testing station. Methods. Field study, laboratory test, analytical procedure and statistical evaluation. Results. It was established that the yield level of is a key composite indicator of genotype adaptation to agroecological growing conditions. Experimental data indicate significant deviations of yield depending on the genotype and the year of study. During three years of experiments, yield depending of the variety ranged from 4.26 to 9.71 t/ha, such varieties as ‘CN Kombin’, ‘Estivus’, ‘Tradytsiia odeska’, ‘Mudrist odeska’, ‘Lil’ and ‘Fabius’ had higher yields. In case of dry weather conditions and unfavorable agro-ecological factors, the following varieties as ‘Mudrist odeska’, ‘Veteran’, ‘Lil’, ‘Tsentylivka’, ‘Fabius’, ‘Patras’, ‘Montrei’ have demonstrated good adaptive properties. Their yield has decreased by 9,2–19,0%, while in the varieties ‘Mahistral’, ‘Poltavka’, ‘Harantiia odeska’ and ‘Pokrova’ – by 34.4, 42.4, 45.2 and 50.6% accordingly. Conclusions. Investigated soft winter wheat varieties differ in morphoagrobiological characteristics, productivity, height, maturation period, adaptability as well as economic and agronomic value. According to the complex of such indices as productivity, agronomic characters and properties as well as adaptability, in the microzone of Kirovohrad variety testing station it is advisable to grow varieties ‘CN Kombi’, ‘Pokrova’, ‘Mudrist odeska’, ‘Veteran’ and ‘Lil’.
