Abstract
The purpose. To analyze influence of different factors upon productivity of new grades of winter wheat in conditions of South Forest-Steppe of Ukraine. Methods. Measuring-weight, statistical, dispersion and regression. Results. All probed grades were characterized by high productivity at seeding 5,5 million seeds/hectare on October, 5. Three factors: year of growing (49,4%), genetic potential of the grade (34,4) and seeding rate (7,4%) totally form 91,4% of grain yield of winter wheat of the probed grades at growing in conditions of South Forest-Steppe. The highest level of productivity of seeds for years of researches has ensured the grade Astarta (9,36 t/hectare), and the least — the standard grade Bogdana in the best alternative (5,55 t/hectare).

Key words: grade, wheat, factor, Astarta, Bordana, rate, time, method of sowing.
