| Abstract | Several factors influence the formation of flowers in temperate fruit species: pomological variety, geographical location, climatic conditions. The leading and decisive role is assigned to pomological varieties, which are a determining factor in the apple production process. The aim of the research was to determine the leading factors of the formation and realization of the productivity of new apple varieties in the soil and climatic conditions of the Steppe of Ukraine. Studies were conducted in 2017-2018. in apple tree plantings, which were located in the garden of FYF "Neophytes" - a branch of the Department of fruit and viticulture of Uman National University of Horticulture. The objects of study were apple varieties: Golden Delicious (control), Gala Mast, Red Chief and King Jonagold, grafted on the rootstock M.9 and planted according to the 3.5 x 1 m scheme. Each variant included 15 plants in quadruplicate. Growth parameters and productivity were determined by the generally accepted method, and statistical processing was performed by the method of variance analysis using computer programs It was established that King Jonagold trees were characterized by the largest diameter trunk. The use of new varieties of apple trees showed that the diameter trunk of the studied plants significantly changed depending on the variety. Thus, the smallest diameter trunk was characterized by the variety Gala Mast, which generally reflects the research of other authors in this variety. Intermediate positions occupied varieties Golden Delicious and Red Chief On average, over the two years of observation, high yields were recorded for the King Jonagold variety. The high commodity indexes of the King Jonagold and Red Chif varieties have been established, which is due to the high resistance to diseases and pests. In general, growth rates had large values for the variety King Jonagold. Intermediate positions in diameter trunk were in the varieties Golden Delicious and Red Chief. Greater yields for the two years of research characterized varieties Golden Delicious and King Jonagold | ||
