Palamarchuk Inna Ivanivna – Candidate of Agricultural Sciences, Senior Lecturer of the department of landscape gardeniing, horticulture and viticulture of the Vinnytsia National Agrarian University (21008, Vinnytsia, Solnyschaya St. 3,e-mail: pal_inna@vsau.vin.ua).

The results of studies on the study of the formation of the yield of the fruits of the patisson in relation to varietal features and weather conditions during the years of experimental work are presented. Priority concomitant studies were phenological observations, biometric measurements of plants and fruits. It is proved that the investigated varieties and the hybrid in the Forest-Steppe of the Right-bank are among the early ripening. The interphase period "mass shoots – the beginning of technical ripeness" in all varieties lasted 42 days, and in the hybrid Sunny Delight F1 – 41 days. The long fruiting period was characterized by a hybrid of Sunny Delight F1 – 66 days. According to the research, it was found that the duration of the growing season in the varieties and hybrid studied was 109 days – in Perlynka and Sashenka varieties, 108 days in the Zhenichka variety and the Sunny Delight F1 hybrid.

The largest length of the stem was the plants of the Sunny Delight F1 hybrid 78,4 cm, which is 10,6 cm more than the control. The investigated hybrid was characterized also by the largest leaf area – 12,4 thousand m2/ha, which is 3,0 thousand m2/ha more control. The most fruitful were the Sunny Delight F1 hybrid and the Zhenichka variety, they generated a commodity yield of 39,7 and 35,0 t/ha, that they were 6,7– 2,0 t/ha, respectively, from the control variant. The largest number of fruits formed the plants of the patisson of the Sunny Delight F1 hybrid – 15,5 pcs/plant, which is 4,8 pcs/plant more control. Less fruit was Perlynka (control) plants – 10,7 pieces/plant, but this variant was characterized by the largest fetal weight – 266 g. All other variants had somewhat smaller in weight fruits.

The level of natural water availability affects the yield of the fruits of the patisson. According to the State Customs Committee, in 2016 and 2017, were arid, but in 2017 precipitation increased by 43 mm, which contributed to a 1,6–2,1 t/ha increase in the yield.
