The article reflects the results of field research on the study of economic and biological characteristics of varieties and squash hybrids in the conditions of the Right-Bank Forest-Steppe of Ukraine.  A variety and a hybrid with a long fruiting period were identified, namely: a hybrid of Sunny Delight F1 - 77 days and a variety of Zhenechka - 75 days, which is 3 and 1 days long from the control variant.  It was established that the variety Genia and the hybrid Sunny Delight F1 are  haracterized by the largest biometric parameters of plants.  In particular, the number of leaves was: in the variety Zhenechka – 26,2 pcs. / Plant, in hybrid Delny F1 – 27,9 pcs./plant, more than the control version of 4,4 and 6,1 pcs./plant.  The increase in the leaf area relative to the control was at the level of 2,5 thousand m²/ha – in the variety Zheniachka, 3,4 thousand m²/ha – in the Sunny Delight F1 hybrid. The greatest number of fruits was formed by the Sashenka variety and the Sunny Delight F1 hybrid – 17,4 and 19,8 pcs./plant, which is 2.9 and 5.3 pcs. / The plant is larger than the control variant. The largest mass of the fruit was obtained from the Perlinka variety (control) – 285 g, and in the Sunny Delight F1 hybrid this indicator was the smallest and amounted to 235 g, which is 50 g less. In general, according to the experience, varieties were characterized by a greater mass of fruits compared to the hybrid under study, which is associated with the formation of a larger number of fruits on the plant. The same pattern is noted in terms of fetal diameter.  It was the largest in the Pearlka variety (control) – 14,5 cm, the smallest in the Sunny Delight F1 hybrid – 11,5 cm. The highest yield over the years of research was provided by the Sunny Delight F1 hybrid, the increase of which relative to the control was 6,8 t/ha.  Among the varieties, the highest yield was in the Zhenechka variety, where the gain relative to the control was at the level of 2,1 t/ha.
