Abstract
It was revealed that the fruits of the hybrid forms of peach were better tied and preserved on the main shoots of the first wave of growth. To a lesser extent, the formation of the ovary occurred on thin, weak secondary growths and on old bouquet branches. Three periods of fruit growth of hybrid forms were marked, which are characteristic of other peach varieties. Of the 42 studied forms, 48 % (19 hybrids) were noted with an early maturity, 38 % (15) with an average maturity and 14 % (5) with a late maturity. Two forms with very early ripening and one form with late fruit ripening were marked, which are promising for use in breeding.

Summary
Многие исследователи различают три периода роста плодов персика. Во второй период роста плодов размер их не увеличивается так заметно, как в первый и третий, но постоянно нарастает количество сухого вещества. Целью исследования являлось изучение особенностей образования, роста и сроков созревания плодов гибридных форм персика селекции Никитского ботанического сада. Объекты исследования — 42 гибридные формы персика, перспективные для дальнейшей селекции, а также три контрольных районированных сорта: раннего срока созревания –Пушистый Ранний, среднего срока — Красная Девица, позднего срока — Крымская Осень.
