The results of studying the collection of foreign ornamental varieties of chaenomeles (Chaenomeles Lindl.) of two species are presented: Ch. speciosa (Sweet) Nakai and Ch. japonica (Thunb.) Lindl. et Spach. and two hybrid groups: Ch.×superba (Frahm) Rehder., Ch.× californica W. Clarke ex C. Weber, preserved at the Krymsk EBS � branch of VIR, and in a private collection in the Republic of Adygea. Valuable physiological features were determined: the timing, degree and duration of the flowering period in the conditions of the northwestern piedmont of the Main Caucasian Range. The characteristics of 25 varieties of chaenomeles are given in terms of color, diameter and degree of doubleness of the flower, parameters of the bush, characterizing the decorativeness of its plants, which will expand the range of flowering shrubs for landscaping city parks and squares. Four varieties with the largest double flowers (53 to 65 mm in diameter) were identified: Kinshiden, Scarlet Storm, Mango Storm, Pink Storm, and two varieties with a high degree of doubleness � Pink Storm and Orange Storm, the flowers of which have more than 30 petals. A clear palette of corolla color of the studied varieties was determined: from white to dark red with various shades, including pink and orange. According to the habit of the bush, the varieties are divided into three groups: eight varieties are tall (above 150 cm), three are low-growing (100 cm on average) and the remaining 14 are medium-sized. It has been established that all the studied varieties are suitable for wide use in landscape construction in the Kuban. As sources for targeted breeding programs, varieties with the highest decorative effect � a large double flower of various colors are recommended: Kinshiden, Jet Trail, Wakaba and varieties of the Storm group.
