YIELD OF DIFFERENT KAKI CULTIVARS IN THE HUMID SUBTROPICS OF THE RUSSIAN FEDERATION
Kaki persimmon is the main subtropical fruit crop on the Black Sea coast of the Caucasus. The soil and climatic conditions in this territory ensure stable yields, but agroindustrial complex faces the task of constant improvement. The solution to this problem is primarily due to the introduction of high-yielding cultivars into production. The paper presents the results on studying the productivity of some kaki cultivars in the subtropical zone of Krasnodar region. The most productive kaki cultivars are identified and selected to be recommended for cultivation in industrial and amateur gardening (‘Hiakume’, ‘Hachia’, ‘Djiro’, ‘Seedles’, ‘Zenji-Maru’, ‘Hostinsky’ and hybrids № 39 and 99). Among them, ‘Hiakume’, ‘Djiro’ and ‘Hachia’ have the biggest fruits. Fruits quality is marked in the hybrid № 99, which has a sugar content of 22-25 %. The cultivars also differ in their development. The best indicators belong to ‘Djiro’, hybrid number 99, the smallest - to ‘Kiara constant’ and hybrid number 39.
