Abstract

The results of biometric indicators of growth, features of the passage of the main phenological phases of development, analysis of precocity, yield and commercial qualities of fruits of various plum varieties are presented. The studies were carried out on the irrigated plot of the orchard of the Federal State Budgetary Scientific Institution "Caspian Agrarian Federal Scientific Center of the Russian Academy of Sciences", which was founded in 1993. The difficult climatic conditions of the region require the selection of varieties, first of all, with increased adaptive potential. As a result of the research, it was found that the Renklod Altana (3.1 m) and Mechta (3.1 m) varieties had the highest tree height. All studied varieties began to bear fruit in the 3rd year. Stable fruiting was observed in all varieties in the 5th year of vegetation. The highest yield was obtained in the variety Tatyana - 8.6 kg/tree.
