“…In a scientifically based technological system for the cultivation of agricultural plants, breeding and seed production occupy a leading position as the most powerful, environmentally friendly levers in increasing the yield and quality of crop products [3]. According to available estimates, the contribution of breeding to increasing crop yields over the past decades is estimated at 30-70%, and taking into account possible climate changes, the role of breeding will increase [4,5].…”

In solving the issues of modern rice growing, the central place is occupied by development of new varieties and their timely introduction into production. The assortment of rice varieties of Kuban breeding is annually replenished with more productive ones with increased resistance to adverse biotic, abiotic and anthropogenic factors, with different culinary qualities. The yield of the variety is one of the main indicators of value and the main requirement of production. This article presents the results of ecological variety testing of 20 rice varieties over three years (2016-2018) on the territory of private company "Rice" in Republic of Adygea. The variability of yield and the number of productive stems per unit area are determined for every variety. The average and weak intervarietal variability of productive crop density (13.9%; 10.3% and 13.5%) and yield (12.4%; 9.2% and 9.9%) during the study period is associated with the level of agricultural technology of the farm. Varieties of Krasnodar breeding: Polevik, Patriot, Favorit, Apollon, Veles, as well as foreign ones-Galla (Italy) and Yatkyn (Turkey), which formed a significantly high yield with its insignificant variability, are recommended for cultivation in "Rice" company (Republic of Adygea).
