Assessment of the collection of potato hybrids under irrigated conditions of the steppe zone of the Southern Urals
Evaluation and selection of breeding material according to the required indicators in the conditions of a specific cultivation zone - occupies the main place in the work on the study of breeding hybrids. The purpose of the study is to identify the best potato hybrids for irrigated conditions in the steppe zone of the Southern Urals from the selection material of the South Ural Research Institute of Gardening and Potato Growing. In the irrigated conditions of the steppe zone of the Southern Urals, a study was carried out to determine the potential for the formation of yield and susceptibility to the main common pathogens in breeding potato hybrids. Of the 19 studied hybrids for 3 years of testing, only 21 % form a yield higher than that of the standard variety, the remaining 79 % are much lower. During the same period, 26 % of the studied hybrids were affected by common pathogens. As a result of the work, a promising potato breeding material was identified for further work, combining low susceptibility with increased yield - Olninsk 13.30.2 (38.1 t/ha), 10.76.1 (60.9 t/ha), M 14.07.08 (38,1 t/ha), М 14.07.6 (51.1 t/ha).
