The paper presents the results of ecological testing of pea varieties of various origins. The studies were carried out in 2015–2018 on the vegetable field of the Far Eastern Agriculture Research Institute. The objects of the research were pea varieties of various ecological and geographical origin. Promising lines and varieties were created and provided by the Federal Scientific Center of Legumes and Groat Crops (lines L-102-07, L-104-13, L-75-06, L-20-03 with sarmentose leaf type, variety Spartak and lines YaG-09-523, YaG-07-652, YaG-07-643, YaG-07-599, YaG-06-83, YaG-08-1269, R-743-09 with longline heterophilia) and the Ulyanovsk Research Institute of Agriculture (leaf variety Ulyanovets, sarmentose varieties Ukaz and Yubilyar). The standard was the variety Aksaiskii usatyi 55. All studied varieties are characterized as mid-ripening, the growing season was 74–77 days with a variability range from 12 to 20 days. The weather conditions had the greatest influence on the duration of the germination-flowering period, while the temperature regime was more significant. A positive relationship was found between the duration of the entire growing season and the duration of the period from mass flowering to ripening (the correlation coefficient reached 0.63±0.05). The maximum yield over the years of research was formed in thestandard variety Aksajskij usatyj 55 (26.7 c/ha) with an average yield of 23.3 c/ha. A high dependence of pea yield on hydrothermal conditions during the growing season was revealed. It has been established that it is the temperature factor in the conditions of the Middle Priamurye that has a negative impact on the formation of the crop. As a result of the research, the samples Aksajskij usatyj 55, YaG-06-83, YaG-08-1269 were selected, which had the shortest growing season in the study group. The varieties P-743-09 and Yubilyar had the minimum duration of the period from germination to mass flowering and the number of nodes up to first pod. Selected variety samples can be used in breeding early-ripening pea varieties for the Middle Priamurye.
