In this article were presented the results of research carried out in the southern forest-steppe zone of Omsk region in 2016-2018. This research was devoted to the creation of new varieties of peas sowing leafless morphotype with high productivity and improved product quality. There were tested 189 samples of peas in four-fold repetition for three years, which also included registered varieties of local and foreign selection, new perspective lines created in the Omsk SARC. Technological quality of grain of peas is estimated at 160 accessions – 1760 conducted analyses of 11 indicators. The studies were carried out with the use of verified instruments and equipment in accordance with the state Commission methodology, as well as with the methods adjusted in the laboratory of grain quality. In this article is also presented the characteristic of the most valuable breeding lines on the main indicators of grain quality and productivity. There is given considerable emphasis to the problem of protein and the effect of weather conditions on its share in the pea’s grain. It is confirmed that the variability of the amount of protein largely depends on the environmental conditions – with an increase in hydrothermic coefficient: in July (the phase of flowering), the proportion of protein increases (r = 0,94), and in August (the period of filling and ripening of beans) – decreases (r = -0,97). There was no significant correlation between the yield of seeds and their protein content, but the collection of protein per hectare primarily depends on the yield (r = 0,90). As a result of research created breed of peas with a leafless type “Triumph of Siberia” of the grain-growing direction and transferred to the State variety testing in the Russian Federation in 2018. According to the protein content in the grain and the yield of cereals are attributable to the requirements of the State Commission for valuable varieties
