The yield of vegetable peas in Omsk Region is largely lim- ited as a result of the defeat of plant diseases. The purpose of the research was to study a set of peas vegetable samples and identify the varieties resistant to ascochitosis and rust. The objects of the research were 70 samples of vegetable peas from the collections of Federal Scientific Center for Veg- etable Growing (FSCVG), Odintsovo, Federal Research Cen- ter of the All-Russian Institute of Plant Genetic Resources.N.I. Vavilov (VIR), St. Petersburg, as well as obtained through cooperation with foreign selection institutions. The experi- ments were carried out in the forest-steppe zone of Omsk Region in 2014-2017. As a result of the experiments, it was established that ascochitosis affected the peas every year, but with varying intensity, depending on the weather condi- tions. During the researches studied samples were character-ized by average (4.9 points) resistance to the disease. The majority of samples kept high (29 %) and average (48 %) resistance to ascochitosis. There was a tendency to increase the development of rust on vegetable peas, probably due to overcoming of resistance genes. The stability of the samples decreased on average from 7.2 to 3.0 points. In 2014, 100 % of samples had high and medium resistance to rust, and in 2017 only 36 % of samples. As the sources of resistance to diseases for selection of vegetable peas in Western Siberia the samples were allocated: steady against ascochitosis - B- 1295 (to-8907, Bashkiria), Chinese (People's Republic of China), Terass 888 (to-9376, Ukraine); steady against rust - Mezovik, Bondi, Nemchinovsky 46 (to-9518, Moscow Re- gion); with group resistance to two diseases - Id 29600561 (to-9552, Australia).
