The results of studying the collection of vegetable peas (Pisum sativum L.) samples for the resistance to ascochitosis and rust in the south forest-steppe of Western Siberia

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...
