Abstract
The work presents the results of evaluation of 150 varieties of sowing peas (Pisum Sativum L.) of different ecological and geographical origin that have not lost their breeding value in recent years by a number of economically valuable signs from the world collection of The N.I. Vavilov All Russian Institute of Plant Genetic Resources. The purpose of the research was to identify promising varieties of sowing peas from the collection to create modern varieties of peas for grain use. The experiment was conducted in 2014–2016. on leached chernozem of the northern foreststeppe of Western Siberia. The weather conditions during the years of research were contrasting. So, in May and July of 2014, precipitation was above the average rainfall, which caused the formation of tall pea plants, especially in the varieties of leafy morphotype. In 2015, the air temperature was above the long-term average annual rate with uneven precipitation. In 2016, the air temperature in May generally corresponded to the long-term average annual rates, but August was characterized by precipitation deficit. The maximum yield for the years of research was noted in the varieties of leafy morphotype group: Bogatyr (625 g/m2), Kemchug (510 g/m2), and the group with the modified morphotype: Az-318 and Orel (480 g/ m2). Varieties with the modified morphotype Az-318, Sprut-2, Orel, Demos, Yamal proved to be highly resistant to lodging and easy to harvest, due to being adapted to the soil and climatic conditions of Western Siberia. The correlation analysis conducted in 2016 revealed a reliable positive relationship (r = 0.63) between the mass of 1000 grains and the yield. A closer positive relationship was found during all the years of the study between the yield and the number of peapods on the plant (r = 0.48–0.67). A negative dependence was observed between the length of the plant and the yield.
