The results of assessment of pea varieties in a competitive varietal test under conditions of Kirov region (Volga-Vyatka economic region) on productivity of grain, green matter and hay are presented. An object under re-search - 21 pea varieties of different morphotype bred in Falenki breeding station. Meteorological conditions for years of research (2014-2017) differed significantly in temperature regime and the amount of precipitation: favora-ble conditions for pea vegetation were in 2014 and 2015, the adverse ones - in 2016 and 2017. In group of grain-hay white-flowered plants variety Falensky yubileiny was selected. It had an average yield of grain – 4.1 t/ha, green matter – 34.3 t/ha, hay – 4.4 t/ha that exceeded standard variety Krasnoufimsky 93 by 0.7, 9.0 and 0.8 t/ha respectively. Among grain-hay color-flowered plants the perspective line D-24746 (productivity of grain – 4.0 t/ha; green matter – 35.3 t/ha, hay – 5.5 t/ha) exceeded standard variety Ryabchik by 0.6, 5.3 and 1.3 t/ha respectively. The varieties were defined which exceeded standards by grain productivity (Vita, D-22477, E-3542, D-22596, E-630, E-626, E-460, E-3698), green matter (E-3583, E-411, D-22596), and dry matter (E-3583). All samples had strong variation in productivity of grain, green matter and hay. Varieties with high rates of productivity elements were selected. It has been established that the majority of the studied varieties belong to middle-grain type according to the 1000-grain mass. Large-grain varieties are Vita (1000-grain mass of 264 g) and Falensky usaty (1000-grain mass of 263 g); small-grain ones are E-411 (140 g) and E-246 (136 g).
