The paper outlines the results of experiments with the lupine yellow of Progressive cultivar. It was established that its infection with bean yellow mosaic virus reduces the indices of plants growth and development (decrease of plant mass on 14,0-30,4 %, root mass – on 8-24 % in different phases of ontogenesis, area of leave surface – on 10 %). The viral infection prevents the realization of the photosynthesis and symbiotic nitrogen fixation potentials (the reduction of chlorophyll a contents in leaf on 5,2 %, chlorophyll b – on 6,5 %, nodule masses – on 13-32 %, nitrogenase activity – on 9,1 %). That reduces green mass (on 15 %) and grain productivity (the amount formed bob in phase of the blossom was decreased on 27,5 %).
