The Onobrychis viciafolia is one of the forage and rang land plants that is adapted and spread to different climates of Iran. One of the important disease of this plant is powder mildew in the Lorestan province which damages second and next cutting stages of this plant. To study the correlation between disease severity and forage quality, seeds of 34 populations were planted in field of Khorram Abad city with Ranomize block design by three replications on years of 2008-2011. Evaluation made against powdery mildew disease by four cuttings for three years but it was 2 years for forage quality. There was significant positive correlation between disease severity of infected plants with powdery mildew and percent of total protein (P<0.05). Population of Kermansah with maximum forage yield were higher than any other populations which was rather tolerance to powder mildew. Polycross and Oshnavieh populations with low disease severity index were tolerant. The disease was caused to decrease of forage yield and forage quality of the sainfion populations.
