Objective The Potato Leaf Roll Virus (PLRV) is one of the most devastating virus causing severe yield loss worldwide in potato. The comprehensive observations were made to study the PLRV infestation in major potato growing areas of Bihar (India) and further detailed molecular basis of PLRV aggravation was established. Results Although population of aphids were found comparatively lower with maximum symptomatic plants, our molecular data further confirms the presence of PLRV in all possible
