In this study, five lowland NERICA lines, namely, NERICA-L 8, 38, 42, 47 and 49, were evaluated for resistance to rice yellow mottle virus (RYMV) as well as for the impact of the disease on reproductive and yield losses. Parameters such as plant height (cm) at maturity, percent productive tillers plant-1 , number of panicles plant-1 , number of grains panicle-1 , 1000-grain weight plant-1 , and percent spikelet fertility plant-1 were measured. And yield loss was calculated based on mean… CONTINUE READING
