Impact of positive selection on incidence of different viruses during multiple generations of potato seed tubers in Uganda

This article assesses to what extent positive selection over several seasons can reduce six different virus incidences in seed lots of different starting quality in Southwestern Uganda. The results clearly show that crops planted with seeds from positive selection have a reduced virus incidence compared to those from farmers’ selection when the treatments are applied over multiple (in this case, three) seasons, thereby reducing the level of secondary infection in the next-season crop. »
