The effect of potato spindle tuber virus on growth and yield of Saco potatoes

  • James E. Hunter
  • Avery E. Rich


The presence of spindle tuber virus in Saco potatoes caused slow development of sprouts and slow emergence of plants. Infected plants were stunted and spindly with a sharp angle of branching, and the leaves developed tip burn. Infected plants died prematurely and the number and size of tubers were smaller than expected. Infected hills yielded only 35.2% as much as healthy hills. Yield reduction was due partly to fewer tubers per hill but mostly to their smaller size. This factor, plus the spindle shape, would place many of them in an inferior grade
