Samenvatting
Uit combinaties van A1- en A2-paringstypen vanPhytophthora infestans werden zowel bij tomaat als bij aardappel oösporen verkregen in de plant. Oösporen werden niet in de bladeren gevormd, maar werden veelvuldig aangetroffen in de epidermis van de stengels. De proeven werden uitgevoerd in de klimaatkamer; de veldsituatie moet nog onderzocht worden.
