Abstract

Lactuca saligna L., Lactuca serriola L., and Lactuca virosa L., which are cross-fertile with cultivated lettuce (L. sativa L.) were tested for resistance to lettuce infectious yellows virus in greenhouse and field tests. Fifteen of 25 L. saligna accessions were resistant, whereas 50 accessions of L. serriola and seven accessions of L. virosa were susceptible.
