Abstract:
1. A lettuce plant comprising an allele conferring resistance to Bremia lactucae , wherein the plant lacks a second allele genetically linked to the allele conferring resistance in Lactuca saligna , wherein the second allele confers a trait selected from the group consisting of adventitious shoots, reduced plant diameter and bubbled leaves, wherein the allele conferring resistance to Bremia lactucae is selected from the group consisting of (a) a RBQ5 allele of Lactuca saligna conferring quantitative resistance to Bremia lactucae , wherein the plant lacks an allele genetically linked to the RBQ5 allele in Lactuca saligna conferring adventitious shoots, and (b) a RBQ6 allele of Lactuca saligna conferring quantitative resistance to Bremia lactucae , wherein the plant lacks an allele genetically linked to the RBQ6 allele in Lactuca saligna conferring reduced plant diameter or bubbled leaves.
