Resistance to Nasonovia ribisnigri biotype 1 (Nr:1) from Lactuca serriola

摘要

The present invention relates to a lettuce plant (Lactuca sativa L.) resistant against Nasonovia ribisingi biotype 1 (Nr : 1 ) representative seeds of which were deposited under NCIMB accession number 41763. Such lettuce plant is obtainable by crossing a lettuce plant with a plant grown from seeds of seedlot 10G.913569 representative seeds of which were deposited with the NCIMB under NCIMB accession number 41763 and selecting preferably in the F2 progeny of the cross for plants being resistant against Nasonovia ribisingi biotype 1 (Nr:1).
