Resistance to anthracnose in narrow-leafed lupin (<em>Lupinus angustifolius</em> L.): sources of resistance and development of molecular markers

Abstract

Breeding lines and genebank accessions were screened for novel anthracnose resistances by use of a reliable and standardized resistance test under greenhouse conditions. While all the German cultivars tested proved to be susceptible, two breeding lines were identified which displayed strong resistance to Colletotrichum lupini. One of these was subsequently tested in the field and strong resistance could be confirmed. F2 populations for the mapping of the potentially novel resistances were started to be set up. For mapping purposes, 150 gene-based molecular markers provided by M. Nelson (University of Western Australia, Perth) are being used. Sequence information from the Medicago truncatula and Lotus japonicus genomes is also addressed to develop additional molecular markers in narrow-leafed lupin.
