Legumes are important components of the human diet due to their high and valuable protein content. A large part of harvest is used as regionally produced protein-rich animal feed. White lupine meets soybean yield and protein quality and its cultivation is of high ecological value due to air nitrogen fixation by bacterial symbiosis. As a preceding crop lupines hand the fixed nitrogen over to the following; a step to avoid excessive nitrate in soil and groundwater due to artificial fertilization. Lupines increase biodiversity in the agricultural landscape and are food source for insects during its flowering period. Appearance of anthracnose disease, caused by the pathogen Colletotrichum lupini, led to a fast reduction in White lupine cultivation. The pathogen attacks lupine plants at different developmental stages and developing resistant cultivars is the most economical method and of vital significance for White lupine cultivation. The LUPISMART project aims to 1) identify anthracnose tolerant lines in genetic resources, 2) develop molecular markers for marker assisted selection to improve ecological and conventional breeding programs and 3) provide PreBreeding material which may lead to a recovery of White lupine cultivation in Germany. A genepool of White lupine is tested for its tolerance against anthracnose in the field and in the lab. The same genepool is genotyped by a GBS approach resulting in thousands of genome wide SNPs. An association study detects all genomic regions significantly correlated with anthracnose tolerance and further economically important traits. SNPs significantly associated with breeding relevant traits are transferred to a genotyping platform that can be applied for selecting quality improved and anthracnose tolerant breeding lines. Providing anthracnose tolerant PreBreeding material and tools for efficient marker assisted breeding programs the LUPISMART project will achieve a renaissance in the cultivation of regional White lupine.
