In a cross between the two resistant accessions Col-0 and Ler-0, a 15:1 segregation was found in F2, suggesting the presence of unlinked resistance loci to Leptosphaeria maculans. One hundred Col-4 x Ler-0, and 50 Ler-2 x Cvi-1 recombinant inbred lines, and seven susceptible Ler-0 x Ws-0 F2 progenies were examined to identify the two loci. Resistance in Col-4, Ws-0 and Cvi-1 (RLM1) was mapped to the marker m305 on chromosome 1. Col-4 x Ler-0 and Ler-2 x Cvi-1 mapping populations located RLM2… CONTINUE READING
