Six almost completely resistant (CR) accessions of L. virosa and one partially resistant (PR) accession of this species were intercrossed to investigate the inheritance of resistance and the location of the resistance genes. The CR in all accessions appeared to be governed by one (incompletely) dominant allele designated as Nr and the PR and possibly susceptibility (S) too by a recessive allele nr. The alleles for CR, PR and S were present on one and the same locus. It is still uncertain… CONTINUE READING
