Abstract
The complex structure of the rp1 rust resistance locus of maize allows two or more resistance genes to be recombined together in coupling phase. The phenotypic effects of the Rp1-DJ compound gene, which carries both Rp1-D and Rp1-J, were analyzed. The Rp1-DJ compoundgene was associated with a chlorotic spotting phenotype in some genetic backgrounds. At the seedling stage, lines carrying Rp1-DJ are fully susceptible to Puccinia sorghi biotype HI1, which is virulent on lines with the two genes singly. At laterstages of growth, however, Rp1-DJ lines show partial resistance when compared with sibling lines not carrying the compound gene. The Rp1-DJ gene also confers partial resistance to P. polysora in adult plants.
