R gene homologue loci were correlated to described R loci by comparison with flanking RFLP or morphological markers. Superscript numbers give references for each resistance trait.

r4 probe identifies a rice yeast artificial chromosome clone containing Xa-1; see text.

Cosegregation was found in 71 double haploid progeny segregating for Mla-6.

Hv-b9 maps in the same genetic interval as Rpg1.
