Fig. 2. Genetic maps of marker loci on rice chromosomes 2, 11, and 12, respectively, near the (A) Pi-b gene from Te-Qing using combined data of crosses segregating for resistance to rice blast race IE-1K and presence of the Pibdom gene marker; (B) Pi-k locus conferring resistance to rice blast races IB-45, IB-54, or IG-1 using combined data of Pi-kh and Pi-ks allele segregation; and (C) Pi-ta2 gene from Katy or Kaybonnet using combined data of crosses segregating for resistance to rice blast race IB-49. Genetic distances in Morgan map units of recombination are displayed on left of each chromosome, with the centromere of chromosome 12 shown at its expected position.
