*(seedlings inoculated in flats and only resistant individuals transplanted to field, to prevent spreading the rust to other cultures).
Singleton reported 35% recombination between D7-G1 and 27% between D7-R. This suggests the order is G1-R-D7, but might be different. However, if D7 falls to the left of R it should show fairly strong linkage with Rp, but it does not. Therefore the order in chrom. 10 is:
