摘要：

The segregation of isozymic loci for leaf peroxidases (L2Per) has been investigated in backcrosses and F2 offspring of rye lines having purple seeds (Ps) and monstrosum ears (mo). The Ps, L2Per-3b, mo, and L2Per-2 loci were linked. The Ps and mo loci have been previously located on the 2R chromosome, and the L2Per-3b and L2Per-2 loci have been located on the 2RS chromosome arm. The results favor the gene order Ps...L2Per-3b...mo...L2Per-2 or Ps...mo... L2Per-3b...L2Per-2. The position of the loci relative to the centromere is still not known, but the obtained results suggest that the mo locus could be located on the 2RS chromosome arm. On the basis of previously reported linkage groups, the most probable arrangement of the loci located on chromosome 2R is: dw2...Ps... (L2Per-3a...L2Per-3b...mo)...L2Per-2. It has not been possible to known the position of L2Per-4 loci (also located on 2RS chromosome arm) relative to L2Per-3a and L2Per-3b loci.
