of TB tests of unplaced mutants
--Stinard, PS, and Jackson, JD
The past two years, we have reported the
results of TB mapping crosses made to symbolized unplaced mutants in the
Coop's collection (MNL 72:79 and MNL 73:90). This year, we observed grow-outs
of the TB crosses made last year to mature plant mutants. The mutants for
which we obtained positive results are summarized in Table 1. Additional
crosses with linkage markers will be made to confirm chromosome arm placement,
and allelism tests will be conducted with mutants with similar phenotype
located on the same chromosome arm.
