New evidence for the location of a multiovary or pistilloid gene, mo
(monofactorial recessive), on chromosome 1 was presented by Tazhin (1980).
Four such mutational events (designated mol-mo4) have been
reported previously with no chromosome location evidence presented (Kamra,
1966). Tazhin's report (1980) indicated tight linkage of a 5th mo
isolate with the hulless character (n) located on 1L. No recombination
values for n vs. mo were presented. No allele testing with
this new mo isolate was apparently performed with the four previously
Ramage and Flora (1981) located a possible new genetic male sterile
recessive gene (msg,,ee) on chromosome 1, probably near the centromere.
A complete allele test was not performed with the new mutant to allow
a numerical designation to be given.
These new data do not alter the linkage map of chromosome 1 previously
published in BGN 11.
As the newly appointed coordinator of chromosome 1, I put out a standing
request to any and all barley workers for copies of any of their publications
that deal with genes located on chromosome 1, including BGN papers as they
are submitted to the editors. I would appreciate this help immensely.
