Summary
As well known in Chinese Spring wheat all the possible
telocentric chromosomes except 7DS (isolated in cv. Canthatch by Dr.
Kerber) have been isolated and are ready to use for cytogenetical
study. In addition, 14 lines of doubleditelosomic and reasonable
number of lines of ditelomonotelosomic are now available in
tetraploid wheat (Joppa 1987, Nishikawa unpublished). By use of these
aneuploids monotelodisomic analysis and doubletelotrisomic analysis
can be easily and efficiently made, which provide the following
informations;
(1) Gene-chromosome arm association, (2) recombination value between
marker and centromere, (3) gene order, and (4) centromere
position.
