Aminopeptidase B1: a centromere marker for chromosome 6B of wheat
1992
Sacco, F. | Tranquilli, G. | Gorgoschidse, L. | Suarez, E.
Recombination values between the centromere, Amp-B1, and Lr3 were evaluated using a 'Chinese Spring' double-ditelosomic line for chromosome 6B and the euploid variety 'Sinvalocho M.A.'. Recombination was not observed between the centromere and Amp-B1, but between the centromere and Lr3 the value was 52.8 +/- 3.74%. A particular progeny during two successive backcross generations showed abnormal behaviour that resulted in a reduced number of recombinants between the centromere and Lr3, probably a consequence of the karyotypic instability of 'Sinvalocho M.A.'.
