Summary
The chromosomal locations of two enzymecoding genes were investigated using allele dosage effects in two Allium cepa alien addition lines possessing different A. fistulosum chromosomes as the trisomes. Adh-1 has been assigned to the A. fistulosum sub-telocentric chromosome 5, while Pgm-1 is on the A. fistulosum submetacentric chromosome 4. Karyotype data of a shortday cultivar of A. cepa, ‘Temprana’, A. fistulosum ‘Ishikura Long White’, and the relevant chromosomes of the two trisomies are presented.
