Abstract
Chromosome constitution was analyzed in progenies from the translocation heterozygous allotetraploids (2n=34, AATBBT) of Scilla scilloides Druce. Fifteen plants out of 139 selfed and 25 open-pollinated progenies were homo- or heterozygous for the chromosome a2S carrying a large satellite, though the parental plants had no satellited a2. This SAT-chromosome is similar to satellited a2 present in the Korean diploid AA but not to non-satellited a2 found in allopolyploids. Thus satellited a2 which incurred differential amphiplasty may possibly have recovered its normal shape in the allotetraploids. Diploid AA comprising satellited a2 may possibly contribute to the synthesis of allopolyploids.
