Abstract

|
|
|
C-banded karyotypes in A. anisopodium, A. sacculifenm, A. deltoide-fistulosum and A. splendens were investigated. The chronosomc compositions were diploid of 2n=16 in A anisopodium and A. splendens, and tetraploid of 2n=32 in A. sacculiferum and A. deltoide-fistulosum. The bands were distributed in telomeric parts of the chromosomes dominantly in addition to interstitial regions sporadically, resulting in the specific C-banded karyo types according to the species. No centromeric band was observed in these species except only one chromosome in A. deltoide-fistulosum. The interspecific relationship based on the C-band distribution will be discussed.
