Chromosome pairing set and the presence of unreduced gametes explain the possible origin of polyploid progenies from the diploids 'Tosa-Buntan' x 'Suisho-Buntan' pummelo [Japanese]

摘要

To clarify why polyploids were generated from the cross of the diploids 'Tosa-Buntan' and 'Suisho -Buntan' pummelo (Citrus grandis [L.]Osb.), the chromosome compositions of their di-, tri-, and tetraploid progenies, based on CMA staining, and their chromosome parings were observed.
