- W2268822015 abstract "The amphidiploid rose 86-7 ( Rosa wichuraiana × R. rugosa rubra ) and its hybrids with the tetraploid breeding selection 82-1134 were analyzed for meiotic configuration frequencies and meiotic abnormalities. Genomic relationships in these hybrids were interpreted with the aid of a model of meiotic chromosome association in tetraploids. The optimized solutions to this model indicated a pattern intermediate between the “211” pattern, with one pair of closest genomes, and the “ring4” pattern, in which one of three possible pairing arrangements is strongly suppressed. The same configuration frequencies could also reflect a “4:0” pattern of equally similar genomes with more than two independent pairing and chiasma-forming domains per chromosome. The observed meiotic abnormalities included chromosome stickiness and asynchronous chromosome contraction within cells. Pollen stainability varied independently of meiotic irregularity or multivalent frequency." @default.
