A study of meiosis in the PMC's of five populations of C. diffusa (2n=2x=30) belonging to three sub-species, diffusa diffusa, diffusa aquatica and diffusa montana, revealed varying degrees of chromosomal associations suggesting the presence of interchange complexes in these populations. Fertility estimates showed a high proportion of infertile microspores and concomitant reduction in seed set. These could be traced, at least in part, to the presence of interchange heterozygotes in these populations.
