CHROMOSOMAL ABERRATIONS IN A DIPLOID HAWORTHIA SUBFASIATA

Abstract
In 2 diploid specimens of H. subfasciata (2n = 14) several kinds of chromatid and subchromatid aberrations occurred. In some pollen mother cells E-type and U-type bridges were present. In other cells bridges and fragments were formed due to asymmetrical reunion of nonsister chromatids following breakage. A translocation involving the satellites of 2 L pair chromosomes was observed in one plant.
