S.  aChromosome stickiness in meiosis of a brazilian Paspalum accession.h[electronic resource]  c2000  aCitogenetic studies carried out over a period of 2 consecutive years on a still unidentified Brazilian accession of Paspalum (BRA-014176) revealed a meiotic mutation causing chromose stickiness in microsporogenis. In all inflorescences collected in both years, meiosis was normal until diakinesis. Chromosome stikiness became evident from metaphase I, whwn the cromosome appeared as a dense cluster. Chromosome bridges of different thickeness were observed from anaphase I to the microspore stage. In the microspores, the necleus became pynotic and in the pollen grain the chromatin suffered degeration causing pollen sterility.  amicrosporogenesis  aPaspalum  aChromosone stickiness  aMutant1 aFREITAS, P.
