AbstractCytological identification of primary trisomics is an important part in the cytogenetic study of a species. The objective of this study was the Cytological identification of nine primary trisomic types in sugarbeet (Beta vulgaris L.). Karyotype analyses were conducted in somatic metaphase and late-prophase cells. All nine types of primary trisomics in sugarbeet were cytologically identified by means of somatic karyotype analysis. Not all extra chromosomes could be identified with certainty at metaphase because of their similarity in size and arm ratio. Somatic prophase analysis was found to be useful in confirming the results of metaphase analysis of the extra chromosome present in some trisomic types.
