| Abstract: | A modified Giesma staining technique was used to identify the somatic chromosomes of diploid potatoes. Distinct banding patterns were observed on all 12 chromosomes. Individual chromosomes were identified according to the number and distribution of bands. No significant difference in banding patterns was observed between the chromosomes of Phureja-haploid Tuberosum hybrids and those ofS. chacocnse. The extra chromosome of a trisomic of 5.chacoense was identified as an isochromosome for the long arm of chromosome G. |
