Abstract
Infraspecific cytogenetical variation was studied in a diverse collection of five non-cultivated and cultivatedCucumis sativus accessions. The individual chromosomes of different accessions could be identified by the C-banding pattern and chromosome measurements. About 40–50% of the genomic area are made up of heterochromatin inC. sativus. The non-cultivated accessions exhibit more heterochromatin and lower chiasma frequencies per pollen mother cell than cultivated accessions. There is infraspecific variation in C-banding pattern, karyomorphology and multinucleolate cells. The use of C-banding in infraspecific classification is discussed.
