✦ Synopsis

Beta vulgaris, sugar beet, haploid, C-banding, idiogram, chromosome identification SUMMARY Some haploids isolated among the progeny from crosses involving several genotypically different motherplants of Beta vulgar-is L., were used for an investigation on chromosome morphology of the genus Beta.

The length of both the long and short arms proved to vary considerably for each chromosome, so that a representative idiogram of the 9 chromosomes could not be made. Staining the chromosomes according to the BSG-technique revealed only bands in the centromere regions. However. one chromosome with a narrow band in the short arm could be identified, which was supposed to be the nucleolar chromosome. The C-bands presumably correlate with the heterochromatic blocks as observed in mitotic and meiotic (pachytene) prophase.
