The Giemsa C‐banding technique was found to be a useful tool in the karyotype analysis of Hippophaë. Three strains of H. rhamnoides L. were studied, two representing ssp. rhamnoides , one ssp. mongolica Rousi. A C‐banded idiogram of one of the ssp. rhamnoides strains is presented. The C‐bands are generally located on both sides of the centromere, but their sizes and numbers vary between chromosomes. Certain small differences in the banding pattern could be seen between the strains. The C‐banded karyotype shows clearly that 2n=24 cannot be an autopolyploid number as has been repeatedly assumed. In all probability, it represents the diploid level.
