Chromosome variation inCrocus. I

  • Published:
Journal of Genetics Aims and scope Submit manuscript

Summary

The somatic chromosome complements of sixty-four species and varieties ofCrocus were examined, and a comparison of them shows that the chromosomal variation in the genus results from:

  1. (i)

    Hybridisation and polyploidy.

  2. (ii)

    Fragmentation and possibly fusion.

  3. (iii)

    Genotypic change controlling bulk and width of the chromosomes.

The occurrence of certain species with an odd somatic number of chromosomes shows that clouai propagation must have been comparatively extensive.

Finally a comparison betweenCrocus andCrepis is made and certain similarities and differences noted.
