Karyotype analysis in wild species of Solanum spp


, : Karyotype analysis in wild species of Solanum spp. Capsicum Newsletter (Special issue): 272-277

Root tips of S. sisymbriifolium and S. torvum, wild relatives of S. melongena, were stained in Feulgen stain and analysed using image processing. The chromosome number in all cases was 2n = 2x = 24. S. sisymbriifolium has 12 pairs of metacentric chromosomes, with a satellite attached to the short arm of the longest chromosome. Chromosome length ranged from 1.65 to 2.63 micro m. S. torvum has 2 (VI and XI) submetacentric and 10 metacentric chromosomes.
