Abstract

The karyomorphological analysis of Solanum viarum Dunal showed the somatic chromosome count to be 2n=24 with n=12 normal bivalents which corroborates previous report. The chromosomes are small with an average size 2.54 ±0.18μm having karyotype formula 2A+4B+12C+6D. The karyotype is symmetric in nature and falls under “1A” of Stebbins symmetric index. The somatic chromosome count and constancy of the karyotype recorded in the present population could be utilised in exploiting cytological and karyomorphological variability among the ecotypic populations of the species.
