Karyomorphological studies of the somatic chromosomes in five species of Lycopersicon adopting an improved squash technique have been reported. No significant differences of evolutionary importance could be detected among the karyotypes of species studied, suggesting that micro- and macro-mutations have been more important in the diversification of these Lycopersicon spp. An interesting-chromosomal biotype for the satellite chromosome has been reported in L. pimpinellifolium.
