- Observation Chromosome numbers were first reported for S. tripartitum, S. tenuispinum and S. vaillantii.
- Observation The first genus-level karyotype analysis of L. rantonnei is reported.
- Observation Karyotypes were generally symmetrical, with chromosomes under 4 μm.
- Observation Metacentric chromosomes comprised 69%.
- Observation Submetacentric chromosomes comprised 24%.
- Observation Subtelocentric chromosomes comprised 7%.
- Observation S. tucumanense, S. palinacanthum and Solanum sp. Acanthophora mainly had sm and st chromosomes.
- Observation All species had nucleolar organizing regions and attached satellites on one chromosome pair.
- Observation All species were cytologically distinguishable.
- Observation Karyotype data did not separate L. rantonnei from Solanum species.
- Observation Karyotype results supported S. tucumanense as distinct from S. pseudocapsicum.
