Abstract: Lycopersicon peruvianum Mill. and L. chilense Dun., two species of 'Peruvianum complex' were compared for production and characterisation of tomato somatic hybrids. The double selection system "employing kanamycin resistance from tomato (L esculentum Mill.) cuItivar, Pusa Ruby and protoplast regeneration pathway from wild tomato parents" was used for identification of heterokaryons. Somatic hybrid plants were characterised by morphological markers, cytogenetic studies and biochemical analyses. The molecular confirmation of tomato somatic hybrids was obtained by peR-based DNA markers. The importance of selectable marker (nptII) gene from cultivated species during characterisation of somatic hybrid plants was demonstrated.
