%X intra and interspecific variability was measured in the genus lycopersicon for the traits: productivity rate (pr, total number of regenerated shoots/total number of cultures), regeneration percentage (%r, number of cultures regenerating shoots or primordia/total number of cultures) and callus percentage (%c, number of cultures only producing callus/total number of cultures). leaf explants from various genotypes of l. esculentum, l. esculentum var. cerasiforme, l. pimpinellifolium and l. peruvianum were placed on murashige and skoog (physiol. plant. 15: 473-493, 1962) medium + 0.175 mg/l iaa + 2.25 mg/l ba. significant differences among species and among genotypes within the same species were found, while genotypes from different species showed similar responses.
