In an attempt to optimize the in vitro-regeneration conditions necessary for the genetic manipulation of tomato species, we examined several hybrid lines and wild species (peruvianum, pimpinellifolium, glandulosum) of Lycopersicon for. their, different regeneration ability. The basal medium used for callus growth and organogenesis was MSB (MS + B5) supplemented with three combinations of TDZ (Thidiazuron) 0.5mg/L+NAA 0.5mg/L, BA 2.0mg/L+NAA0.05 mg/L, and zeatin 3.0 mg/L + IAA 0.02 mg/L. In the genotype of Lycopenicon grandulosum, combination of TDZ and NAA was more effective in inducing shoot and root differentiation than those of BA and NAA or zeatin and IAA. When all genotypes tested were considered, however combination of zeatin and IAA was shown to be the best in shoot regeneration. Result indicate that callus and organogenesis of Lycopenicon species are dependent upon the hormone types and plant genotypes, but MSB medium with zeatin 3.0 mg/L + IAA 0.02 mg/L maybe appropriate for genotype-independent plant regeneration system of Lycopercicon species. We also tried TDZ as a cytokinin source in tomato tissue culture and found it highly significant in tomato regeneration system.
