Abstract
Leaf explants of 24 cultivars and 2 F1 hybrids of the common tomato (Lycopersicon esculentum Mill.) and ofL. pimpinellifolium Brezh. were cultured on Murashige-Skoog medium containing different concentrations of NaCl. The cultures of 11 genotypes formed flower buds when cultured on medium containing 0.5% NaCl. Flower formation occurred either by direct differentiation from the leaf cultures or by transition of the apices of regenerated shoots from the vegetative state to floral buds. No flower formation occurred on medium without NaCl or media with 1.0% NaCl or more. There existed great differences in the capacity of in-vitro flower formation in the tomato leaf explants among the genotypes tested. The genotypes whose explants did form flowers were all of determinate growth habit.Keywords
