Key words: BAP-Benzyl Amino Purine, AS-Adenine Sulphate, TDZ-Thidiazuron, Zn-Zeatin, RM-Regeneration Media, IAA- Indole-3-Acetic Acid and MS- Murashige and Skoog.

Abstract

In the present investigation, three tomato cultivars Pusa Ruby, Vaibhav and Arkamegali (Solanum lycopersicum L.) were selected for multiple shoot induction. The explants cotyledon, hypocotyl and epicotyl of all the cultivars of tomato were cultured on MS medium fortified with different concentrations of BAP (1.0 to 4.0 mg/l), TDZ (1.0 to 4.0 mg/l), Zeatin (0.5 to 1.0 mg/l), AS (5.0 to 20 mg/l) and 0.1 mg/l IAA .
