Abstract

Sesbania aculeata is a multipurpose legume crop grown primarily for green manuring in the rice-based cropping system. Besides this, it is an industrial crop and is also used as food in many parts of the world. The present work reports for optimization of various parameters (growth medium, plant growth regulators, pre-conditioning, orientation of explant, and presence of thiol compounds) affecting in vitro regeneration using mature cotyledon explants. The 5-day-old mature cotyledon explants excised from seedlings grown on Murashige and Skoog (MS) salts and Gamborg (B5) vitamins medium containing 15 μM 6-benzylaminopurine were cultured with its adaxial side facing on medium containing 2.5 μM 6-benzylaminopurine and 50 mg/L thiourea and produced multiple shoots (7 ‒ 8) in 100% cultures within 28 days. Healthy shoots were rooted on half-strength Murashige and Skoog (MS) salts and full-strength vitamins medium augmented with 2.5 μM indole-3-butyric acid.
