In vitro shoot regeneration from preconditioned explants of chickpea (Cicer arietinum L. ) cv. Gokce

The present study reports the successful shoot regeneration of preconditioned mature embryo and embryonic axis explants of chickpea cv. Gokce . Explants were preconditioned with 10 mgl benzylaminopurine (BA) for 7 days followed by culture on Murashige and Skoog (MS) medium containing 0.25, 0.50, 1.00 and 2.00 mg/l BA with or without 0.25 mg/l naphthalene acetic acid (NAA) supplemented with 4 mg/l activated charcoal and 1 mg/l polyvinylpyrrolidon (PVP). Shoot regeneration was recorded on all explants. Maximum number of (14.75) shoots per explants on mature embryo were recorded on MS medium containing 2.0 mg/l BA with 0.25 mg/l NAA. Whereas, 16.83 shoots per explants were recorded on MS medium containing 2.0 mg/l BA. Presence of NAA in the culture medium decreased the mean shoot length of both explants compared to medium devoid of 0.25 mg/l NAA. Regenerated shoots were rooted on MS medium containing 1.0 mg/l indole-butyric acid (IBA) after 4 weeks of culture. Rooted plantlets were transferred to pots for acclimatization under green house conditions. Key words : In vitro, chickpea, pulse treatment, shoot regeneration.
