Moench] Sairam, R V Seetharama, N Devi, P S Verma, A Murthy, U R Sorghum A protocol for plant regeneration from mesophyll/protoplasts of sorghum [Sorghum bicolor (L.) Moench] was developed. The yield of intact protoplasts, their subsequent divisions and regeneration were genotype-dependent. The genotype 296B was always more responsive than IS 32266. For 296B, the sixth leaf from 18-day-old plants kept in dark for 2 days before harvesting was found to be the most suitable source of viable protoplasts. The first division was observed 10–12 days after plating, and the second division after 12–14 days. The maximum plating efficiency was 4.8% in 296 B, followed by 2.48% in IS 32266. Microcolonies were visible after 25–30 days, and microcalli after 60–75 days. Whole plants were obtained after 6–8 weeks of culture of microcalli on MS medium containing 0.2 mg l–1 kinetin and 2 mg l–1 BAP. The frequency of regeneration in 296B and IS 32266 was 12.80% and 10.58%, respectively. Ten plants transferred to pots in the glasshouse established well. The seeds collected from glasshouse-grown plants were sown in the field where plants were grown to maturity.
