Abstract
Callus and plant regenertion were induced from shoot portions of mature embryos (dry seeds) of five high tannin Sorghum bicolor (L.) Moench cultivars. The explants were cultured on Murashige and Skoog medium with altered concentrations of 5 salts, supplemented with 150 mg/L L-asparagine, 5mg/L 2,4-Dichlorophenoxyacetic acid and 0.05mg/L kinetin. Calli which were yellow and globular were formed with 70–90% frequencies. The subculture medium which gave best results was MS with 2mg/L 2,4-Dichlorophenoxyacetic acid and 0.5mg/L kinetin. Plants were regenerated on MS medium supplemented with 150mg/L L-asparagine and 0.2mg/L kinetin with regeneration frequencies of 11–48%.
