Abstract
The present study was conducted to determine the optimum in vitro culture condition for callus induction and plant regeneration from mature seeds of bermudagrass (Cynodon dactylon cv. Common). It was revealed that mature seeds cultured on MS medium supplemented with 2 mg/L 2,4-D, 0.5 g/L proline, 0.5 g/L casamino acid and 3 g/L Gelrite under light condition produced the highest percentage of callus formation (39.2%). The most suitable medium for plant regeneration from dehydrated calli was MS agar medium supplemented with 0.5 mg/L 2,4-D, 2 mg/L BA, 0.5 g/L proline, 0.5 g/L casamino acid 3 g/L Gelrite which induced the highest percentage of calli forming shoots (57.7%). The frequency of callus induction and plant regeneration were the highest on sucrose, followed by maltose. The shoots were rooted at the highest rate (100%) when transferred onto 1/2 MS medium. Regenerated plants were morphologically uniform with normal growth pattern. (Key words : Bermudagrass, Callus, Plant regeneration, Tissue culture)
