摘要：This study was conducted to determine the optimum concentrations of 2, 4-D, L-proline and casein hydrolysate (CH) for efficient callus induction and plantlet regeneration from culturing mature embryos of Sangyod, an economically important indica rice variety in Thailand. The highest frequency of callus induction (73.08 ± 2.65 %) was obtained from MS medium supplemented with 2 mg/L 2,4-D, 750 mg/L CH and 200 mg/L L-proline. The combination of 1 mg/L BA, 0.5 mg/L Kn and 0.5 mg/L NAA containing solidified MS medium gave the maximum mean fresh weight of callus (938.9 ± 44 mg), green spot formation (64.17 ± 7.08 %), shoot induction frequency (66.25 ± 6.80 %) and mean number of shoots/explant (6.12 ± 0.36 shoots). The greatest mean number of shoots/explant (14.93 ± 0.97 shoots) and root formation percentage (82.71 ± 3.03 %) was observed in liquified MS medium supplemented with 0.5 mg/L NAA and 1 mg/L BA.
