The seeds of both cultivars were sterilized by sodium hypochorite (clorox) 15% for 10 minute. Then, embryos were transferred to MS medium supplemented with 2, 4D at four different concentration of 0, 0.5, 1.0 and 2.0 mg/l for 8 weeks. The result revealed that MS medium supplemented with 0.5 mg/l 2,4-D could provide 100% of callus induction of Sew&nbsp; Deng rice &nbsp;and Nor Prae rice with 0.0414 and 0.0652 g dry weight, respectively.&nbsp;</p> ER -
