Pollen plants were obtained from anther-derived calli of the indica rice variety Basmati-370. Anther-response (anthers producing pollen derived calli) and plant regeneration frequency from the pollen derived calli. was very low. Donor plants which flowered at the average max/min. temperature of 34.2°/23.3°C gave a significantly higher anther-response to in vitro techniques, than did those which flowered at 29.1°/16.4°C. Somatic callus induction and subsequent plant regeneration was readily obtained from mature seed embryos. While 2,4-D or 2,4,5-T (1 or 2 mg/l) proved highly efficient for callus induction, tryptophan (50 or 100 mg/l) induced a high frequency of green plants from the calli.
