Anthers of five rice varieties viz. BR-5, BR-31, BR-34, BR-37 and BR-38 were cultured for callus induction and plant regeneration. Anthers were cultured on N6, Z2 and R2 media containing the same hormonal combination 2.5 mg/l NAA, 0.5 mg/l Kn and 0.5 mg/l 2.4-D and incubated at 25 plus minus 1 degree centigrade in dark for callus induction. All the varieties in Z2 medium, two varieties in N6 medium and only one variety in R2 medium produced callus. Out of all responding varieties BR-38 produced highest percentage of callus. Calli induced in different induction media were transferred to MS medium supplemented with 2.0 mg/l BAP + 0.5 mg/l Kn + 1.0 mg/l NAA and 1.0 mg/l Kn + 1.0 mg/l NAA and incubated at 25 plus minus 1 degree centigrade in light for plantlet regeneration. Green plantlets appeared within 15-30 days of culture and highest number of regenerated green (33.32%) and albino (11.27%) plantlets were produced in BR-37.
