ABSTRACT

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 2.5mg/l NAA, 0.5mg/l Kn and 0.5mg/l 2.4-D and incubated at 25 ± 1oC in dark for callus induction. All the varieties in Z2 medium, two varieties in N6 medium and only one variety in R 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 ± 1oC 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.
