Effects of Genotype on Induction of Callus and Plant Regeneration Potential in vitro Anther Culture of Rice (Oryza sativa L.)
The present studies were carried out to evaluate the response of anthers of six rice genotypes to callus induction and plant regeneration. For callus induction Z2 media supplemented with 2, 4-D 0.5
mg l-1, NAA 2.5 mg l-1 and Kinetin 0.5 mg l- was used. Of the six genotypes, five gave good callusing response. Highest callus induction was observed in BRRI Dhan-29 (8.06%) and lowest in BR-10 (1.42%). Callus induction frequency varied from 1.42-8.06% depending on genotypes. Modified MS medium supplemented with Kinetin 0.5 mg l-1, BAP 2 mg l-1 and NAA 1.0 mg
l-1 was used for plant regeneration. The results showed a significant genotypic difference in callus induction and plant regeneration. The regeneration of plantlet from anther derived calli ranged from 57-75% conclusion.
