ABSTRACT: In plant tissue culture system, the excessive supply of plant growth hormones may inhibit further growth and development of the regenerants and sometimes it may induce somaclonal variation. In this study, the optimum concentration of plant growth hormones for in vitro regeneration of Oryza sativa L. cv. MRQ 74 was identified and subsequently the occurrence of somaclonal variation of regenerated plantlets was determined through cytological analysis of in vivo and in vitro grown plantlets. MS media supplemented with 0.1 mg L-1 BAP in combination with 0.1 mg L-1 NAA was found to be the optimum concentration for shoots and roots induction of Oryza sativa L. cv. MRQ 74. Plantlets derived from MS media supplemented with 0.5 mg L-1 2,4-D showed higher...
