Abstract
A comparative study was conducted to vindicate micropropagtion and callus culture in Mailing 9 apple rootstock. Supplemented Murashige and Skoog basal salts were used as culture medium. Callus from nodal segments was readily initiated in 1.0 mg I' IBA and 0.5 mg I' BA, on subculturing in 2.0 mg I' NAA embryoids and then shoots were developed. Direct shoot formation from nodal segments was obseved in 1.0 mg I' BA and the most acceptable shoot proliferation was in 1.0 mg I' BA plus 1.0 mg I' NAA. Rhizogenesis in the shoots obtained from path methods was noted superior in 2.0 I"l,lg1-1 lBAwhen exposed for short duration. Survival was 100 percent in sand or silt. Both the methods were found very effective and equally poised.
