Abstract: The callus embryoid plant regeneration was developed using immature seeds of <i>Aerides maculosa</i> Lindl. and <i>Rhynchostylis retusa</i> (L.) Bl. Immature capsules of 5-10 wk after pollination (<i style="mso-bidi-font-style:normal">A. maculosa</i>) and<i style="mso-bidi-font-style: normal"> </i>10-20 wk after pollination (<i style="mso-bidi-font-style:normal">R. retusa</i>)<i style="mso-bidi-font-style:normal"> </i>were used for callus induction. In both the species, best response of callus induction was observed on Vacin and Went (VW) medium supplemented with 15% coconut water (CW, v/v). In <i style="mso-bidi-font-style:normal">A. maculosa</i>,<i style="mso-bidi-font-style: normal"> </i>maximum number of protocorm-like bodies (PLBs; 13.93 per callus) was noted on VW medium supplemented with BA (1 mg L<sup>-1</sup>)+NAA (1 mg L<sup>-1</sup>) + 15% CW. While in <i style="mso-bidi-font-style:normal">R. retusa</i>, maximum number of PLBs (15.83 per callus) was noted in Murashige and skoog (MS) medium supplemented with BA (1 mg L<sup>-1</sup>)+NAA (1 mg L<sup>-1</sup>)+15% CW. <i style="mso-bidi-font-style:normal">In vitro</i> regenerated plantlets of both the species were acclimatized to green house conditions. The highest survival rate of plantlets (60%) was noted in the combination of charcoal pieces, brick pieces (1:1) and coconut husk.
