Abstract:

To meet the demands of good quality and true to type planting material of Vanda hybrid ‘Dr. Anek’, in vitro micropropagation protocol was developed at Center for Plant Biotechnology and Molecular Biology (CPBMB), College of Horticulture, Kerala Agriculture University. The different explants tested to initiate the cultures were leaf, root, stem and inflorescence segments. The results of the experiment showed that treating the explants with 0.1 per cent carbendazim for 20 minutes, followed by 70 per cent ethanol for 5 minutes and 0.1 per cent mercuric chloride for 5 min effectively reduced the microbial contamination with highest percentage of explant survival. The study showed positive results for inflorescence segments inoculated on to 1/2 MS + 10 mg l-1 BA+ 2 mg l-1 TDZ+30 g l-1 sucrose+7.5 g l-1 agar + 250 mg l-1 cefotaxime as observed as direct shooting of the dormant buds. The established cultures successfully produced multiple shoots on MS+4.5 ml l-1 BA +30 g l-1 sucrose + 7.5 g l-1 agar + 250 mg l-1 cefotaxime both when inoculated with and without the stalk in about 100 days of inoculation of explant. The percentage of rooting was observed to be 72.41 per cent when elongated shoots of about 4 cm obtained from cultures initiated without stalk were transferred to rooting media with a composition of MS + 0.5 mg l-1 NAA + 1 mg l-1 IAA +30 g l-1 sucrose +7.5 g l-1agar + 250 mg l-1 cefotaxime. Hence it can be concluded that the developed micropropagation protocol can be used for commercial production.
