Viability and fertility studies using cryopreserved coconut pollen Pollen of both WCT and COD cultivars retained its viability and fertility even after a storage period of 4 years in liquid nitrogen.
Released twelve improved varieties of coconut (Chandra Kalpa, Kera Chandra, Chowghat Orange Dwarf, Kalpa Pratibha, Kalpa Dhenu, Kalpa Mitra, Kalparaksha, Kalpasree, Kalpatharu, Kalpa Jyothi, Kalpa Surya and Kalpa Haritha)
Released five high yielding hybrids of coconut - Chandra Sankara, Kera Sankara, Chandra Laksha, Kalpa Samrudhi and Kalpa Sankara.
Released six high yielding varieties (Mangala, Sumangala, Sreemangala, Mohitnagar, Swarnamangala and Kahikuchi) and two hybrids of arecanut (VTLAH1 and VTLAH2)
DNA finger printing using microsatellite markers have been carried out in 139 coconut accessions to document the genetic integrity and diversity. A panel of SSR markers have been identified for confirming the hybridity of D x T hybrids (CGD x WCT) which will ensure supply of genuine hybrids to farmers.
Protocol for regeneration of coconut plantlets from plumule explants through somatic embryogenesis developed.
Cryopreservation techniques have been standardized for mature coconut zygotic embryos and coconut pollen.
Tissue culture protocol has been standardised for mass multiplication of arecanut from inflorescence explants and genetic fidelity of in vitro derived plantlets has been assesed using molecular markers
RAPD markers have been identified for differentiating tall and dwarf cultivars of coconut. These markers have been converted as SCAR markers and validated.
