Item Detection of sequence characterized amplified region (SCAR) markers linked to sex expression in Carica papaya L(National Science Foundation:Colombo, 2008-6) Niroshini, E.; Everard, J.M.D.T.; Karunanayake, E.H.; Tirimanne, T.L.S.Item Development of Genomic and EST Microsatellite Markers and Their Usefulness in Genetic Conservation and Improvement of Tea (Camellia sinensis L.)(Tea Research Institute:Talawakelle, 2012) Mewan, K.M.; Abeysinghe, I.S.B.; Saha, M.C.; Yongzhen-Pang; Karunanayake, E.H.; Tirimanne, T.L.S.; Everard, J.M.D.T.; Dixon, R.A.Item Inheritance of RAPD markers in the coconut palm Cocos nucifera L.(Postgraduate Institute of Agriculture, University of Peradeniya:Peradeniya, 1996) Everard, J.M.D.T.; Katz, M.; Gregg, K.Item Is there ecological adaptation in coconut nursery seedlings stage?:a preliminary investigation(Coconut Research Institute of Sri Lanka. Lunuwila, 1994-95) Peries, R.R.A.; Everard, J.M.D.T.Seedlings were raised in three nurseries representing different agro-ecological regions, to test whether growing seddlings exhibited adaptation to a particular environment. Seed nuts were also selected from agro-ecologically different regions. The T x T seed nuts from the isolated coconut seed garden showed a faster rate of germination at all sites compared to Moorock seed nuts (from the North western region) or Dehigahalande seed nuts (from the Southern region). The vigor of seedlings (a qualitative assessment based on the number of vigorous seedlings selected) was enhanced by a good soil water supply during the early nursery stages combined with a higher level of solar-radiation at the nursery site. There was no interaction between the source of seed nut and site of nursery indicating the absence of manifestation of ecological adaptation at the seedlings nursery. The quality of the seedlings was enhanced by adequate soil water and high level of solar radiation on the nursery beds. The subsequent peerformance of these seedlings would have followed up after field planting to confirm the assumptions on adaptation discussed.Item River sand as an alternative to top soil for raising coconut seedlings in polybags(CRI, 1991-93) Peries, R.R.A.; Everard, J.M.D.T.Item Studying genetic relationships among tea (Camellia sinensis L.) cultivars in Sri Lanka using RAPD markers(Tea Research Institute. Talawakelle, 2005) Mewan, K.M.; Liyanage, A.C.; Everard, J.M.D.T.; Gunasekare, M.T.K.; Karunanayake, E.H.Item Varietal classification of New Coconut (Cocos nucifera L.) forms identified from southern Sri Lanka(Coconut Research Institute. Lunuwila, 2010) Ekanayake, G.K.; Perera, S.A.C.N.; Dassanayake, P.N.; Everard, J.M.D.T.
