Item The heritability of raw rubber properties in a Hevea population(Rubber Research Institute of Sri Lanka. Agalawatta, 1997) Yapa, P.A.J.; Fernando, D.M.; Wickramasinghe, W.N.; Peiris, B.M.S.G.The heritability of raw rubber properties in a HEVEA population was studied and it was found to be low in the case of the population investigated. However some useful correlations between certain properties such as Wallace Plasticity, colour and mooney viscosity were observed.Item Need for uniformity in properties, novel uses challenges ahead for NR(Rubber Research Institute of Sri Lanka.
