*Corresponding author (shashiprabhag@yahoo.com) Tea (Camellia sinensis) is one of the principal export plantation crops in Sri Lanka. It has contributed 1.2% of GDP to the economy of the country in the year 2005. There are 64 tea cultivars recommended for commercial planting in Sri Lanka. However, most of the tea plantations contain only a few selected cultivars developed by Tea Research Insitute (TRI), such as TRI 2025. This drastically narrows the genetic diversity in commercial plantations and the breeding population. Therefore conservation of tea genetic resources and broadening the genetic base of the crop are pre-requisites for an effective crop management programme to ensure the sustainability of tea industry. The systematic assessment of genetic variability present in the germplasm collection provides an approach to identify parents based on true genetic differences. This is important in selecting parents for generating heterosis by hybridization.
