Abstract

Among tea growing regions in Sri Lanka, lower elevations, popularly known as “Low Country” contributes about two third of the total tea production of the country. Through a series of experimentation, five new tea Camellia sinensis (L.) accessions (84, 174, 278, 12/11, 23/5) have been identified as candidate cultivars of TRI 5000 series, suitable for the region. All these accessions possess compatible yield potential with standard cultivars. Moreover, all of them possess high tolerance level to drought and 2-3 other desirable attributes, in terms of tolerance to major pests (shot hole borer, nematodes and low country live wood termites) and disease (stem and branch canker), prevailing in the tea cultivations of the region. In addition 02 of these accessions have exhibited moderate amenability to mechanical harvesting. These desirable attributes in terms of productivity and resilience of the new accessions will provide better opportunity to growers in the region to face emerging challenges including climate change effects, mainly prolonged dry weather and scarcity of skilled workers.
