Tea [Camellia sinensis (L.) O. Kuntze] is one of the most popular and lowest cost beverages in the world, and consumed by a wide range of age groups in all levels of society with more than three billion cups daily worldwide. Tea breeding strategy such as source of gene pool, selection of elite mother bushes and assessment of made tea quality reviewed. Tea research achievement in breeding, eco-physiology, and biochemical; production of tea in China, India, Kenya, Sri Lanka and Vietnam was considered. The challenges like mini-manufacture, cost assessment, climate change, time consuming protocols, pest and diseases; cost of assessment including constraints of Ethiopian tea industry was reviewed well. Future prospects of tea research main research emphases of tea genetics and breeding in the future, deepening the functional genome research to reveal special gene resources, enhancing the basic genetic research for breeding, conducting distant hybridization to enhance germplasm innovation, improving gene transformation technique to use exogenous genes, Perfecting molecular marker assisted technique to effectively conduct early-stage appraisal and similar procedures should be integrated in the future tea research in order to cope up with the currently existing environmental phenomena.
