Abstract:
Chlorophyll-a, chlorophyll-b, and carotenoids are vital components of the plant photosynthesis system and directly influence the yield and quality parameters of the tea plant. We measured chlorophyll-a, chlorophyll-b and carotenoids in radiated tea population. About 134 gamma-radiated induced tea populations were used for the estimation of photosynthetic pigment (Chl-a, Chl-b, and Car.) and their categorization as low, medium, and high basis. Contents of chl-a, chl-b, and car. varied significantly between tea planting materials. The correlations among the characters were significant and positive. This study is an attempt to indicate the available variation of the chlorophyll component of the radiated tea population and its categorization as low, medium and high. Based on the these preliminary data, our present study attempted to reveal various level of chlorophyll component in tea population and its application for developing the breeding strategies for the development of new tea varieties. It has also strongly suggested that induced radiation have ability to create variation in the photosynthetic component of tea planting materials.
