Description

Examination of pubescence of young leaf was made on tea clones collected from China (270 clones), Japan (1, 241 clones), Taiwan (73 clones), India (567 clones) and other tea producing countries (295 clones).<BR>Twentythree patterns were classified based on width, length, density and distribution of leaf hair.<BR>As a whole, China tea clones belonging to var. sinesis showed narrower variation than Assam tea clones belonging to var, assamica. China tea clones had long hairs of high density distribution on entire surface of leaf. On the other hand, Assam tea clones had short hairs and medium/low density with limited distribution on the inner part of leaf lamina near to midrib.<BR>Only tea clones from Darjeeling in India, belonging to var. sinensis according to their small leaf, did not show the typical pattern of pubescence similar to China tea clones. This would suggest some influence by var. assamica on their pubescence pattern.<BR>Taiwan tea clones (Taiwan-Yamacha) had absolutely no hair on their young leaves. At present, Taiwan tea clones are included in var. assamica. But their pubescence patterns were revealed great difference with true pattern of var. assamica.
