eHarumidorif was bred of the Makurazaki Station of the National Research Institute of Vegetables, Ornamental Plants and Tea (presently National Institute of Vegetable and Tea Science) and was registered by MAFF as Cha Norin No. 48 in August, 2000. eHarumidorif is a late budding and high-yielding cultivar with good quality for eSenchaf a kind of green tea. This cultivar was selected out of the progenies crossed between eKanayamidorif (seed parent) and eYabukitaf (pollen parent) in 1972. The characteristics of this cultivar are as follows: The plant shows a spreading type. The growth is vigorous and the yield is higher than that of eYabukitaf at the mature stage. The cultivar is fairly resistant to tea anthracnose caused by Gloeosporium theae-senensis. The resistance to blister blight caused by Exobasidium vexans is intermediate and the cultivar is susceptible to tea gray blight caused by Pestalotiopsis longiseta. Since green leaves are soft in touch even after the youngest shoots reach the banjhi stage, it is easy to process them to good tea. Tea quality is very high for eSenchaf due to the low tannin content and high content of amino acids. eHarumidorif is highly resistant to bark splitting injury because the autumn growth stops very early. eHarumidorif is suitable for all the tea production areas in Japan.
