A new cultivar 'Yumekaori' for green tea was bred at the Tea Branch Facility, Miyazaki Agricultural Research Institute and registered as Cha Norin No.54 by the Ministry of Agriculture, Forestry and Fisheries in October, 2006. This cultivar was selected out of seedlings crossed between 'Sayamakaori' and 'Miyazaki No.8' in 1986. 'Yumekaori' is the first cultivar in Japan which was bred for the resistance to Pseudaulacaspis pentagona (Targioni-Tozetti).
The characteristics of this cultivar are as follows ;
This cultivar is early budding, the plucking time of the 1st crop is about 4 days earlier than in 'Yabukita'. The shape of the plant is intermediate type and the growth is slightly vigorous.
This cultivar is slightly susceptible to tea anthracnose (Colletotrichum theae-sinensis (Miyake)Yamamoto) and tea blister blight (Exobasidium vexans Massee). But it is fairly resistant to tea gray blight (Pestalotiopsis longiseta Spegazzini). This cultivar is more resistant to P pentagona than 'Sayamakaori'.
It is fairly resistant both to cold damage in midwinter and to bark split frost injury in early winter. The yield of green leaves of this cultivar is higher than that of 'Yabukita'. The quality of processed tea is very good, the aroma is fresh and the taste is body.
