Abstract

A new cultivar ‘Harunonagori’ for green tea was released on 2008 and it bred at the Tea Branch Facility, Miyazaki Agricultural Research Institute. ‘Harunonagori’ was selected out of seedlings crossed between ‘Saitama No.1’ and ‘Miyazaki No.8’ in 1986. <br>The characteristics of ‘Harunonagori’ are as follows ; <br>‘Harunonagori’ is late budding, the plucking time of the 1st crop is about 4 days later than in ‘Yabukita’. The shape of the plant is slightly spread type and the growth is slightly vigorous. <br>‘Harunonagori’ is resistant to tea anthracnose (Colletotrichum theae-sinensis (Miyake) Yamamoto) and fairly resistant to tea gray blight (Pestalotiopsis longiseta (Spegazzini) Dai et Kobayashi). But it is middle susceptible to tea blister blight (Exobasidium vexans Massee). ‘Harunonagori’ is more resistant to Pseudaulacaspis pentagona Targioni than ‘Yabukita’ and ‘Kanayamidori’. <br>It is fairly resistant to cold damage in midwinter and slightly susceptible to bark split frost injury in early winter. The yield of ‘Harunonagori’ is higher than that of ‘Yabukita’. The quality of processed tea is as good as ‘Yabukita’. The color and aroma of processed tea is better than that of ‘Kanayamidori’.
