A new cultivar of green tea ‘Haruto34’ was developed at the Tea Branch Facility, Miyazaki Agricultural Research Institute and released in 2016. ‘Haruto34’ was selected from seedlings of the crosses between ‘Saemidori’ and‘Sakimidori’, which were carried out in 1997.
The characteristics of‘ Haruto34’ are as follows :
‘Haruto34’ is extremely early budding and plucking time of the first crop is about two days earlier than that in ‘Saemidori’. The shape of the plant is of intermediate type and its growth is vigorous. ‘Haruto34’ is fairly resistant to tea gray blight (Pestalotiopsis longiseta (Spegazzini) Dai et Kobayashi), but it is susceptible to tea anthracnose (Discula theas-sinensis (I.Miyake) Moriwaki & Toy.Sato)and tea blister blight (Exobasidium vexans Massee). ‘Haruto34’ is vulnerable to mulberry scale (Pseudaulacaspis pentagona Targioni). ‘Haruto34’ is fairly resistant to cold injury damage in winter. The yield of ‘Haruto34’ is higher than that of ‘Yabukita’ and ‘Saemidori’. Sencha, Kamairicha to make with ‘Haruto34’ is high quality, as indicated by the bright green color of tea and mild aroma and taste. The amino acid content in the processed tea is high, whereas the tannin content is low. The covering cultivation of‘ haruto34’ around five days can greatly improve quality of the tea.
