In order to select pollinizer varieties of high fruit qualities with large sized and high soluble solid contents, ‘Nishimurawase’ was crossed with ‘Johongsi’ at the Pear Research Institute, National Institute of Horticultural & Herbal Science in 2000. Among these crossed seedlings, ‘00-16-121’ was selected primarily in 2007, and it was finally selected since it was worthy of not only a pollinizer but also ripen and dried persimmon and named ‘Partner’ in 2009. ‘Partner’ shows intermediate in growth habit and semi-spreading tree shape. It has plenty of male flowers and rich pollen amount with about 380 mg per one hundred flowers. The average optimum harvest time of ‘Partner’ was 144 days after full bloom and it matured around one week earlier than ‘Zenzimaru’ and three weeks later than ‘Nishimurawase’. The fruit is elliptic in shape and orange in skin color. Average fruit weight was 224 g, and soluble solids content was 18.8°Brix.
