‘Sakuhime’ is a new white-fleshed peach cultivar (Prunus persica (L). Batsch) which was released in 2018 by the National Agriculture and Food Research Organization, Institute of Fruit Tree and Tea Science in Japan. Selection was based on the criteria of agronomic performance, fruit quality and the reduced chilling requirement of seedlings obtained from a cross between 296-16 and 332-16. ‘Sakuhime’ was initially designated as Peach Tsukuba 127 and evaluated across 24 experimental stations in Japan during the 9th national trial of peaches (2010-2015). The final selected line was named ‘Sakuhime’ and registered as No.26635 under the Plant Variety Protection and Seed Act of Japan on 9th March, 2018.
‘Sakuhime’ trees grow vigorously and produce many self-compatible flowers. In our study, which was based in Tsukuba, flowering and fruit maturation occurred on approximately the 27th March and the 26th June respectively. The fruit was round to ovate in shape with an average weight of 253 g. The fruit skin ground color was greenish white with a high to medium degree of red blushing. It was sometimes observed to crack, the extent of which depended on location and year of fruit production. We suggest that this could be avoid by bagging developing fruit on the tree. The clingstone flesh was creamy-white colored with a melting texture. Its juice had a pH of 4.6 and a soluble solids content of 12.8%. ‘Sakuhime’ has a lower winter chilling requirement (555 chill hours; CH) than the current major peach cultivars grown commercially in Japan (1,000-1,200CH). This could be advantageous in the production of peaches in areas which have warmer winters and could be important on a wider scale as a response to changes associated with climate change.
