Breeding of low-chill peach varieties with high eating quality<\/strong><\/p>\n\n\n\n

Laboratory of Fruit Crops, Faculty of Agriculture, Kagawa University registered the white-fleshed variety \u2018KU-PP1\u2019 in 2014 and the yellow-fleshed variety \u2018KU-PP2\u2019 in 2016. These were selected from the cross-seedlings between the peaches of subtropical origin, which have lower chilling requirement for breaking bud dormancy in winter, and Japanese high chilling peaches, which have excellent eating quality.<\/p>\n\n\n\n

These varieties have much lower chilling requirements than ordinary varieties. This allows them to flower two to three weeks earlier than ordinary varieties and to ripen fruit earlier, resulting in harvest in mid-June, the same time as very early varieties. The new variety has a higher sugar content due to the earlier flowering and longer growing period of the fruit.<\/p>\n\n\n\n

Fruit of these varieties harvested in early June are less susceptible to night moth damage and high temperature stress in summer. In addition, earlier release from bud dormancy of these varieties enables the early forcing culture in greenhouses, and adaptation to the conditions of warm winter due to global warming.<\/p>\n\n\n\n

Currently, growers in Okayama, Aichi, and Chiba prefectures are conducting economic cultivation or test planting.<\/p>\n\n\n\n
