Effects of freezing damage were investigated for several cultivar rootstocks and native selection of ornamental peach on withering and injury of trunks in 'Hakuho' and 'Shouwahakuto' peach trees. For 'Ohatsumomo' rootstock, injury occurred mainly in scions at 3 years old; plants died at 4 years old. In contrast, for 'Peach tree rootstock Tsukuba-1 'Harrow Blood', and 'Kokuhu HM-1' rootstocks, injury occurred in scions and rootstocks at 3-4 years old in some trees, but the plants did not die. 'Kokuhu HM-1' was the most tolerant to cold injury in four rootstocks examined. It was inferred to be effective for avoiding injury. The period of bud break, flowering and leafing showed little difference. Vigor of trees did show a difference, but its relation to injury was not clear.
