‘Yumi’ is the eighth peach cultivar released by the Rural Development Administration (RDA) peach breeding program since 1962. The main purpose of this program is to breed new peach cultivars that can satisfy consumers with high fruit quality. This program has focused on sweet and good tasting fruit with long shelf life. ‘Yumyeong’ has good shelf life with firm flesh (Kim et al., 1978) and ‘Chiyomaru’ produces good-tasting and early ripening fruit (Yamaguchi et al., 1989). In the 1990s, these two cultivars were chosen as parents to breed new peach cultivars bearing high-quality fruit. The cross between ‘Yumyeong’ and ‘Chiyomaru’, the most successful combination in this peach breeding program, produced ‘Mihong’ (Jun et al., 2007a), ‘Misshong’ (Jun et al., 2013), ‘Soomee’ (Jun et al., 2007b), and ‘Yumi’.
Trees of ‘Yumi’ are medium vigor and productive without alternate bearing and have a high chilling requirement of ≈790 chill units. Flowers are showy and pollen is abundant. Fruit ripen 82 d after full bloom and fruit size is medium with average weight of 243 g. Fruit skin is striped with light red and flesh color is creamy white. Flesh is soft and melting with good quality. Red pigmentation is very weak in the outer flesh and around the pit. Flesh clings to the pit even when fully ripe. ‘Yumi’ is early maturing, attractive, and sweet fruit for the fresh market.
