  • Patent number: PP8440
    Abstract: Disclosed is an apple tree having a strong vigor, long and narrow leaves, and bearing a slightly small fruit maturing earlier than "Tsugaru". The fruit has a conical to rounded-conical shape, and a deep red to deep reddish orange (ISCC - NBS) skin. The flesh of the fruit is yellowish (ISCC - NBS) white, juicy and has a moderate texture, and further, has a moderate sweet and sour taste. The fruit of the present apple trees ripen for eating and can be picked earlier than other early maturing varieties, thereby providing the fruit with an excellent market value, in particular, in mid-summer.
