Abstract
Disclosed is a Japanese pear tree bearing fruit with yellow-reddish-brown skin; having good vigor, a stout shoot, high resistance to black spot disease, and high productivity. This tree produces circular-shaped fruit which mature late in the season (i.e., from the middle to end of October), in the central part of the Kanto district of Japan. This fruit is large, with an average weight of 607 g. The white flesh is soft, crisp, and very juicy. This flesh has a moderate Brix (the pH of the juice being about 4.32) and no aromatic flavor: thus, it possesses excellent dessert quality.
