Abstract
Disclosed is a Japanese pear tree bearing fruit with light green yellow skin, having a strong vigor, a stout shoot and a long internode, a high resistance to scab, and a high productivity. This tree produces a circular-ellipse-shaped fruit which matures early in the season, i.e., from the middle to the end of August, in the central part of the Kanto district, Japan. The fruit has a medium size and the same weight as "Chikusui", i.e., 250 to 300 g, and a yellowish white flesh which is soft, crisp and very juicy with a high Brix, the pH of the juicy being about 4.7-4.8, and little aromatic flavor, thus having an excellent dessert quality.
