Abstract

A pear tree, which is a planned cross between Max Red Bartlett and Comice is characterized by its heavy crop of large red-skinned fruit of excellent dessert quality which have long storage life.

Description

BACKGROUND AND SUMMARY OF THE INVENTION
This invention relates to a new and distinct variety of pear tree, which was the result of a planned cross between the Comice (unpatented and the pistillate parent), and the Max Red Bartlett (U.S. Plant Pat. No. 741).
The new pear variety originated at the Southern Oregon Agricultural Experiment Station located near Medford, Oreg. from controlled crosses made by the inventor in or about the year 1940. The subject variety has several qualities which now are in demand in the pear industry, such as the ability to crop heavily and regularly, provide large, attractive, red-skinned fruit of top dessert quality, and produce fruit that possess long storage life for fresh market and gift market needs. The subject plant bears large-fruited red pears which are particularly suited for the holiday and late winter markets. Its fruit has excellent dessert quality and it possesses an attractive, bright, glossy red blush appearance when displayed on shelves and in gift boxes. It has a storage life of up to eight (8) months when properly stored.
The subject variety has been asexually reproduced and subsequent second and third generations of trees have been tested thoroughly and evaluated at the Southern Oregon Agricultural Experiment Station over the past twenty-eight (28) years.
BRIEF DESCRIPTION OF THE DRAWINGS
FIGS. 1, 2, 3 and 4 show the fruit of the subject variety in comparison with the fruit of its parents.
FIG. 5 shows a typical leaf of the subject variety in comparison with the leaves of its parents.
FIG. 6 shows a twig of the subject variety in comparison with the twigs of its parents.
FIG. 7 shows spur growth of the subject variety in comparison with the spur growth of its parents.
GENERAL DETAILED DESCRIPTION OF THE INVENTION
Trees of the subject variety growing on Pyrus communis seedling rootstocks are vigorous and upright in growth. Cropping is heavy and regular in mature trees. In comparison with both of its parents, the subject variety is distinctively characterized as follows:
(1) The bloom period of the subject variety follows the bloom period of Max Red Bartlett by several days but is slightly ahead of the bloom period of Comice, overlapping both of its parents. It is not self-fruitful but can effectively be cross-pollinated with pollen from either of its parents.
(2) Fruit maturity and harvest dates of the subject variety follow those of Max Red Bartlett by about 10 days. Its fruit should be harvested about 10 days ahead of its other parent, the Comice variety.
(3) Its storage life exceeds that of Max Red Bartlett by at least four months and Comice by two months.
(4) Few stone grit cells have been observed in the fruits of the subject variety like the flesh of its parents.
(5) Its fruit shape is intermediate between Max Red Bartlett and Comice, being plump in the distal portion with a recessed calyx, while maintaining a distinct shoulder and moderately tapered neck.
(6) Cropping is heavier in the subject variety than either Max Red Bartlett or the red sport of Comice. (See the following table.)

Growth habit is similar to its pollen parent the Max Red Bartlett. Leaves, twigs and spur growth are similar to both of its parents, except for the noticeably darker bark and the conspicuous, large, raised tan-colored lenticels on second year twigs. Both of its parent possess smooth, less-conspicuous lenticels on twigs of the same age.
