PEAR TREE Filed Oct. 24, 1944 Patented Mar. 25, 1947 Plant Pat. 728

UNITED STATES PATENT OFFICE 1 Claim.

The present discovery relates to a new and distinct variety of pear tree, originating as a chance seedling, that I found to have important characteristics distinguishing it from other known commercial varieties. These characteristics appear to be a combination of all the good qualities of both the Bose and Clapps Favorite, and this new variety might Well be presumed to be the progeny of these well known pears. However, the parentage is not known aside from this presumption.

One of the most important features of novelty of this new pear is its resistance to blight and to the devastating action of pear psylla. This was observed by me, speaking with reference to the original seedling, which was grown among a group of Seckel, Bose, and Clapps Favorite trees, when the seedling showed no psylla injury while the surrounding varieties lost most of their foliage due to psylla.

The applicant has grafted 100 trees by top working, and has root grafted about 200 seedlings, to reproduce asexually this variety. From observation over a period of three years, said trees and progeny have been and are free of pear psylla and fire blight, although other pear varieties in the same orchard have been afiiicted with these diseases.

The new variety is much more vigorous than any variety I have ever seen. It is also as productive as Clapps Favorite, but somewhat larger in size and longer in shape, resembling the Bose variety in this respect, but in color it is more nearly like Clapps Favorite,

Top working of this variety shows that the characteristics referred to and disclosed more in detail hereinafter are established and come true to form.

The accompanying illustration shows a number of specimens of this new variety taken about two weeks before maturity and arranged in different positions to illustrate their uniformity and other physical characteristics as nearly as these can be presented by illustration.

The following is a detailed description of the new variety, color terminology according with ordinary dictionary definition.
