| Abstract: |
A new and distinct variety of plum tree to be known as the "Sweet Heart" which is most closely similar to the well known Casselman Plum Tree from which it is distinguished by pink rather than white blossoms, large leaves, and larger fruit. |
| Claim: |
Having thus described and illustrated my new variety of plum tree, what is claimed as new and desired to be secured by Letters Patent is:
1. A new and distinct variety of plum tree substantiallyas illustrated and described, characterized by similarity in tree and fruit characteristics to the well known Casselman variety of plum tree but distinguished therefrom and characterized as to novelty by having larger leaves and producing larger fruithaving smaller seeds, and thicker skins conducive to superior shipping and storage capabilities as compared with the Casselman Plum Tree. |
| Description: |
BACKGROUND OF THE NEW VARIETY
The present invention relates to a new and distinct variety of plum tree which has been named Sweet Heart.
The new variety is broadly characterized by bearing fruit which is substantially similar to that produced by the Casselman Plum Tree (unpatented) with which it ripens at approximately the same time but from which it is distinguished by blossomswhich are light pink as distinguished from the white Casselman blossoms. The new variety has larger leaves than the Casselman, produces larger fruit which is thick-skinned and can be picked at the same time as the Casselman. The fruit of the subjectvariety stores and ships excellently, has smaller seeds, and ripens uniformly so that the entire crop can be picked at one time. The new variety has a much longer picking season and can be permitted to remain on the tree much longer than the Casselman.
ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY
For many years, the applicant has sought to produce improved varieties of stone fruit by cross-pollinating blossoms of selected trees of desired characteristics. Pursuant to such objective, the applicant endeavored to cross the Casselman PlumTree (unpatented) with the Wonderful Pomegranate Tree (unpatented). What resulted may have unintentionally resulted in crossing a Casselman Plum Tree with a Casselman Plum Tree.
The applicant performed the cross-pollination on his farm at 269 W. Sycamore, Reedley, County of Fresno, Calif. The cross-pollination was performed by the applicant in 1978. The applicant was seeking trees of smaller stature which would beeasier to pick. His efforts to cross the Casselman Plum with the Wonderful Pomegranate produced eight seeds. The applicant succeeded in germinating six of the seeds which he planted on his farm and grew until he could determine the characteristics ofthe progeny. The subject variety was noted to have improved characteristics, as hereinafter described, and was asexually reproduced by the applicant on the same farm by budding the new variety into several Santa Rosa Plum Trees (unpatented). The buddedtrees were carefully observed by the applicant and determined to have the same characteristics as the original seedling that had been selected.
SUMMARY OF THE NEW VARIETY
The instant variety of plum tree is characterized by perpetuating the general tree and fruit characteristics of the Casselman variety of plum tree and which bears fruit which ripens at approximately the same time as the fruit of the CasselmanPlum Tree but which is distinguished from the Casselman and characterized as to novelty by having larger leaves, larger fruit, smaller seeds, and thicker skin than the Casselman variety.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying drawing is a color photograph of four whole plums of the subject variety, two being polished and two having the bloom remaining thereon, another plum of the present variety sliced on the suture plane together with a twig showingcharacteristic leaves of the subject variety and a further twig having the leaves removed therefrom to show stem coloration.
