Plum tree &#34;Gar Jumbo&#34;
BACKGROUND OF THE NEW VARIETY 
     The present invention relates to a new and distinct variety of plum tree, which has been denominated varietally as &#34;Gar Jumbo&#34;, and which is broadly similar to the Autumn Rosa Plum Tree (patented), of which it is most closely similar, but from which it is distinguished therefrom in bearing fruit which is larger in size, deeper and richer in skin color, and having a heavier bloom. 
     The new variety is broadly characterized by bearing fruit that is most similar to the Autumn Rosa Plum Tree (patented) with which it ripens at approximately the same time, but from which it is distinguished therefrom by producing a plum which is significantly larger than the plum produced by the &#34;Autumn Rosa&#34; tree. 
     In an effort to upgrade his fruit products, the applicant is continuously on the alert to locate new varieties that might appear as sports or mutations on the fruit trees of any of his several farms. In the development of new and distinct varieties of plums, the applicant has germinated and grown thousands of randomly pollinated seedlings to maturity, and evaluated the resultant trees and their fruit. The subject variety is a result of his efforts in germinating the aforementioned seedlings. 
     The plum tree of the present invention is noteworthy for the larger fruit that is produced, the deeper skin color, and the significantly heavier bloom, than that produced by the &#34;Autumn Rosa&#34; variety. 
     ORIGIN 
     The present variety of plum tree was a seedling of unknown parentage grown in the seedling nursery at the inventor&#39;s ranch located at Kings Canyon Road and Fowler Avenue, Fresno, County of Fresno, State of California, in 1977. The seedling was observed for several years prior to recognition of its desirable characteristics. The applicant asexually reproduced the subject plum by budding the new and distinct variety to seedling trees which were planted at the applicant&#39;s orchard designated as Ranch No. 3, located at Belmont Avenue, Fresno, County of Fresno, State of California. This first asexual reproduction was performed in 1981. The resultant progeny were found to possess the same distinctive characteristics as the original seedling. 
    
    
     BRIEF DESCRIPTION OF THE DRAWING 
     The accompanying drawing is a color photograph of a characteristic twig bearing typical leaves, two plums are shown displaying their external coloration, one of such plums having the bloom removed to show the distinct coloration at maturity, a plum is halved transversely of the suture plane to illustrate the flesh coloration and stone characteristics of the subject variety.
