  • Publication number: 20030009796
    Abstract: A new and distinct cultivar of early-season clingstone peach tree (i.e., Prunus persica) is provided. Attractive fruit is formed that is well suited for processing having uniform yellow flesh that is free from red staining at the pit cavity. The fruit color, flavor, and texture are believed to be superior to the ‘Dixon’ and ‘Andross’ cultivars (both non-patented in the United States).

  • Patent number: PP12224
    Abstract: A new and distinct cultivar of prune tree (i.e., Prunus domestica) is provided that resulted from a controlled breeding program. The new cultivar exhibits extreme precocity and a vigorous growth habit. Flowers are formed in abundance. Very large early-maturing fruit also is formed in abundance on a regular basis that is dark purple under a greyish and waxy epidermal bloom.

  • Patent number: PP12398
    Abstract: A new and distinct cultivar of prune tree (i.e., Prunus domestica) is provided that resulted from a controlled breeding program. Quality early-maturing fruit is formed that is particularly well suited for the dried fruit market. The tree is regular bearing and vigorous. Dark purple fruit with a medium waxy bloom is formed that, when compared to the fruit of the ‘Improved French’ cultivar (non-patented in the United States), is larger, matures approximately 7 to 10 days earlier, and possesses a lighter, more complex fruity taste with a higher sugar content. The fruit stone is nearly free and machine pits well.

  • Patent number: PP6759
    Abstract: A new and distinct variety of Peach tree which is somewhat remotely similar to the Gemfree Peach Tree (U.S. Plant Pat.

  • Patent number: PP9438

    Inventor: James F. Doyle
  • Patent number: PP11208
    Abstract: A new and distinct cultivar of peach tree (i.e., Prunus persica) is provided that originated as a scaffold mutation of unknown causation of the `Ross` cultivar (U.S. Plant Pat. No. 4,863). The new cultivar forms attractive fruit that is well suited for canning which matures approximately ten days later than that of the parent `Ross` cultivar. Commonly a distinct red stripe is formed on the suture line of the fruit. All other characteristics of the new cultivar are believed to be substantially identical to those of the `Ross` cultivar. The later fruit maturity offers fruit growers and canneries more flexibility in the harvesting and canning of the fruit crop through the simultaneous growing of the `Ross` cultivar and the new cultivar of the present invention without sacrifice of fruit quality.

  • Patent number: PP11403
    Abstract: A new and distinct cultivar of Marianna rootstock that originated as an open-pollinated seedling is provided. The new cultivar is particularly well suited for use as prune rootstock. When compared to the previously utilized Marianna `2624` cultivar, it is found that the new cultivar exhibits superior root anchorage and a significantly reduced tendency to form unwanted suckers. Also, the new cultivar when compared per se to the Marianna `2624` cultivar is found to set considerably more fruit, to form smaller fruit, and to possess a pit that is considerably smaller. Good wet soil tolerance is exhibited. The new cultivar propagates well by the use of cuttings.

  • Patent number: PP34871
    Abstract: The ‘S-54’ fig tree is a common-type fig tree, characterized by high vigor, precocious growth, and abundant production of large yellow to yellow-green figs. ‘S-54’ figs have a very small, closed eye that restricts the entrance of insects and spores that may cause internal decay or unwanted pollination. The skin of ‘S-54’ figs is moderately thick and durable, making the fruit well-suited for packing and shipping as a fresh market product. The fruit pulp is an attractive red color, has fine texture and is sweet and rich in flavor.
