  • Publication number: 20110191918
    Abstract: The new ‘HBOK 32’ rootstock, a hybrid between two peach parents, is useful as a commercial under-stock for peach and nectarine cultivars. The stock has been successfully propagated clonally by leafy cuttings and tissue culture. This rootstock imparts significant vigor control to the scion cultivar that is propagated on top of it. This rootstock produces very few root suckers, its anchorage is good and it is resistant to root-knot nematode. Utilization of adapted growth controlling rootstocks in commercial orchard situations reduces the height of the tree and the amount of wood pruned in the winter and summer, without compromising the quality of the fruit. This in turn increases the efficiency of various cultural operations such as pruning, thinning and harvesting by reducing the need for workers in the field to use tall ladders when carrying out these operations.

  • Publication number: 20110154547
    Abstract: A new and distinct variety of peach rootstock denominated ‘HBOK 50’ is described. The ‘HBOK 50’ peach rootstock offers size control ability, root knot nematode resistance, less wood from dormant and summer pruning, and production of fewer root suckers. ‘HBOK 50’ has contributed to size reduction of compound trees when it is used as a clonally-produced rootstock with the fresh market peach “O'Henry”. No evidence of graft incompatibility or other abnormalities have been noted in such circumstances. Fruit on compound trees with ‘HBOK 50’ rootstocks is either similar in size or smaller than ‘Nemaguard’. The ‘HBOK 50’ rootstock displays root knot nematode resistance levels similar to ‘Nemaguard’ and more resistant than ‘Lovell’.

  • Publication number: 20110154548
    Abstract: The new ‘HBOK 10’ rootstock, a hybrid between two peach parents, is useful as a commercial under-stock for peach and nectarine cultivars.

  • Patent number: PP15547
    Abstract: A new prune cultivar designated ‘D6N-72’ has been developed. The new cultivar is the result of a cross between ‘Improved French’ and ‘Tulare Giant.’ The fruit of this cultivar are large, light purple to light bluish purple in color and covered with a grayish waxy bloom. The ‘D6N-72’ tree is productive and a regular bearer.

  • 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. The fruit is particularly well suited for the fresh prune market.

  • 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: 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: PP23631
    Abstract: The new ‘HBOK 27’ rootstock is an ‘OP-F2’ plant from an F1 plant of an intraspecific hybrid between two peach parents that is useful as a commercial under-stock for peach and nectarine cultivars. The ‘HBOK 27’ rootstock has been successfully propagated clonally by leafy cuttings and tissue culture. The ‘HBOK 27’ rootstock is graft compatible with peach scion cultivars, and confers moderate vigor control to the compound trees. Peach trees grown on the ‘HBOK 27’ rootstock are productive, require less pruning than trees on grown on the standard rootstock ‘Nemaguard’, and produce fewer root suckers than ‘Nemaguard’. The ‘HBOK 27’ rootstock shows moderate resistance to root knot nematode [Meloidogyne incognita (race 1) isolate ‘Beltran’] that is slightly less than that of the standard rootstock ‘Nemaguard’.
