Definitions

  • the present invention relates to a new and distinct variety of peach tree of the yellow-fleshed, freestone fruitbearing type which was originated by me by crossing two unnamed and unpatented varieties, each derived from an extended series of crosses beginning with an initial cross of Early Imperial (unpatented) by Coolidge Double Red (unpatented) in the case of one parent, and beginning With Rio Oso Gem (Plant Patent No. 84) by Lukens Honey (unpatented) in the case of the other parent.
  • the primary objective of this breeding was to produce an improved peach variety, and this objective was fully achieved with the resultant combination'of the most desirable characteristics of the two parent varieties, along with other desirable features.
  • my new variety is particularly characterized as to novelty by its vigorous and upright growth, its relatively low winter-chilling requirements and attendant high and regular productivity in climates corresponding to that of Southern California, its large double blooms of medium pink color which are borne from 1 to 4 flowers per node, with the nodes relatively closely spaced and giving a distinct ornamental appearance to the tree during the blooming period, its large, round fruit of relatively firm texture and consequent good handling qualities, and the delectable flavor of its fruit.
  • the fruit of my new variety ripens from early July to mid-July, whereas the fruit of this parent ripens from late July to early August, and the blooms of the new variety are large in size, double in petalage and a medium shade of pink color in contrast to the medium sized blooms, usually single petalage and light pink color of the blooms of this parent.
  • the flesh of the fruit of my new variety is yellow and of relatively firm texture, whereas that of the parent variety is white and of relatively soft texture, and the fruit of the new variety has flesh which is free from the pit or stone instead of clinging to the stone like the flesh of the fruit of this parent.
  • the ripening season of my new variety is from about one week to ten days later than that of the Babcock peach (unpatented), which is one of the most well-known varieties in Southern California, and the chilling requirements of the new variety are even somewhat less than that of the Babcock peach which is known to require little winter-chilling in Southern California.
  • Dates first and last picking Vary somewhat from yearto-year because of varying winter-chilling in Southern California, but usually begin picking about July 7 to July 24, ending about July 17 to August 4, depending on the season.
  • Tree Large; vigorous; upright; dense; vase-formed; productive; regular bearer.
  • Trunk.Stocky from medium to shaggy in surface roughness.
  • Petiole medium length from inch to /2 inch long; from medium to thick caliper. Glands-average 3 in number; alternate; reniform; medium size; usually positioned on petiole at attachment of leaf blade and rarely on leaf blade near petiole. Color green.
  • Petalage.-Double usually from 14 to 16 petals, with l or 2 petaloids; from 1 to 4 flowers borne at each node, with nodes usually spaced from /2 inch to 1 inch apart on flowering branches, thus forming an almost continuous spray of flowers along each branch and giving the tree a definite ornamental appearance during blooming period.
  • Stone Free; adheres to flesh along both dorsal and ventral edges; short fibres; free on sides; retains short fibre-like threads in depressions of stone.
  • Ventral edge.-Thick with wing generally throughout.
  • Insect resistance Medium resistance to thrips, as determined by comparison with other varieties grown under comparable cultural conditions at Ontario, California.
