  • the present invention relates to a new and distinct variety of peach tree which was originated by me by crossing an unnamed and unpatented peach seedling with the variety known as the Robin Peach" (Plant Patent No. 529), the former being the seed parent and the latter being the pollen parent.
  • the aforementioned breeding has produced an improved variety of peach tree of the whitefleshed. semi-freestone type which is particularly characterized as to novelty by its unique comblnation of a short winter-chilling requirement, a short maturation period, and a very early ripening date.
  • These qualities make the new variety especially suited to planting in Southern California and similar areas where it has the ability to produce a crop of fruit each year when winter temperatures are insufficient to satisfy the chilling requirements of standard varieties of otherwise similar type.
  • My new variety has a chilling requirement similar to that of the Babcock Peach (unpatented), but it differs from the latter variety by having a much shorter maturation period and by its habit of ripening at a much earlier date.
  • the fruit of my new variety is white-fleshed and semi-freestone, whereas that of its seed parent is yellowfleshed and freestone; my new variety ripens from 7 to 8 weeks earlier than the fruit of the seed parent, the former ripening from about the middle of May to late May at Ontario, California, whereas the parent variety ripens from about the middle of July to late July in the same location; and the fruit of the new variety is somewhat smaller in size than that of its seed parent.
  • My new variety differs from its pollen parent Robin Peach by usually ripening about 2 weeks earlier than the fruit of this parent, and sometimes even more early; the blooms of my new variety are non-showy, whereas those of this parent are showy in type; the color of the blooms of my new variety is deep pink, while the color of the blooms of this parent is light pink; the flavor of the fruit of the new variety is typied by a substantial balance of acid and sugar, whereas the flavor of the fruit of this parent is sub-acid and predominantly sweet; and the fruit of the new variety has more contrast in skin color by reason of its being blotched and mottled, whereas the skin color of the fruit of this parent is typically a more uniform pattern of overlay.
  • the accompanying drawing shows typical specimens of the fruit and foliage of my new variety, with both the upper side and the lower side of the foliage being illustrated, and the fruit being shown in elevation. and also in section both with and without the stone or pit.
  • Wilson Wilsons Horticultural Colour Chart
  • Ridgway Color Standards and Nomenclature
  • Dates of first and last picking- Vary somewhat from year-to-year because of varying winter chilling in Southern California, but usually begin picking about May l2 to June l, and ending about May 28 to June 10, depending on the season.
  • Tree Large to medium size; vigorous; upright; dense; Vase-formed; very productive; regular bearer.
  • Trunk Medium caliper in relation to length
  • Leaves Length 41/2 inches to 5% inches; width 11A inches to 'l1/2 inches; large; acuminate to lanceolate; medium thickness; relatively smooth; wavy type (as defined in article by Meader and Blake entitled Progress Report on Identification of Peach Varieties by Leaf Characterstics.” appearing in American Society for Horticultural Science Proceedings for 1939, volume 37, pages 203 to 207) Colon- Upper surface-between Deep Dull Yellow-Green (l) Plate XXXII (Ridgway) and Dark Dull Yellow-Green, Plate XXXII (Ridgway). Lower surfacenear chromium Green, Plate XXXII (Ridgway).
  • PetioIef-Medium length The PetioIef-Medium length; medium caliper.
  • Flower-buds Medium to small size; conicpointed; medium length; pubescent, with bud scales having yellowish pubescence and free portion of calyx having grayish pubescence on outside surface.
  • Stone Semi-free; adheres to flesh somewhat over entire surface when firm, but usually along only both dorsal and ventral edges when fully ripe; fibers long to medium; free usually on sides when fully ripe; fibers in depressions of pit.
  • ventral edge ventral edge.-Thick, with wing throughout.
  • a new and distinct variety of peach tree of the white-fleshed, semi-freestone fruit type substantially as herein shown and described. characterized particularly as to novelty by its short winterchilling requirement, by its short maturation period, and by its very early ripening date.
