NECTARINE TREE Filed Nov. 6, 1956 1,652 NECTARINE TREE Application November 6, mesa... 620,781

1 Claim. '(Cl..47i 62) The present invention relates to a new and distinct variety of nectarine tree of the yellow-fleshed, freestone, fruit-bearingtype, which'was originated by me as the result of planting seed obtained from open-pollinated flowers on an unnamed and unpatented peach variety which in turn was produced from a cross of an unnamed and unpatentedpeach seedling of Goldmine nectarine (unpatented) Rio Oso Gem peach (Plant 'Patent No. 84) and an unnamed and unpatented peach seedling of Goldmine nectarine X July Elberta peach (Plant Patent No. 15). a I 1 The primary objective of this breeding was to produce a new and improved nectarine variety having the fruit size and quality of the peach varieties constituting its antecedents.

The parent of my new nectarine variety was a wellcolored, medium-sized, yellow-fleshed, freestone peach having a medium chilling requirement and ripening about mid-August in southern California.

The objective of this breeding, as noted above, was fully achieved in mynew variety, as evidenced by the following unique combination of outstanding features:

(1) Large, yellow-fleshed, freestone fruit;

(2) High red blush of fruit skin, particularly on the side exposed to the sun;

(3) A low to medium winter chilling requirement, falling between Panamint nectarine (Plant Patent No. 1,100) and Silver Lode nectarine (Plant Patent No. 1,023) as observed in southern California; and

(4) A ripening period in mid-August approximately 4 to 5 weeks after Panamint nectarine.

In comparison with its parent variety, my new nectarine H differs therefrom primarily in being a nectarine,whereas the parent is a peach. It differs from its ancestral peach varieties Rio Oso Gem" and July Elberta by being somewhat smaller than either, having a higher skin color than either, and being a nectarine instead of a peach. It also differs from Goldmine nectarine primarily by being somewhat larger and being yellow-fleshed, whereas Goldmine nectarine is white-fleshed. In respect to ripening dates, my new nectarine ripens about 3 weeks after July Elberta in southern California; about in the same period as Rio Oso Gem; and about a week to days after Goldmine nectarine.

The foregoing characteristics and distinctions definitely ditferentiate my new variety from its parent, as well as from all other varieties of which I am aware, and asexual StatesPatet reproduction of the new variety by grafting, as performed I and both exterior and sectional views of the fruit being shown, all as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new variety, as based upon observations of specimens grown at Ontario, California, with color terminology in accordance with Robert F. Wilsons Horticultural Colour Chart, except where color terminology is given from Ridgways Color'Standards and Nomenclature (hereafter abbreviated as Ridgway) or where general color terms of ordinary dictionary significance are obvious:
