Abstract
The present invention relates to a peach tree, Prunus persica, and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, hardy, self-fertile, productive and regular bearing tree. The fruit matures under the ecological conditions described approximately the third week in June, with first picking on Jun. 18, 2001. The fruit is uniformly medium in size, very good in flavor, globose in shape, clingstone in type, firm in texture, white in flesh color, and full red in skin color. The variety was developed as a self pollinated seedling of ‘Ivory Princess’ (U.S. Plant Pat. No. 11,205) white flesh peach.
Description
Prunus persica.
In a continuing effort to improve the quality of shipping fruits, I, the inventor, typically hybridize a large number of nectarine, peach, plum, apricot, and cherry seedlings each year. In an effort to exhibit recessive traits, I also grow a lesser number of open pollinated seeds of each of these fruits. The present invention relates to a new and distinct variety of peach tree, which has been denominated varietally as ‘IVORY QUEEN’. The present variety was germinated by me in 1996 using embryoculture techniques in my laboratory, grown as a seedling on its own root in my greenhouse, and transplanted to a cultivated area of my experimental orchard at Bradford Farms near Le Grand, Calif. in Merced County (San Joaquin Valley). It ws developed as a self pollinated seedling of ‘Ivory Princess’ (U.S. Plant Pat. No. 11,205) white flesh peach. Subsequent to origination of the present variety of peach tree, I assexually reproduced it by budding and grafting in the experimental orchard described above, and such reproduction of plant and fruit characteristics were true to the original plant in all respects. The reproduction of the variety included the use of ‘Nemaguard’. Rootstock (unpatented) upon which the present variety was compatible and true to type.
The present variety is similar to its parent, ‘Ivory Princess’ (U.S. Plant Pat. No. 11,205) peach, by producing white flesh clingstone peaches that are globose in shape, firm in texture, and mostly red in skin color, but is distinguished therefrom and an improvement thereon by producing fruit that matures about 10 days later.
The accompanying photograph exhibits four whole fruits positioned to display the characteristics of the skin color and form, one fruit divided transversely to the suture plane to reveal the flesh and stone, and typical leaves.
Referring now more specifically to the pomological characteristics of this new and distinct variety of peach tree, the following has been observed under the ecological conditions prevailing near Le Grand, Merced County (San Joaquin Valley), Calif., and was developed at the state of firm ripe on Jun. 23, 2001, on the original tree during its fifth growing season.
