CHERIMOYA TREE Filed Sept. 1l, 1944 .A Fleet Paris milication yseptember 11, 1944,- serial 1%'.553354 101211111. (Cria-62j.

' The present discovery relates to a new and distinct variety of cherim'oya,` a subtropical' fruiting Atree well known in California, This new variety originated as a seedling grown on my property at Whittier,` California, the iirs't asexual propagation fruiting in the season of"194 l,.

The' rst ripe fruit of the presentjvariety for this years season was picked about January -lst and the last ripe fruit was picked'about May' 1st. It is characterized 'as' to noveltyl by many distinctions, among the more importantfof which'k maybe mentioned the characteristic of the original tree of'a much greater'y quantitypi fruit produced without' hand pollination over along-period of tests and a muchgreater uriiio'rrziity-V and distinctiveness of flavor and', eatingl., quality throughout the entire' ripening season',"as compared with other existing cherimoyavarieties.

In further comparison with other varieties, the present one has a uniform shape where the yfruits result from open pollination and ythe tough and medium thick skin and vits 'smooth surface make it a more suitable fruit for shippingand han`- dlingwithout injury and Isubsequentdeterioration., J t 'Another'. importantcharacteristic is the abil ity'of the fruitof this variety@l when picked in the early part of the ."naturinseason, to ripen and come to full Liiavor afterthe picking even when the fruit picked is 'very'immature'asdistinguished' from .the habit of other varieties picked at that period when immature of merely hardening and solidifying.

stables; fixed, by @heerst fr un Petiole.-Medium long, medium thick; colory near Spinach Green (0960/3, p. 187); grooved on upper side and covered with =f Fruit Observed and described from February 1 to 7, 1944, as soon as soft enough to yield to firm pres sure. Fruit tested, ripened under room temperatures in from five to seven days after picking.

Size: While variable, more uniform in size than'v most cherimoya varieties, typical fruit measuring in Aaxial diameter, 3 to 3%, inches, transverse diameter, 3 to 3% inches, maximum `diameter, 31/2 to 4 inches. Weight, 7 to 12 ounces in uniformly shaped fruit, 12 ounces being approximately maximum size.

Form: Uniform while unsymmetrical, the fruits more nearly approach symmetry than do most other varieties of cherimoyas; commonly heart shaped, sometimes ovoid.

Rasa- Usually symmetric showing shallow.

channeled depressions which gradually disappear as they progress toward the apex at about of the distance from the base to the apex. Ayaan-Rounded, usually with faint markings and with no pistil point differentiation. Stern: Length 1 to 11/4 inches, medium stout; heavily pubescent. Mature fruits are easily detached at a cleavage point between the 'stem and the branch as soon as the fruit is sufllcient- 1y mature for harvest.

\ Colon-Parallel stripes of young bark tissue approaching Sage-Green (000861/1, p. 198) and more mature .tissue Leek Green (000858/2, p. 197). i

Skin: Medium thick, comparatively smooth, peels free of the flesh more readily than most cherimoyas and yields readily under the pressure of the thumb when ripe. No tendency to crack has been observed. Surface is nely pubescent which becomes less conspicuous at maturity. A pattern of lines much as the effect of outlines of imbricated scales are present on the surface of the skin although it is not actually scales. These scale-like appearing depressions vary in size and form, sometimes of a pentagonal or hexagonal shape with a less distinct outline toward the apex, being much'- more noticeable and depressed at the base. Near the base, inside the pattern of these lines there are rtypically depressions from which small tubercles emerge marking the location of the carpels on the inside of the fruit. Colorof the skin when rst ripening is near Fern Green (0862/ 1, p. 186) gradually changing to Fern" Green (0862/2) to Fern Green (0862/3). Atcomplete maturity it is colored with short, narrow stripes of Garnet Brown (00918/3, p. 192). They appear iirst along the lower border of these line patterns, and progress upward in each of the small sections. Very tiny Garnet Brown (00918/3, p. 192) lspots are distributed all over the fruit at this stage. The inside skin color near Scheeles Green (860/3, p.

FleshzAs observed from an axial diameter section color from skin towards center: Region near skin approximately 1A; of an inch wide, is Barium Yellow (503/2, p. 183). Remainder of the flesh near Naples Yellow (403/1, p. 121). As the fruit ages, the central portion surrounding the removable core, or the. elongation of the stem, is from Persimmon Orange (710/1, p. 91) to an undertermined brownish vhue. This color shades out in the surrounding esh to afaint Mimosa Yellow (602/3, p. 143). Surface of the seed cavity is smooth, semi-shiny. The coloris Mimosa Yellow (602/3, p. 143).

, Textura- Very fine, semi-fibrous surrounding the seed cavity, very nely gritty close rtothe skin. Ripens very evenly and would be classed as equal to or superior in texture to other well known varieties., Flavor.-Characteristically distinctive and delicious throughout the ripening season.

A delicate and desirable ksweet sub-acid taste.

Sugar content-As much as 26.51% of the dry weight.

ally about 3.3.

Size-Medium. Lengthv t0 3A inches;

width to 11s inches. Form.-Elongated, convex with two broad sides.

Base.-Truncate at hilum. Hilum acute pointed, slightly depressed adjacently.

Apen-Rounded, sides bounded by a bordering demarcating line, y

Surface.-Glabrous, smooth.

Hilum.`-Concavity with definite Majolica Yellow (09, D. 102) borders. Irregular interlaced lines or stripes of Majolica Yellow (O9/1, p. 102) color are often present on the darkbrownish seed surface. Use: Market and dessert. f Keeping quality: Best. Shipping quality: Best. General characters:

Crop production.-Heavy to medium. Bearing habit-Fruit both isolated and in clusters of two to ve or six, f I claim: .g

A newv and distinct variety of cherimoya tree,

characterized as to novelty, in comparison with other cherimoya varieties grown under comparable conditions, by the much greater production of fruit produced without hand pollination, much greater uniformity and distinctiveness of'avor and eating quality throughout the entire ripening season, uniformity of shape of the fruit, much greater suitability for shipping due to smooth surface and toughness of skin, the habit of ripening and coming to full flavor of fruit picked before maturity during'the early part of the maturing season, the high sugar content and low seed content of fruit grown from open pollination, substantially as shown and described. y.
