Nectarine tree name Prita
This invention relates to a new and distinct variety of nectarine tree. 
     The new variety was discovered in 1984 by Jean-Pierre Darnaud, Jean Prim and Gabriel Tarte in their orchard of Armking variety nectarines in Boulternere 66, France. The new variety was found as a mutation on a branch on an Armking tree in the Prim&#39;s orchard, in Bouleternere 66, in the parcel No. 478/Section A-- Lieu-Dit &#34;Les Maillols&#34; by the three applicants. 
     The new variety, given the varietal name Prita, was reproduced asexually by Jean-Pierre Darnaud. The reproduction was accomplished by grafting on Persica Sylvestris in 1984. These trees exhibit the same characteristics as the mother tree.

     FRUIT 
     Ripening dates: Generally ripens in early June at Perpignan, France over six years of observations, first ripening ranged from June 2 to June 15; ripens generally 5 days later, about 10 days to two weeks after &#34;Springtime&#34; peach, averaging about 12 days later. 
     Maturity when described: Hard-ripe. 
     Size: From medium to large for its season. 
     Axial diameter.--From 21/4 inches to 21/2 inches. 
     Transverse diameter in suture plane.--From 21/4 inches to 21/2 inches. 
     Transverse diameter at right angles to suture plane.--From 21/4 inches to 21/2 inches. 
     Form: Relatively uniform; globose; sometimes slightly compressed laterally. 
     Suture: Straw Yellow; Generally shallow; extending from base to apex on ventral side; slight depression beyond pistil point. 
     Ventral surface: Rounded; usually lipped throughout; lips usually unequal. 
     Stem cavity: Usually rounded; sometimes slightly elongated in suture plane, with suture showing on one side. 
     Depth.--From 1/4 inch to 3/8 inch. 
     Width.--From 3/4 inch to 1 inch. 
     Base: From rounded to truncate. 
     Apex: Generally rounded; sometimes slight conical shape to end of fruit; pistil point insignificant. 
     Stem: From medium caliper to thick; glabrous; weak adherence to stone. 
     Length.--From about 1/4 inch to 3/8 inch. 
     Skin: 
     Thickness.--From medium to thin.

     Dorsal edge.--Narrow; with shallow, narrow grove toward base; ridges on either side interrupted. 
     Color.--Between Vinaceous-Cinnamon, Plate XXIX (R) and Pinkish Cinnamon, Plate XXIX (R). 
     PLANT CHARACTERISTICS 
     The new variety of tree is of normal size, and the time of beginning of flowering is early. The flower shape is campanulate and the petal size is medium with a round petiole being present. 
     The color of the fruit is white and this is one of the characteristics of Prita which distinguishes it from its parent Armking. The stone adheres to the flesh, and the fruit matures early. 
     The new variety Prita also is differentiated from its parent Armking in the nature of its leaves which are characteristically more white on their under surface, especially the vein, than the leaves of its parent Armking. 
     In other respects the new variety Prita is similar to its parent Armking such as: 
     DISTINGUISHING TRAITS 
     (1) A vigorous tree habit, with a size, volume and chilling requirement approximately that of &#34;Armking&#34; (U.S. Plant Pat. No. 2,943), 
     (2) The production of large crops of fruit of relatively large size and attractive appearance for fruit of such a ripening season as that of the new variety; 
     (3) A fruit ripening period which, on the average, is in the ripening season of &#34;Armking&#34; nectarine (U.S. Plant Pat. No. 2,943). 
     (4) Uniform fruit size, with a rounded to truncate fruit shape; 
     (5) An attractive fruit color, with a contrast of Yellow to Yellow ground color, heavily overlaid on one side with a red coloration which becomes particularly bright at the tree-ripe stage; 
     (6) Smooth fruit skin which is characteristic of the nectarine, without pubescence; 
     (7) White fruit flesh, with only a slight trace of red in the apical area when the fruit is tree-ripe; 
     (8) A tendency for the fruit flesh to cling to the stone to a slight degree until it is fully ripe, characteristic of early-ripening peaches and nectarines; and 
     (9) A distinctive and pleasing nectarine flavor, with a good balance between sugar and acid, better than &#34;Armking.&#34; 
     The new variety Prita multiplies and reproduces faithfully by grafting. 
     Mr. Jean-Pierre Darnaud has applied for a French certificate of plant development for this new variety and was granted the number 05424 on Sep. 2, 1985.
