(10) Due to chemical development, processing and printing, the leaves and fruit depicted in these photographs may or may not be accurate when compared to the actual botanical specimen.
DETAILED BOTANICAL DESCRIPTION
(11) The tree, flowers, and fruit may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruits by NSRED15265 is high, due to fruit very long shelf life without alteration after harvesting.
(12) Trees are medium vigorous and large stature half-standing in a semi-flared to semi-upright out aspect. The anthocyanic coloration of flowering shoot is present excluding brushwood side away from sun. The time of beginning of flowering is considered medium; the flowering usually begins at the end of February or early in March. The type of flower is showy (rosette) with medium petal size. Petals are colored in medium pink. Leaf glands are present and reniform. The fruit flesh is a dark pink red, also named blood red. The fruit skin is colored in purple red color. The stone is considered clingstone, more or less adherent depending on the fruit maturity. Fruit taste is semi-sweet, very aromatic and with a high level of sugars.
(13) Compared to NECTARCRISP white nectarine tree (U.S. Plant Pat. No. 19,384), which is the seed parent of NSRED15265, the new variety shows a surprising bright blood pink red flesh color whereas the fruits of NECTARCRISP present a white colored flesh.
(14) The ripening time of the new variety NSRED15265 is considered medium. The first fruits usually ripen early in July, sometimes at the middle of July, whereas the fruits of the variety NECTARCRISP ripen late during the season, namely early in September to mid-September depending on the years.
(15) Compared to NECTATOP yellow nectarine tree (U.S. Plant Pat. No. 21,141), which is the pollen parent of NSRED15265, the new variety shows a surprising bright blood pink red flesh color whereas the fruits of NECTATOP present a yellow colored flesh.
(16) The ripening time of the new variety NSRED15265 is considered medium, as it ripens generally early in July, sometimes at the middle of July, whereas the fruits of the variety NECTATOP ripen late during the season, namely mid-August depending on the years.
(17) Compared to NSRED15270 red-fleshed nectarine (U.S. Plant patent application Ser. No. 16/350,466 filed on Nov. 20, 2018), the ripening time of the new variety NSRED15265 is considered earlier than those of NSRED15270, as it ripens generally 2 weeks earlier. The fruits of the new variety NSRED15265 are rounder than those of NSRED15270 whose fruit are considered round and triangular. The fruits of NSRED15270 seem to be bigger and heavier than NSRED15265 fruit.
DETAILED DESCRIPTION
(18) Referring more specifically to the pomological details of this new and distinct variety of red nectarine tree, the following was observed on trees in their fourth growing season (third year of production) for trees, leaves and fruits and on trees in their third growing season (second year of production) for the flowers, under the ecological conditions prevailing at the orchards located near the town of Elne, Pyrnes-Orientales departement, France. All observations have been done on rootstock cultivars. Used rootstocks were INRA GF677 trees. All major color code designations are by reference to The R.H.S. (Royal Horticultural Society) Color Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain. Tree: Size.. Generally.Considered large. The tree size the first year was approximately 250 cm. The tree was pruned during each following dormant season to a height of approximately 250 cm. Current season shoots growth could reach 60 to 80 cm. The tree size from the second year (second and next years) reached a final height of 310 to 330 cm including current season shoots length. The tree size is consistently reduced to 250 cm the next years. Spread.Approximately 100 cm with a cylindrical shape. The whole orchard was oriented to a central leader organization, with tree lines spaced of 4.0 meters and trees spaced of 1.0 meter in a same tree line. As a result, tree spread was about 100 cm and the orchard contained 2500 trees by hectare. Vigor.Considered medium vigorous. Productivity.The productivity is considered very good and regular, every year. Fruit set is spaced by thinning to develop the remaining fruit into the desired market sized fruit. The number of the fruit set varies with the prevailing climatic conditions and cultural practices employed during the bloom period and is therefore not distinctive of the present variety. Bearer.Very regular. The fruit distribution is considered homogenous on mixed branches and spurs having more than 1 year. Thinning of 1 fruit out of 3 was necessary for the tree valorisation. Thinning was necessary every year during the years of observation. Form.The NSRED15265 variety has naturally a semi-flared to semi-upright shape. Density.Considered dense.

Use.The subject variety NSRED15265 is considered to be a nectarine tree having a medium season of fruit maturity, and which produces fruits that are considered firm, attractively colored with a dark purple red. The high content of antioxidant in the red flesh convert fruits in a very healthy product. Fruits have a semi-sweet taste and are excellent for uncooked consumption, crunchy or melting when at full maturity. Fruits have excellent gustative qualities. Due to their flesh quality, firmness and density, they can also be commercialized as 4.sup.th range product (packed fruit or fruit in bags for example). And they are also useful for both local and very long distance shipping. Keeping quality.Remarkable. Fruit have a slow maturation and a long shelf life both on the tree after growth completion and after harvesting without alteration. After growth completion, fruits are preserved more than one week. After harvest, fruits are well preserved more than 4 weeks at 2.0 degree Celsius. Shipping quality.Considered very good. The fruit of the new red blood nectarine variety showed minimal bruising of the flesh or skin damage after being subjected to normal harvesting and packing procedures. Its resistance to handling during harvest and packing and its long shelf life without alteration after harvest easily permit 3 to 4 weeks-shipping at 2 degrees Celsius. Resistance to insects and disease.No particular susceptibilities were noted. The present variety is not very sensitive to powdery mildew, or conservation diseases and decay due to its thick and strong skin.
(19) Although the new variety of nectarine tree possesses the described characteristics when grown under the ecological conditions prevailing near Elne, Pyrnes-Orientales departement, France, it should be understood that variations of the usual magnitude and characteristics incident to changes in growing conditions, fertilization, pruning, pest control and horticultural management are to be expected.
