Fuyang (P.avium L.) is a new mild-late-maturing sweet cherry. The seeding was derived from a cross between ‘HeiZhenzhu’ and ‘Summit+Van’ in 2003 at Yantai Academy of Agricultural Sciences experimental field. The obtained hybrids were sowed in the spring of 2004, and the hybrid seedlings were planted in the Zhifu District of Yantai Academy of Agricultural Sciences in the spring of 2005, and started to bear fruit in 2008. The cross of No. 03-5-8 showed large fruit type, purple-black skin, and strong productivity, and was finally selected as the superior line. In the summer of 2010, we used Daqingye as the rootstock for grafting propagation and expanding test planting. After continuous observation and testing, the traits are stable and excellent. In February 2017, it passed the validation of Shandong Province Forest Tree Variety Validation Committee. The tree posture of Fuyang is moderate and open. The 6-year-old tree height is 3.4 m. The crown diameter is 4.1 m×4.2 m. Perennial branches are grayish white, and 1-year-old branches are grayish brown. Leaves are long spindle-shaped, light green. The middle leaf of the developed branch is 15.41 cm in length, 7.37 cm in width, and 3.25 cm in petiole length. The leaf margin is compound, shallow and blunt. The nectary is kidney-shaped, dark red, oblique or
opposite. Fuyang has strong tree vigor, stronger and more vigorous growth than Van. The trees in the full fruit period are mainly short fruit branches and bouquet fruit branches, accompanied by axillary flower buds. It started to bear fruit in the 3rd year after planting, and the natural fruiting rate was as high as 56.1%. Using the spindle shaped branching, it started to bear fruit in the 3rd year after planting, and the yield of the 4-year old tree was 268 kg per 667 m2, that of the 5-year old tree was 436.2 kg per 667 m2, and the yield of 6-year-old trees was 763 kg per 667 m2, which was high and stable. The fruit is heart-shaped, with purple black and shiny peel, dark red pulp and juice. The average single fruit weight of 9.7 g, and the pedicel is medium-short, with a length of 3.45 cm. Soluble solids content was 18.7%, total sugar content was 11.62%, total acid content was 0.61%, the edible rate of fruit is 94.6%. The fruit development period is about 55 d and it matures at the early June in Yantai. The germination rate is 98.2%, branching ability is high. The full-flowering is around April 18. No special disease of Fuyang was found in cultivation. It is resistant to storage and transportation, early fruiting, high yield, and excellent comprehensive traits. It is suitable for planting in sweet cherry suitable planting areas such as Shandong Province. Orchard should choose sandy loam soil which is flat and has ability of moisture and fertilizer retention; spacing in the rows and spacing between rows are 2~2.5 m×4 m, the configuration of pollinizer is Sparkle, Summit, Van et. al; using a slender spindle-shaped pruning, and controlling the strength of the tree to prevent overgrowth.
