Abstract: ‘Heishi No.1’is an excellent early-season table persimmon with black appearance. The cultivar was selected from natural persimmon germplasm resources, the variation maternal plant was discovered in Taihang mountain in 2000. It was initially selected from‘Taihei-1’for its beautiful appeareance,good flavor, high-productivity and strong resistance. After 8 years production testing from 2007 to 2014 in persimmon planting region including Luoyang, Puyang, Kaifeng, Sanmenxia and Xuchang in Henan province, and regional adaptability testing from 2010 to 2014 in Shandong, Shanxi, Anhui and Zhejiang province. We found that the genetic characteristics remained relatively stable, it was finally selected in December 2015 in Henan(No. Henan S-SV-DK-003-2015). Fruit of‘Heishi No.1’is mainly obround, crisp texture, has full deep black shiny color, with white fruit powder on the surface, and aurantiacus flesh color.Flesh is exquisite, fiber, sweet flavor. Its average fruit weight is 126.56 g, maximum fruit weight is 232.38 g, and seedless in most fruits. The content of soluble solid is 20% to 23%, the content of total sugar is19.46%, the content of total acid is 0.08%, the content of vitamin C is 406 mg·kg-1, the content of tannic is0.56%. Fruit quality is very excellent. This cultivar is vigorous with conicalness crown and semi-open tree gesture. Young branches are slightly curved, dull grey-green color. Leaves are deep green and lanceolate,18.7 cm long, 10.1 cm wide, with 1.8 cm petiles. Flowers are all female with small aorolla and light black petals.‘Heishi No.1’is a parthenocarpic, does not need pollinizer.‘Heishi No.1’begins spouting at end of March and flowering in early may. The fruit development period is about 130-140 d, and ripens at theend of September in Zhengzhou area, Henan province. The row and column spaces are 2-3 m×3-5 m. The type crown using free spindle, crown height is controlled in 3.5 m or so. Training good tree shape is important in yang tree stage. The tree could control tree size and maintain tree vigor by pruning includes pinching, bending and cutting back in full fruit period. The cultivar can flower and bear fruits after two years planting, reach high yield 48 720 kg·hm-2in the fifth year. The adult tree could control reasonable load, to ensure high and stable yield. Under normal circumstances, The adult tree must set production limits for 37 500kg·hm-2, leaving one fruit for each 8-10 cm. Fruits have long storage-life and high tolerance to storage and transportation. Cold storage life is 3-4 months and shelf life is over 30 days. It is resistant to drought, cold,and leanness. Resistance is strong, plant diseases and insect pests is relatively small, especially resistance to anthracnose and angle of spot, etc. Plain and hilly areas are both suitable in Henan, Hebei, Shandong,Shanxi, Anhui, Hubei, Jiangsu, Zhejiang and the areas of persimmon distribution.
