摘  要：
Flat-nectrine peach combines with flat shape and nectarine glabrous surface, more convenient and more beautiful for consumer. Especially, as heritable pleiotropy of glabrous and saucer shape gene loci from peach, flat-nectrine peach has higher sugar, more sweet, but small size and cracked fruit are biggest problem.'Zhongyoupan 9'is an early-middle ripening flat nectarine peach. Its seed was derived from a crossing'98-4-32'with'Zhen 1-3'in 2007. The female parent'98-4-32'is an advanced seedling. The male parent'Zhen 1-3'is a good yellow flat nectarine superior line. The pollination was done in 2007. The seedling was gotten by embyro culture and was raised in greenhouse. All seedlings were planted in open field with density of 1.0 m×4.0 m at the early of May in 2008. The advanced seedling'07-7-6'was selected in 2011, then it is top-worked in Wenxian county in Henan province. Under a row spacing of 2 × 4 meters cultivating, the average yield was 20 kg for every tree in the third year and 30.0 kg in the fourth year. It has a big size, average 200 g and the biggest can reach 350 g. The fruit is covered nearly 100% red flush. The SSC is more than 15%, and flavor is good with high sugar and low acid. The flesh is yellow, texture is non-melting, cling stone. Flower is pink, showy, pollen fertile. The leave is lanceolate, leaf glands kidney-shaped. In Zhengzhou, the early blooming period is in late March. Fruit ripens in early of July and the fruit development period is about 100 days. The termination period of fallen leaves is in mid-November, and the full growth period is 260 days. Compared to'Zhongyoupan 5','Zhongyoupan 9'has better shape, larger longitudinal diameter, bigger size and10 days later ripening date. Summer and winter pruning management should balanced stronger tree vigor. Flowers thinning and fruit thinning are must be done. In general, the distance between the fruit should be greater than 25 cm, we should keep 2-3 fruits in long fruit branch, 1-2 fruit in middle fruit branch. The fruit should avoid direct sunlight. Fruit bagged is suggested toadvoid fruit cracked and get more beautiful surface. For bagged ftuit, the surface has redness in the open field and is golden yellow in greenhouse. It has good texture, fruit can be picked up until fruit ripening well in the tree. It was gotten royal license in 2018.
