Native to China, peaches [Prunus persica (L.) Batsch] have a long cultivation history, rich germplasm resources, and various resource types (Li and Wang 2020). Peaches have an attractive appearance, unique flavor, and pronounced nutritional value, making them an important summer fruit market product (Clark and Sandefur 2013; Ognjanov et al. 2018). The flat peach is a cultivar of common peach; the shape of its fruit is flat and unique, and the fruit is famous for being juicy and delicious. The flat peach has a long history of cultivation in China, but it is mostly limited to small-scale cultivation in certain areas, such as Jiangsu and Zhejiang, which is not a strategy typically used for flat peaches across the country as a whole. The main issues with flat peach varieties are as follows: 1) the top of the fruit is not closed well, 2) the small ones have spots, and 3) the large ones are fragmented. Some cultivars exhibit the phenomenon of cracking, which forms a large hole, resulting in a loss in value. Compared with common peaches, the flat nectarine is larger and has an uneven surface, a thinner pulp, and a lower yield (Rawandoozi et al. 2021).
‘Zhongyoupanweimei’ is a newly selected, small, mid-maturing flat nectarine cultivar with a high edible rate suitable for fresh consumption. The fruit matures in mid-July in Zhengzhou and the fruit development period is ∼105 d. The chilling requirement is ∼500 to 650 h in Zhengzhou. The fruit are flat and have a pleasant golden-yellow peel with a rosy red blush on the sunny side. The flavor is sweet with a strong aroma, and the soluble solid content is 15.0% to 16.8%. The average fruit weight of ‘Zhongyoupanweimei’ is 80 to 130 g and the maximum fruit weight is 160 g.
