Abstract：Yanfen No.1 is a new ornamental peach cultivar selected from the progeny of a cross between Yanhongzaohua as the maternal parent and Zaotiantao as the paternal parent. In 2O13，the hybrid fruits were harvested and the seeds were sown that year，successfully breeding 30 seedlings.In 2015，after the seedlings flowered， excellent individual plants were selected.The initial flowering period of this individual plant is around March 3rd，14 days earlier than thematernal parent Yanhongzaohua.The peak flowering period is spectacular， with high ornamental value. Subsequently， using peach as the rootstock，grafting propagation were carried out year after year. Characteristics such as flowers，leaves and fruits were recorded，and indicators such as flower diameter，internode length and fruit size were measured. It was found that the progeny traits were stable and consistent with the maternal plant’s performance，and it was tentatively named Yanfen No.1.
