摘要：
蟠桃是桃的變種, 為我國特有資源。由于過去蟠桃品種數量有限, 產量低, 果實易爛頂裂核, 制約了蟠桃的栽培與發(fā)展。北京市農林科學院林業(yè)果樹研究所從20世紀70年代末開展了蟠桃育種工作, 其中已育成的‘早露蟠桃、‘瑞蟠4號’等品種已在生產上大面積推廣。新疆是蟠桃的原產地，如今，蟠桃在新疆、山東、河北、陜西、山西、甘肅等省區(qū)均有栽培，但從品質、色澤、口感、各種營養(yǎng)成份上比較，數新疆的蟠桃最好。石河子，伊犁等地均有栽培。開展早熟蟠桃育種研究，蟠桃胚培養(yǎng)是提高育種效率的關鍵技術。本研究針對這一領域開展工作，為應用蟠桃胚培養(yǎng)技術開展極早熟蟠桃品種選育工作打下了基礎。
Abstract: The red flat peach (from American) was chosen as female parent and Guifeihong, Zaolupan and Yingleer as male parent. Hybrids from artificial crossing were harvested at the dessert-ripe stage, and then embryos after 60d stratification on seed germination were cultured MS plant medium. The result were showed that media could promoted embryo germination and development with 6-BA 2mg/L, IBA 1mg/L and root differentiation and growth with 6-BA 1mg/L, IBA 2mg/L.
Keywords: flat peach; hybrid; embryo culture
