扁桃种质资源(germplasm resources of almond)
具有一定的遗传物质，在扁桃生产和育种上有利用价值植物的总称。扁桃在世界约有40种。原产小亚细亚、叙利亚、伊朗以至中细亚一带。人工栽培的仅为普通扁桃(Prunus communis Fritsch.)。扁桃主产国目前所用的栽培种多为杂交种。中国新疆少量扁桃栽培中包括有数十个农家品种和类型。中国的几种扁桃野生种均为灌木型。主要分布在浅山带阳坡、半阳坡和开阔谷地。喜光、耐旱、耐瘠薄土壤，能在砾土、砾质土、石壁上生长。移栽不易成活，通常用种子繁殖主要的种有：蒙古扁桃(Prunus mongolica Maxim.)、西康扁桃(P.tangutica Korsh.)、长柄扁桃(P.pedunculatus Pall.)、矮扁桃(P.tenella Rehd.)。
