摘　　要：为给文冠果的良种选育提供基础材料,采用不同的标准对文冠果的种类进行了划分,并根据其可孕花比例、结实性状、种子千粒质量和历年丰产性等性状特点,对新疆维吾尔自治区木垒县和察布查尔县林场的文冠果结果大树进行了优良高产单株的筛选。结果表明：按文冠果花结构类型（雄花、长短花丝两性花、短花丝两性花）和结实特性（结实、不结实）的不同,可将文冠果树分为雄树、雌雄同株不结果树和雌雄同株结果树;在木垒县和察布查尔县林场结果大树分布区共筛选出了6株文冠果优良高产单株,其可孕花比例达30%-73%,每棵树的年产量达7.0-13.5 kg。In order to provide essential materials for selective breeding of Xanthoceras sorbifolia Bunge,according to botanic fecundity（fructiferous,fruitless） and type of flower structure（staminate flower,bisexual flower with long and short filaments,bisexual flower with short filaments）,X.sorbifolia Bunge were divided into three groups,staminiferous plant,monoecism of unfruitful plant,and monoecism of fructicative plant.Based on synthesis characters,such as proportion of fertile flowers,fruit character,thousand seeds weight,and yielding ability of the past years,and so on,six excellent high-yield and high-quality plants were selected from Mulei and Chabuchaer.For the six selected plants,the proportion of fertile flowers could reach 30%-73% and annual output could reach to 7-13.5 kg per plant.
