摘　　要：为给甘肃省文冠果优良品种的选育奠定基础,同时为给甘肃省生物质能源林建设提供优良繁育材料,针对甘肃省文冠果生物质能源林发展迅速而优良繁育材料非常缺乏的问题,于2010—2012年,采用群众荐优和实地调查相结合的方法,对该省庆阳、定西和白银等市的文冠果野生种群和人工种群进行了优良单株的选择研究。经过初选、复选和决选,最终选出了产量高或观赏价值高、果实品质好、抗病虫能力强的文冠果优良单株16株,其中能源利用性优良单株14株,占入选优良单株总数的87.50%,观赏性优良单株2株,占入选优良单株总数的12.50%。选出的优良单株其总体特征表现为:花色,以红色花型为主,此类单株占优良单株总数的62.50%;新梢和花轴,以红色、无毛型为主,此类单株占入选优良单株总数的93.75%;果实,以中、小果型为主,此类单株占优良单株总数的81.25%。In order to lay a foundation for selecting and breeding of improved varieties in Xanthoceras sorbifolia in Gansu Province and supply fine breeding materials for biomass energy forest construction in Gansu Province, fine individual selection of artificial population and wild population ofX. sorbifolia was conducted in 2010-2012 at Qingyang, Dingxi and Baiyin, aimed to sloving the problem of rapid development of biomass energy X. sorbifolia forest and lack of superior breeding materials, by adoping the method of combining the masses＇ recommendation and on-the-spot investigation. Through primary selection, multiple selection and decisive selection, 16 fine individuals ofX. sorbifolia were selected, and they had high yield or high ornamental value, superior fruit quality, strong pest and disease resistance. Among them, 14 individuals could be used as energy plants and 2 individuals as ornamental plants, and they accounted for 87,50% and 12.50% of selected fine individuals respectively. On the whole, morphological characteristics of selected individuals behaved as： red was of dominant flower color, accounting for 62.50% of all selected fine individuals; red glabrous twig and rachis were of the dominant type, accounting for 93.75% of all selected fine individuals; middle and small fruits were of the dominant type, accounting for 81.25% of all selected fine individuals.
