摘　　要：观赏植物种类繁多,在这些植物的育种、销售及栽培过程中,与植物病害相关的各种病原物也被广泛传播。因此,培育抗病品种一直是园艺育种工作者的重要目标性状之一。在粮食作物中,抗病育种方面已经投入了很大的人力物力,新的生物技术不断被用于作物新品种的培育。但对于观赏植物而言,这些新技术应用范围还极为有限。本综述对园艺植物抗病育种现状进行了总结,并对育种前景进行了预测。There are many kinds of horticultu ral ornamental plants. During the breeding, marketing and cultivation, various pathogens associated with these plant diseases are also widely spread. Therefore, breeding resistant varieties has always been one of the important target traits of horticultural breeders. In food crops, great efforts have been invested in disease resistance breeding. New biotechnologies are constantly being used to breed new crop varieties. But for ornamental plants, these new technologies are still extremely limited in scope. In this paper, the breeding situation of horticultural plants was summarized, and the prospects of horticultural plant breeding were predicted.
