摘　　要：聚合多个有效基因,不仅可以提高作物的抗性,而且可以提高作物的产量和营养品质。尤其是在抗病方面,单基因长时间反复利用容易丧失其抗病性,多基因聚合有利于拓宽抗谱,提高作物的抗性。此外,基因聚合育种与常规育种方法相结合已经成为今后育种主要方法。本研究介绍了作物基因聚合育种的主要方法、聚合基因的互作以及聚合基因在育种上的应用,对目前作物聚合育种存在的不足进行了分析,并对未来的聚合育种目标进行了展望,以期推动作物聚合育种的研究。基因聚合育种主要集中应用在大田作物上,在园艺作物上的研究应用较少,因此,需要加强对基因聚合育种的了解,促进基因聚合育种在园艺作物上的研究。Pyramiding multiple effective genes can improve not only the resistance of plants,but also the yield and nutritional quality of plants.Especially in the field of disease resistance,it is easy to lose the disease resistance of plants by repeatedly using the single gene for a long time.On the contrary,pyramiding multiple genes is beneficial to broadening the resistance spectrum and improving the resistance of plants.Furthermore,the combination of pyramiding breeding and conventional breeding methods has become the main method for breeding in the future.In this research,the primary methods of pyramiding breeding,interaction between pyramiding genes and application of pyramiding gene in breeding were reviewed.Deficiency about present plant pyramiding breeding have also been analyzed in this paper.In addition,the aims of pyramiding breeding in the future were discussed,in order to contribute to the research on the pyramiding breeding.Pyramiding breeding is mainly applied to field crops,but only a few of horticultural plants are involved in pyramiding breeding.Therefore,it is necessary to strengthen understanding of pyramiding breeding,so as to promote the research on the pyramiding breeding of horticultural plants.
