英文摘要	Polyploidization is an important driving force for plant evolution and an effective way to breed new cultivars. Polyploid cultivars are welcome because of their larger and higher quality fruits. Chinese jujube (Ziziphus jujuba Mill.) is the most important cultivated fruit species of family Rhamnaceae. It has been introduced to nearly 50 countries and is becoming popular in arid regions taking the advantages of nutritious fruit and strong tolerance to drought, barren and salty soil. Since the cross breeding of jujube is very difficult, polyploid breeding becomes more important for jujube. In this paper, we briefly summarized the history of jujube artificial autopolyploid-ization, and systematically described the four approaches of autopolyploid induction developed in jujube, i.e., in vitro apical/lateral bud induction, in vivo apical bud induction, in vitro callus induction, and in vivo polyploidy induction via callus (IPIC), in terms of methods, effects and advantages/disadvantages. IPIC is a novel bud regeneration way and a brand-new method for autopolyploid induction, which well integrates the advantages of other three approaches and overcomes most of their shortages including serious ploidy-chimera formation and complexity of tissue culture. Using this novel approach, homogenous polyploid jujube can be obtained directly and could blossom and even set fruit in the current year, shortening the breeding cycle by more than 3 years. This article also illustrated the morphological, agronomical, cytological, nutritional and physiological characteristics of jujube tetraploids, the rapid identification procedures for polyploidy, as well as the created polyploid germ-plasms and varieties of jujube. In addition, the existing problems and challenges of artificial autopolyploidization in jujube were analyzed, the scientific utilization of jujube autopolyploidy and future research priorities of jujube polyploidization were prospected. This review aims to provide references for jujube polyploid breeding and plant artificial polyploidization research.
