摘要: 2n配子在植物进化过程中起了重要作用,目前,自发、诱发2n配子已在马铃薯、苜蓿、红三叶草、越桔等作物的育种实践中应用,并分别获得了良好的效果。本文综述了关于植物2n配子的主要研究方向和近期取得的研究结果;植物自发、诱发2n配子在有性多倍化、利用种质资源、传递杂种优势、克服胚乳平衡数障碍、克服自交不亲合、马铃薯实生育种及其他领域应用的优越性和已取得的成果;国际国内通过轮回选择、2n花粉机械分离、诱导基因突变及直接诱导2n配子等方法提高2n配子利用效率的研究进展;2n配子育种的应用前景。

Abstract: The advantages,the prospects of the use of 2n gametes in plant breeding and germplasm enhancement,and the significance of unreduced gametes in plant evolution have been conf irmed. Both spantoneous andinduced 2n gametes were practicaly used in breeding programs of potato,red clove,goose berry etc. with admirableresult. The aim of this paper is to make an up- to- date review of 2n gametes in 4 subtopics. 1) Theg eneral research fields and their recent results; 2) the advances and the achivements of the use of 2n gametes in sexual polyploidization,germplasm utilization,maximizing heterozygosity,vercoming the Endosperm BalanceNumber barrier,breaking self-incompatibility,breeding for True Potato Seed and some else projects; 3) therecent studies on manipulating the efficiency of 2n gametes through recurrent selection,mechanical seperat ing 2n pollen,induced meiot ic mutant orinduction of 2n gametes; 4) the prospects of 2n gamete utilization.
