小麦×玉米远缘杂交诱导小麦双单倍体的研究及育种应用进展（英文）

Research and Breeding Application Progress of the Technique of Producing Double Haploid of Wheat by Wide Hybridization between Wheat and Maize

小麦×玉米远缘杂交诱导小麦双单倍体技术具有诱导效果较好、诱导周期短、操作简便等特点,是目前诱导产生小麦单倍体效率最高的途径之一,极具育种应用潜力。文章主要综述了小麦×玉米远缘杂交诱导小麦双单倍体技术的原理与生产过程;影响该技术的三个关键指标即成胚率、成苗率与加倍成功率近年来的研究情况;该技术在小麦育种、遗传研究以及种质创新方面的应用情况。最后介绍了本项目组在该技术上取得的成绩,并论述了该技术进一步完善和发展的方向。

The technique of producing doublehaploid of wheat by distant hybridization between wheat and maize has characterized with better inducing effect, shorter in- ducing period, easy operation, and so on. At present, it is the most efficient and has great potential of application in breeding of wheat. This article reviewed princi- ple and production process of the technique, research situation of the three key in- dicators of the technology（embryo rate, seedling rate and success rate of doubling）in recent years, and application of the technology in breeding, genetics, germplasm improvement of wheat. At last, both the achievements and the direction of further improvement and development of the technology in our program were discussed.
