中文摘要：
植物体的杂交在过去的 35 年稳定地进行了。许多混合植物从不同种系发生的种类的熔化联合被产生了，其中一些在庄稼繁殖被利用了，编程序。在他们之中，因为它的重要性，不对称的混血儿，通常包含很少的相异的染色体，在庄稼改进收到了更多的注意。然而，很少研究很长时间处理了体的混血儿的染色体的遗传，它限制了这条途径的进步。在上最近十年与“在 situ 杂交(ISH ) ”的一个有效细胞遗传学的工具的发展一起，有不同的草或谷物的普通小麦(Triticum aestivum L.) 的不对称的熔化极大地被开发了。遗传，染色体，功能的基因和不对称的混血儿服从于系统的调查使用基因克隆的小麦的农业特点，在 situ 杂交(GISH ) 的 genomic 和分子的制造者。未来目标是充分阐明在改进农学的特点，基因和内在的分子的机制之中的功能的关系，和体的基因渗入线的染色体动力学。这将在庄稼植物的分子的改进经由体的杂交和这些材料的应用程序加速精英细菌原生质的发展。
英文摘要：
Plant somatic hybridization has progressed steadily over the past 35 years. Many hybrid plants have been generated from fusion combinations of different phylogenetic species, some of which have been utilized in crop breeding programs. Among them, asymmetric hybrid, which usually contains a fraction of alien genome, has received more attention because of its importance in crop improvement. However, few studies have dealt with the heredity of the genome of somatic hybrid for a long time, which has limited the progress of this approach. Over recent ten years, along with the development of an effective cytogenetical tool ＂in situ hybridization （ISH）＂, asymmetric fusion of common wheat （Triticum aestivum L.） with different grasses or cereals has been greatly developed. Genetics, genomes, functional genes and agricultt, ral traits of wheat asymmetric hybrids have been subject to systematic investigations using gene cloning, genomic in situ hybridization （GISH） and molecular makers. The future goal is to fully elucidate the functional relationships among improved agronomic traits, the genes and underlying molecular mechanisms, and the genome dynamics of somatic introgression lines. This will accelerate the development of elite germplasms via somatic hybridization and the application of these materials in the molecular improvement of crop plants.
