远缘杂交对于作物改良具有巨大的潜力,它已被应用于植物育种实践、基因定位和染色体行为的研究.远缘杂交的历史就是逐渐增加跨越分类距离再生能力的历史,这种趋势到现在已发展到横跨禾本科的两个亚科即早熟禾亚科(Pooideae)和黍亚科(Panicoideae)之间的杂交.作为与CIMMYT合作研究玉米远缘杂交中授粉后的早期情况研究这一课题的一个部分,我们研究了Zenkteler等(1984)有关给六倍体小麦授以玉米花粉后产生了胚的一篇报告 Distant hybridization has great potential for crop improvement and has been used in plant breeding practices, gene mapping and chromosomal behavior studies. The history of distant hybridization is a history of gradual increases in the ability to reproduce across classes of distances, a trend that has now To the cross between Poaceae, the two subfamilies, Pooideae and Panicoideae, was the subject of an earlier study of pollination in maize distant hybrids in collaboration with CIMMYT We report a report by Zenkteler et al. (1984) on embryos produced after pollination of hexaploid wheat
