There are many reports describing chromosome structure, organization and evolution within goatgrasses (Aegilops spp.). Chromosome banding and fluorescence in situ hybridization techniques are main methods used to identify Aegilops Linnaeus, 1753 chromosomes. These data have essential value considering the close genetic and genomic relationship of goatgrasses with wheat (Triticumaestivum Linnaeus, 1753) and triticale (× Triticosecale Wittmack, 1899). A key question is whether those protocols are useful and effective for tracking Aegilops chromosomes or chromosome segments in genetic background of cultivated cereals. This article is a review of scientific reports describing chromosome identification methods, which were applied for development of prebreeding plant material and for transfer of desirable traits into Triticum Linnaeus, 1753 cultivated species. Moreover, this paper is a resume of the most efficient cytomolecular markers, which can be used to follow the introgression of Aegilops chromatin during the breeding process.

用于鉴定和转移埃及伊蚊的细胞学标记。染色质携带有价值的基因到小麦的栽培形式中。

有许多报道描述山羊草中的染色体结构,组织和进化(Aegilops spp。)。染色体显带和荧光原位杂交技术是用于鉴定1753年染色体Aegilops Linnaeus的主要方法。考虑到山羊草与小麦(Triticumaestivum Linnaeus,1753)和黑小麦(×Triticosecale Wittmack,1899)的密切遗传和基因组关系,这些数据具有重要价值。一个关键问题是这些协议对于在栽培谷物的遗传背景中追踪埃及伊蚊的染色体或染色体区段是否有用和有效。本文是对描述染色体鉴定方法的科学报告的综述,该方法已用于开发预育植物材料和将所需性状转移到小麦中,1753个栽培种。此外,本文是最有效的细胞分子标记的简历,可用于追踪繁殖过程中埃及伊蚊的染色质渗入。
