小麦异代换系的研究在理论和实践上都具有重要意义,在理论上可作为向小麦转移外源有用基因片段的基本材料;用于研究亲缘种属的基因定位;亲缘种属各个染色体在小麦背景下的遗传作用以及小麦亲缘种属之间的进化关系。如我国先后引进的“山前麦”,“洛夫林”10、13等系统都是1R/1B异代换系,除生产上直接利用外,还用这些材
The research on wheat alien substitution lines is of great significance both in theory and in practice, and can theoretically be used as the basic material for transferring exogenous useful gene fragments to wheat. It is used to study the gene localization of relatives, The genetic role of wheat in the context and the evolutionary relationship between wheat relatives. As China has introduced the “Piedmont wheat”, “Lovrin” 10,13 and other systems are 1R / 1B alien substitution system, in addition to the direct use of production, but also the use of these materials
