摘要: 利用全部 21个“中国春”的“Hope”染色体代换系及其亲本品种“中国春” (受体)和“Hope”(供体)对六倍体普通小麦的细胞膜热稳定性基因进行了染色体定位研究。结果表明:普通小麦品种“Hope”的1A、2A、2B、 2D、3A、3B、3D、5D和6B等9条染色体上具有耐热性基因,而其余染色体与“Hope”的耐热性无关。
Abstract:All 21 substitutions of common wheat(T.aestivum L.)and their parental cultivars“Chinese Spring”(recipient)and “Hope”(donor)were evaluated for their relative heat tolerance as measured by membrane thermostability to determine the chromosomal locations of genes controlling this trait.Results indicate that chromosomes 1A,2A,2B,2D,3A,3B,3D,5D and 6B were associated with heat tolerance of cv.Hope,while the others were not related to heat tolerance.
