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效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、3A3B、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。
A1l 21 substitutions of common wheat(T aestivum L.) and their parenta1 cultivars ' Chinese Spring' (recipient) and 'Hope' (donor) were eva1uated for their relative heat tolerance as measurcd by membrane thcrmostability to determine the chromosomal locations of genes controlling this trait. Rcsults indicate that chromosomes 1A, 2A, 2B, 2D, 3A, 3B, 3D, 5D and 6B were associated with heat tolerance of cv. Hopc, while the others were not related to heat tolerance.
