以中国春-Synthetic 6x染色体代换系及其亲本为材料,通过测定不同磷处理条件下的产量性状(单穗粒数、穗粒重、千粒重),对耐低磷胁迫特性的基因进行染色体定位.结果表明,低磷胁迫下,Synthetic 6x的6A、7A、1B、2B、3B、4B、5B、6B、7D染色体上可能携有促进单穗粒重的相关基因;2A、5A、6A、3B、5B、6B、7B、5D、7D染色体上可能携有促进千粒重的有关基因;6A、7A、1B、3B、2D、7D染色体上携有促进单穗粒数的相关基因.表明Synthetic 6x的6A、3B、7D染色体上可能携有与耐低磷胁迫特性有关的基因.

Wheat substitution lines between Chinese Spring and Synthetic 6x under the treatments of phosphorus deficiency stress and phosphorus normal(control)were studied to locate the gene controlling yield traits. Several yield components such as grain weight per spike,1000-grain weight and kernel number per spike were measured. The results showed that the genes promoting grain weight per spike might be located on 6A,7A,1B,2B,3B,4B,5B,6B and 7D chromosome of Synthetic 6x,and that the genes promoting 1000-grain weight might be located on 2A,5A,6A,3B,5B,6B,7B,5D and 7D chromosome, and that the genes promoting relative kernel number per spike might be located on 6A,7A,1B,3B,2D and 7D chromosome under the low-phosphorus stress. It was concluded that chromosome 6A,3B and 7D of Synthetic 6x probably carried related genes tolerating low phosphorus stress.
