摘要: A population of 114 recombinant inbred lines (RILs), derived from the cross Opata85 x W7984, was used to genetically analyze the response of wheat to salt stress. This analysis resulted in the identification of 47 QTL mapping to all wheat chromosomes except 1B, 1D, 4B, 5D and 7D. Of these QTL, 10 were effective during the germination stage, and 37 at the seedling stage. Many of the traits related to salt tolerance mapped to common chromosome intervals, such as Xglk683-Xcdo460 on chromosome 3A, Xfbb168-Xbcd147 on chromosome 3B, Xcdo1081-Xfbb226 on chromosome 4DL and Xpsr106-Xfbb283 on chromosome 6DL. QTL located in the interval Xcdo1081-Xfbb226 (chromosome 4DL) were effective during the germination stage, whereas those in the interval Xfbb231.1-Xmwg916 (chromosome 6DL) were relevant to the seedling stage. The QTL in the intervals Xglk683-Xcdo460 (chromosome 3AS) and Xfbb168-Xbcd147 (chromosome 3BL) were effective at both the germination and seedling stages.
