[Localization of genes for partial resistance to Puccinia hordei at the seedling stage in barley by using AFLP markers] [In Process Citation]
A total of four unambiguous quantitative resistance loci (QRLs) controlling latency periods in partially resistant barley against leaf rust were detected by means of AFLP linkage mapping markers and Map QTL V3.0 software, which were located on chromosome 1,2,6,7 at 79cM, 186cM, 58cM and 117cM oriented with the short arms at the top, respectively. The QRL on chromosome 7 was effective to isolate 24, but not to isolate 121 of Puccinia hordei. The merits and demerits of interval mapping (IM) and composite interval mapping (CIM) was discussed and it is advocated to declare a QTL when detected simultaneously by both methods in the paper.
