Identification of candidate genes, regions and markers for pre-harvest sprouting resistance in wheat (Triticum aestivum L.)

Table 2 Results of Multiple Interval Mapping (MIM): four QTL for PHS traits ( GI, SI, FN ) identified on chromosomes 3B, 4A, 7B.1 and 7D.2 in a DH population of RL4452/‘AC Domain’ replicated in multi-year environments (Glenlea and Winnipeg in Manitoba; Swift Current in Saskatchewan)
