Quantitative trait loci (QTL) were identified by nested association mapping of GLS resistance. Model selection results are given in relation to the co-localizing QTL associated with previously published studies. p<0.0001, Chr = Chromosome
CI = Confidence Interval
DTA = Blacksburg (Whitethorne Farms)-specific days to anthesis
Southern Leaf Blight (SLB) QTL Source: [46]
Northern Leaf Blight (NLB) QTL Source: [40]
Asterisks indicate better resolved QTL
double asterisks denote QTL reported here for the first time
+,- indicates significant positive, negative association of allelic effects, respectively.
