Note: Chr, Chromosome. LOD, logarithm of odds. Add, the additive effect of each QTL. R², Goodness of fit, represent the phenotypic variance explained by each QTL. ^a, the resistance effect of QTL come from Jin23B. 11RT and 12RT, leaf blast resistance at tillering stage in 2011 and 2012. 11RH and 12RH, leaf blast resistance at heading stage in 2011 and 2012. 11RN and 12RN, neck blast resistance at maturation stage in 2011 and 2012
