aYLD total grain yield/plant(g), PW panicle weight (g), PH plant height (cm), FLW flag leaf width (cm), PL panicle length (cm).
bDesignation of the QTLs is in accordance with the rules recommended by Ref.22.
cLogarithm of the odds ratio (LOD) score of ≥ 2.5 was set as threshold for this data.
dTotal phenotypic variance (PVE%) in percentage explained by the QTL.
eAdditive effect-Negative additive effect value indicates the direction of favorable allele from donor parent, KMR-3R, that increased the trait value.
fPhenotypic variation explained by the final regression model.
gQTL hotspots on chr 3 for total grain yield/plant (g) and panicle length (cm).
