  2. AD, days to anthesis; MC1, % stover moisture content; MC2, % head moisture content; BY, biomass yield (t.ha−1)
  3. GY, grain yield (t.ha−1); TW, test weight (g); GS, grain/stover ratio (%). a2.0-LOD drop support interval of the QTL; bAdditive effect: positive values of the additive effect indicate that alleles from CK60 were in the direction of increasing the trait score and vice versa; c Percentage of phenotypic variation explained by the QTL. The SNP underlined is the corresponding SNP of QTL
