aChromosome the QTL is located on.
bThe underlined marker is closer to the QTL.
cPosition (cM) denotes the genetic distance in centiMorgan between the QTL and the first marker on the relevant chromosome.
dAdditive effect, a negative value indicates that the Zhenshan 97 allele increases phenotypic score.
ePhenotypic variation explained by an additive effect.
fAdditive by environment interaction effect, e1 and e2 represent low P in 2008 and 2009, e3 and e4 represent normal P in 2008 and 2009, respectively.
gPhenotypic variation explained by an additive by environment interaction.
hThe individual environment in which a QTL for the identical trait was detected by individual environment analysis and located in the same or neighboring region listed in the fourth column.
* and **Indicate significance at P = 0.05 and P = 0.01, respectively.
