^aPosition of likelihood peak (highest LOD score).
^bPeak coordinate: physical coordinate of the likelihood peak.
^cAdditive effect: A positive value means the delay of flowering time due to Tx7000 allele. A negative value means the delay of flowering time due to BTx642 allele.
^dR² (coefficient of determination): percentage of phenotypic variance explained by the QTL.
^eND: Candidate gene is not determined.
