  1. Position in pcM on the LHRF_F3:4_1201 map of the segregating population. ABA_embryo: ABA in embryo (pg/DW); ABA_endosperm: ABA in endosperm (pg/DW); DW: kernel dry matter weight (mg/kernel); FW: kernel fresh matter weight (mg/kernel); %DW = DW/FWĂ— 100; Water: kernel water content (mg/kernel); Rate = (Water/FW Ă— 100)/(thermal time interval); Slope: regression line slope of (Water/FW Ă— 100) as a function of thermal time. The genomewide risk, P, (absence of any QTL in the genome) was computed by classical permutation for a given LOD score (see Methods) and reported after the LOD value: * P < 0.25, ** P < 0.10, *** P < 0.05 and **** P < 0.01. The individual significance level (risk of absence of a QTL at a specified locus, not taking in account the multiple comparisons at other loci) is 0.001 for a 2.45 LOD score.
