  1. For kernel, the LHRF_F3:4 segregating population derived from F2 × F252 crossing. For leaf, populations derived from Polj17 × F2 crossing [39, 44, 45], high ABA × low ABA lines [39, 44, 45] and F2 × MBS847 RILs [39, 44, 45]. Plants were submitted to water deprivation at comparable young stage in [39, 44, 45] and [39, 44, 45]. In [39, 44, 45], ABA concentration was determined in leaf samples from stressed plants irrigated with 50% normal rainfall during stem elongation and before anthesis. Gene codes are detailed in Tables 3 and 4. Genes in bold were mapped by PCR in this study (Table 4 and Additional file 2). Genes involved in kernel drying and located in the vicinity of the QTL confidence interval, are indicated in grey. ABA_embryo: [ABA] in embryo; ABA_endosperm: [ABA] in endosperm; ABAL: leaf [ABA] ABAX: xylem [ABA]; DW: kernel dry matter weight (mg/kernel); FW: kernel fresh matter weight (mg/kernel); %DW = DW/FW× 100; Slope: regression line slope of (Water/FW × 100) as a function of thermal time; RWC: relative water content; Water: kernel water content (mg/kernel); ΨL: leaf water potential.
