Aging assays were performed at two RHs (60% and 75%) and 35°C. Percentages of final germination (%FG) and of normal seedlings (%NS) were determined at the indicated days of storage. Position in centimorgans (cM) from the LR4 map are described by Vandecasteele et al. (2011). LG, linkage group; LOD, logarithm of the odds; R2, percentage of phenotypic variance explained.
