Shoot regeneration capacity of 88 Arabidopsis accessions. Means ± SEMs for the number of shoots per root explant (top axis) and the regeneration rate [i.e., the average number of explants producing at least one shoot (bottom axis)] after 14 and 21 d of SIM incubation. Each experiment was replicated three (number of shoots) or six (regeneration rate) times, with 30 explants per accession. The more recalcitrant Ga-0 (blue) and the regenerative Nok-3 (orange) accession were selected for QTL analysis.
