↵F1-a Seedling survival was scored as the emergence of the first trifoliate.
↵F1-b Seed/pod and seed wt were scored individually on >120 randomly selected pod for each EMS treatment.
↵F1-c The frequency of arrested embryos was assessed in four groups of =30 seed pod each. Data are expressed both as the percentage of seed pod containing at least one arrested embryo and as the percentage of total seed analyzed (in parentheses).
↵F1-d nd, Values not determined due the absence of fertile individuals.
