Genetic variation in the tri-hybrid Allium population. a Relative mycorrhizal responsiveness (R′) as a function of total dry weight (TDW) of non-mycorrhizal (NM) plants in experiments 2006 and 2007; b Idem, for mycorrhizal (AM) plants; c Absolute mycorrhizal responsiveness (R) as a function of TDW of NM plants in 2006 and 2007; d idem for AM plants; e Average performance (AP) as a function of TDW of NM plants in 2006 and 2007; f idem for AM plants. Pearson correlations (ns: p > 0.05; *p < 0.05; **p < 0.01; ***p < 0.001)
