All populations are native to Iran. (1) ploidy; (2) chromosome number; (3) genome size in pg; Petunia hybrida ‘PxPC6’ (2C = 2.85 pg), (*) Pisum sativum ‘Express Long’ (2C = 8.37 pg), and (**) Triticum aestivum ‘Chinese Spring’ (2C = 30.9 pg) were used as internal standards; (4) genome size in Mbp (1 pg = 978 Mbp); (5) standard deviation; (6) monoploid genome size; (7) half peak coefficient of variation for each population; (8) most commonly found number of CMA+ bands, together with the most usual position found for them (I = interstitial, t = terminal or subterminal, c = centromeric or pericentromeric); in brackets, other numbers of CMA+ bands found; (9) most commonly found number of rDNA sites; in brackets other numbers of rDNA sites found (position of rDNA sites is always terminal or subterminal). AThe expected number for a pentaploid would be 2n = 45 but there is an already described hypoaneuploidy for this taxon, sometimes presenting a B chromosome (2n = 44 + 1B, [105]); Btwo to three B-chromosomes occasionally found
