* Helminthosporium sativum rated on a double-digit modified scale: the first digit indicates the height of infection, where 1 = lowest leaf; 5 = up to mid-plant; and 9 = up to flag leaf;
the second digit indicates disease severity on infected leaves, where 1 = 10 % coverage; 5 = 50 % coverage; and 9 = 90 % coverage.
** Synthetic hexaploid with the Ae. tauschii CIMMYT accession number in parenthesis and CIMMYT pedigree numbers in brackets.
*** Grain finish scale of 1 to 5, where 1 = low grain infection and 5 = severely infected.
