^*A sub-species of G. hirsutum.

^#Only betasatellite deletion mutants lacking the βC1 gene were identified.

^@Species are indicated as either cultivated (C) or wild (W).

^$Symptoms are indicated as non-symptomatic (NS), mild (M), moderately severe (MS), severe (S) and very severe (VS).

⁺Octaploid G. hirsutum is non-cultivated, and is maintained for research purposes.
