Natural allotetraploid Gossypium evolved 1 to 2 MYA from diploid A- and D-genome progenitors, most similar to the modern species G. arboreum and G. raimondii [8, 43]. The A-genome parent is the inferred cytoplasmic donor to G. hirsutum [44, 45], and thus the F1 cross was created in the same manner, with A2 as the maternal parent.
