Many of those variants are related to the Cavendish or GM, and are not resistant to existing threats. Those that are resistant, without seeds, with similar taste, often have thinner/weaker skins causing more spoilage/loss, lower shelf lives, are more expensive to harvest/store (grow in less dense groups) etc... Those corporate behemoths would love to save money by not loosing good cropland to viruses that kill their crops, but the only solution to date that doesn't end up costing more elsewhere due to the issues mentioned above is GMO's and their potential to maintain those benefits while adding resistance (or apply those traits to other varieties that are already resistant).
