There is at least one other reason that I can think of that makes commercial cloning a poor choice. (From Wikipedia)
Panama disease (or
Fusarium wilt) is a
plant disease that infects
banana plants (
Musa spp.). It is a wilting disease caused by the fungus
Fusarium oxysporum f. sp. cubense (Foc). The pathogen is resistant to
fungicides and until now, its control is limited to phytosanitary measures.
[1] Although a transgenic banana cultivar that proved resistant to Panama disease has been recently developed,
[2] it is not commercially available yet.
During the 1950s, a first outbreak of Panama disease almost wiped out the commercial
Gros Michel banana production. The Gros Michel banana was the dominant
cultivar of bananas, and Fusarium wilt inflicted enormous costs and forced producers to switch to other, disease-resistant cultivars. Currently, a new outbreak of Panama disease caused by the strain Tropical Race 4 (TR4) threatens the production of today's most popular cultivars,
Cavendish.
