AAA group) developed as a cultivar of banana naturally resistant to Black and Yellow Sigatoka fungi (Mycosphaerella fijiensis and Mycosphaerella musicola respectively) in an attempt to replace the highly susceptible Cavendish banana.
[1] The FB920 cultivar was developed by the Centre de coopération internationale en recherche agronomique pour le développement under the code MU-920.
[5] With much of this production being of the Musa AAA group, there is high potential for the spread of FB920 pending appropriate local growing conditions.
[5] The design of the FB920 synthetic hybrid cultivar provides for natural resistances to a number of highly destructive pests and diseases.
[6] Black sigatoka is a fungal leaf spot disease that is considered one of the most devastating blights affecting contemporary banana cultivation.
[1] Studies have found that burrowing nematodes have a much lower propensity to propagate in FB920 samples, providing evidence of the cultivar's claimed resistance.
[12] It has also been found that FB920's fungi and nematode resistances are effective enough to warrant reductions of or terminations in fungicide and nematicide application on banana farms.
Issues with GMO acceptance rates have been identified by a Ugandan study, suggesting that other cultures may also be averse to converting their local crops to the FB920 cultivar despite the observed advantages.
[14] Without more information published about the specifics of the FB920 cultivar's optimal growing conditions and local attitudes towards technological innovation, adoption constraints, while most certainly present, are difficult to identify.
