Pedigree
AA x AAAA

FLHORBAN 920 is a AAA dessert banana bred by CIRAD to be resistant to Mycosphaerella fijiensis and Mycosphaerella musicola. It is also slightly tolerant to Radopholus similis and resistant to Pratylenchus coffeae. Its shelf life is too short for the export market, but other features might appeal to domestic producers.

The code of the hybrid in the CIRAD collection is CIRAD MU-920. It is available from the ITC, where its accession code is ITC1585.

Breeding strategy

FLHORBAN 920 was produced by crossing an AA cultivar with a tetraploid (AAAA). The tetraploid parent was produced by doubling the genome of a AA cultivar using colchicine (a natural substance used to induce polyploidy in plant cells).

Morphological and agronomic characteristics

FLHORBAN 920 is taller than the Cavendish cultivar Grande Naine, but is slender and its bunch smaller. Nevertheless, the annual yield may be similar or higher as a result of the short interval between harvests (about 4 months). The hybrid is characterized by a high number of small fruits, whose skin is thinner than those of Grande Naine. A panel of consumers appreciated its sweet and fruity taste. It was bred for the export market, but its shelf life and consumption life are too short.

Host reaction to pests and diseases

FLHORBAN 920 is resistant to M. fijiensis and M. musicola, the causal agents of black leaf streak and Sigatoka leaf spot respectively.

It has not been evaluated for its reaction against Fusarium oxysporum f. sp. cubense.

It is somewhat less susceptible to the nematode R. similis than Cavendish cultivars and tolerant to P. coffeae.

Recommendations for cultivation

Unlike Grande Naine, FLHORBAN 920 can be cultivated in double rows to increase yield.
