ABSTRACT:

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED
This triploid plant has both
Musa acuminata
and
Musa balbisiana
in its pedigree. This triploid hybrid is the product of an inter-specific cross between an improved hybrid tetraploid (AABB) type Bluggoe and an improved diploid (AA) of
Musa acuminata.
Its Latin name is
Musa acuminata×balbisiana
group AAB. AA representing two genomes of
M. acuminata
and B representing one genome of
M. balbisiana.
VARIETY DENOMINATION
‘FHIA-25’.
BACKGROUND OF THE INVENTION
This new variety was developed at the Fundación Hondureña de Investigación Agrícola (FHIA) in La Lima, Honduras from a cross made in 1995. It was selected in 1997 from several first-generation seedlings from the cross SH-3648×SH-3142 (both unpatented and both developed from accessions and breeding lines which are unpatented and are in the FHIA germplasm collection). SH-3648, which was developed by inventor, is a dwarf, bred tetraploid that is resistant to the black Sigatoka leaf spot disease. The pedigree of SH-3648 is II-408 and I-63→SH-2952×SH-2741→SH-3386×SH-3362→SH-3648. The two original II-408 and I-63 parental lines are the ‘Gaddatu’ (ABB) triploid clone from the Philippines and a
Musa balbisiana
(BB) diploid clone of unknown origin that was collected in Costa Rica, respectively. SH-2741 is a dwarf, bred diploid which was derived from AVP-45×AVP-23→SH-90×II-334→SH-2518×II-158→SH-2741. The AVP-45, AVP-23, II-334 and II-158 parental lines are a wild
Musa acuminata
subsp.
zebrina
diploid accession from Java, a ‘Robusta’ Cavendish triploid clone that was collected in Jamaica, a wild
Musa acuminata
subsp.
siamea
diploid from Malaysia, and a parthenocarpic
Musa acuminata
subsp.
errans
diploid from North Borneo, respectively. The SH-3362 diploid parental line of SH-3648 was selected from a segregating population derived from SH-3142×SH-3217. The SH-3142 diploid, which was developed by inventor and is the female parent of SH-3362 and the male parent of ‘FHIA-25’, was derived by crossing the SH-1734 bred diploid onto the ‘Pisang Jari Buaya’ natural diploid that was collected from Papua New Guinea. The diploids which are in the pedigree of SH-1734 are the ‘Lidi’ and ‘Sinwobogi’ parthenocarpic clones and a
Musa acuminata
subsp.
errans
wild type that were collected in Sumatra, Irian Jaya, and the Philippines, respectively. The SH-3217 parent of SH-3362 is a complex bred diploid, which has in its pedigree the parthenocarpic ‘Guyod’, ‘Tjau Lagada’, and ‘Sinwobogi’ natural diploids and a wild
Musa acuminata
subsp.
malaccensis
accession from the Philippines, Java, Irian Jaya, and Malaysia, respectively. ‘FHIA-25’ was selected as a hybrid triploid that maintained the dwarf plant stature and black Sigatoka resistance of its SH-3648 tetraploid parental line, but differs from SH-3648 in that it does not produce pollen. This absence of pollen results in seedless fruit, as compared to the seedy fruit of SH-3648, and this characteristic of ‘FHIA-25’ permits it to be cultivated as a commercial variety without concerns about seediness. ‘FHIA-25’ is also readily distinguished from SH-3648 by its rounded fruit shape, which closely resembles that of the reference Cavendish export banana, as compared to a more angular fruit shape for SH-3648.
This new cooking banana plant was asexually reproduced by corms as performed by inventor in the experimental farm of FHIA in La Lima, Cortés, Honduras and shows that all plant and fruit characteristics run true to the original selected plant and are identical in all respects.
BRIEF SUMMARY OF THE INVENTION
This new and distinct variety of cooking banana is a vigorous dwarf plant that produces large bunches of fruit. It is highly resistant to the black Sigatoka leaf spot disease, which is the most destructive and most costly disease of bananas and plantains worldwide. Interest in this new variety is that it is the first dwarf cooking banana that is highly resistant to black Sigatoka and has excellent cooking qualities as green fruit. This combination of exceptional plant and fruit characteristics make it a candidate for cultivation as a green cooking banana in areas where black Sigatoka has severely reduced the yields of the natural banana and plantain varieties that have traditionally been cultivated for production of green fruit for cooking.
