ITC code

to be confirmed

'NARITA 27' is a high-yielding and disease-resistant hybrid that is related, through its female grandparent, to a group of cooking and beer bananas called East African highland bananas (EAHB). ‘NARITA 27’ is named after NARO and IITA, the institutes that jointly developed the NARITA hybrids[1].

Two crosses were performed to obtain ‘NARITA 27’. The triploid EAHB cultivar ‘Nfuuka’ was crossed with a wild source of disease resistance to produce a tetraploid. This tetraploid was then crossed with an improved diploid to produce the triploid hybrid ‘NARITA 27’ (see Breeding strategy below).

Breeding strategy

Breeding scheme for 'NARITA 27'

‘NARITA 27’ is a secondary triploid obtained by crossing a disease-resistant tetraploid (222K-1) with an improved diploid developed by FHIA (SH3362)[2].

The tetraploid female parent 222K-1 was obtained by crossing the triploid EAHB cultivar ‘Nfuuka’ and Calcutta 4, a genebank accession of the diploid wild species Musa acuminata ssp. burmannica, which provided a copy of the so-called A genome. Calcutta 4 provided the resistance to black leaf streak.

The diploid male parent SH3362 was the product of a cross between two improved diploids: SH3217 (itself the product of a cross between two improved diploids: SH2095 and SH2766) and SH3142 (itself the product of a cross between two 'Pisang Jari Buaya' (AA)).

The parents of SH2095 were the products of a cross between 'Sinwobogi' (AA) and 'Tjau Lagada' (AA) and of a cross between Musa acuminata ssp. malaccensis and 'Guyod' (AA).

The parents of SH2766 were 'Tjau Lagada' (AA) and the product of a cross between Musa acuminata ssp. malaccensis and 'Guyod' (AA).
