Musapedia pages on NARITA hybrids

'NARITA 6' 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 6’ is named after NARO and IITA, the institutes that jointly developed the NARITA hybrids[1].

Two crosses were performed to obtain ‘NARITA 6’. 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 6' (see Breeding strategy below).

Breeding strategy

Breeding scheme for 'NARITA 6'

‘NARITA 6’ is a secondary triploid obtained by crossing a disease-resistant tetraploid (222K-1) with an improved diploid (9128-3)[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 9128-3 (whose code used to be preceded by TMBx, for tropical Musa bananas[3]) had been obtained by crossing two diploid cultivars: ‘Tjau Lagada’ and ‘Pisang Lilin’.
