'Saba' is the name given in the Philippines to a cooking banana belonging to the Saba subgroup. Its classification at the genome group level has been disputed ever since it was suggested to be a triploid derived from crosses between Musa balbisiana only[1]. Whereas some molecular analyses seem to support a BBB genome group[2][3][4], morphological traits characteristic of Musa acuminata, such as curly bracts, place it among the ABB. On the other hand, if backcrossing occured[5], it is possible that backcrosses with M. balbisiana might have led to the substitution of M. acuminata genes by M. balbisiana ones, leaving only remnants of the original M. acuminata genome.

'Saba' is especially popular in the Philippines, where the male bud is also eaten as a vegetable.

Local names

'Pisang Kepok' (Indonesia), 'Pisang Abu Nipah' (Malaysia), 'Saba' (Philippines), 'Kluai Hin' (Thailand)[6][7]

Reaction to diseases and pests

In the Philippines, where the TR4 strain of the Fusarium fungus is present, Saba (Cardava) did not show symptoms of Fusarium wilt in field trials[8].
