"Distinctive cooking banana having in common a French-bunch type
and a tall pseudostem

The most relevant feature of this subdivision of the cooking banana
subgroup is that during their natural hybridization process the A genome
was transferred from the Papuan M. acuminata spp. banksii
rather than from the Asian M. acuminata (Lebot et al., 1993). Clones
under this subdivision produce fruits with organoleptic qualities similar
to those of the genuine cooking bananas. There are two Lacknau
clones in the collection, PI 23472 and PI 23479, that were originally
classified in the AAB or true plantain group (Valmayor et al., 1981), but
were later reclassified as distinctive cooking bananas (Lebot et al.,
1993; 1994). These were introduced from SIATSA, Honduras. Their
pseudostem is green. The comparison between clones demonstrated
that introduction PI 23472 developed a significantly thicker pseudostem,
required substantially more days for fruit filling, and produced
significantly heavier fruits (Table 2). There was no significant difference
between the two clones for the other plant, bunch and individual
fruit traits studied. The information obtained was not enough to maintain
a separate clonal identity. However, PI 23472 and other Lacknau
clones have been reported to possess field resistance to the corm weevil
(Cosmopolites sordidus Germar) (Irizarry et al., 1988). Clone PI 23479
has not been evaluated for this attribute. Until this evaluation is performed,
these clones should be maintained as separate entities."
