GENUS AND SPECIES
The variety of this invention is botanically identified as Musa acuminata×balbisiana group AAB, AA representing two genomes of M. acuminata and B representing one genome of M balbisiana.
VARIETY DENOMINATION
The variety denomination is ‘CQB 114’.
BACKGROUND OF THE INVENTION
This invention relates to a new and distinctive hybrid banana variety designated as ‘CQB 114’. The new hybrid variety was the result of a field cross performed at Fundacion Hondurena de Investigacion Agricola (FHIA) in 2005 in La Lima, Cortes, Honduras between SH-4001×Pisang Mas (both unpatented). SH-4001 is a tetraploid French plantain (AAAB) with high content of provitamin A carotenoids (pVAC) from the FHIA germplasm collection. The male parent, Pisang Mas is a naturally occurring diploid (AA). Pisang Mas produces small bunches and very sweet-flavored fingers, which are eaten fresh or used as dessert and are sweeter than the common Cavendish banana.
‘CQB 114’ was selected in 2008 from several first-generation seedlings from the cross between SH-4001×Pisang Mas. It was selected as a triploid hybrid that maintained the productivity, high content of pVAC, and black Sigatoka leaf spot disease-resistance of its SH-4001 female parental line and produced the very sweet-flavored fruit of the male parental variety Pisang Mas.
‘CQB 114’ was asexually reproduced by corms by the inventor in the Centro Experimental Demostrativo, the experimental farm of FHIA in La Lima, Cortes, Honduras. All plant and fruit characteristics run true to the original selected plant and are identical in all aspects.
BRIEF SUMMARY OF VARIETY DESCRIPTION
‘CQB 114’ is a hybrid banana variety that has high provitamin A cartenoid content, has resistance to black Sigatoka leaf spot disease, and produces-sweet-flavored fruit that can be eaten fresh or used in desserts; or eaten green when cooked.

DETAILED DESCRIPTION OF THE INVENTION
The following is a detailed botanical description of the new variety ‘CQB 114’. The description is from plants located in Limon, Costa Rica that were evaluated between 2013 and 2014. The Ratooning Index is from data collected in an experimental plot located in El Progreso, Honduras. Colors are described using Munsell Color Chart for Plant Tissues. The descriptions are in accordance with the internationally standardized “Descriptors for Banana (Musa spp.)” elaborated by IPGRI-INIBAP/CIRAD, 1996.
The ‘CQB 114’ plant and its fruit may vary slightly from the detailed descriptors shown below due to cultural practices, soil types and climatic conditions under which the variety may be grown.
