USPP27419P3 - Banana plant named ‘CQB 114’ - Google Patents

Abstract

‘CQB 114’ is a hybrid banana variety that has high provitamin A cartenoid content, has resistance to black Sigatoka, and produces very sweet fruit that can be eaten fresh or used in desserts.

Description

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, Cortés, 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

‘CQB 114’ differs from its male parent Pisang Mas as follows: ‘CQB 114’ has higher productivity compared to Pisang Mas, has fingers that are twice as long as those of Pisang Mas, has fingers that are 20% thicker than those of Pisang Mas, has bunches that are 200-300% heavier than those of Pisang Mas, and has a very high content of p-Vac compared to Pisang Mas. In addition, ‘CQB 114’ is a triploid (3n) AAB whereas Pisang Mas is a diploid (2n) AA.

‘CQB 114’ differs from its female parent SH-4001 as follows: ‘CQB 114’ has higher Brix (20 vs 27) compared to SH-4001, has longer shelf live compared to SH-4001, is firmer than SH-4001, and has more fingers of smaller size compared to SH-4001. In addition, ‘CQB 114’ is a triploid (3n) AAB where as SH-4001 is a 4n AAAB.

‘CQB 114’ differs from the common Cavandish banana in its high provitamin A cartenoid content and resistance to black Sigatoka leaf spot disease.

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. Observation were made with bunches that were 90 days old, from 360-day old plants (flowering starts at 270 days).

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.
