BACKGROUND OF THE INVENTION

This invention relates to a new and distinctive hybrid banana variety named ‘HG07’. This new hybrid variety was the result of a field cross performed in La Lima Cortés, Honduras, between ‘HG’ x ‘HG’ (Both unpatented). ‘HG’ is a triploid plant (AAA) susceptible to Black Sigatoka leaf spot disease and Fusarium oxysporum race 1, belonging to the Gros Michel group. ‘HG’ is a mutant of Gros Michel used in genetic improvement to generate tetraploid mothers; varieties of the Cavendish group replaced this variety due to its susceptibility to fusariosis. In the 20^th century, it was one of the world's most commercialized fruits due to its excellent taste and yield.

‘HG07’ is a tetraploid hybrid (AAAA) created for the genetic improvement of the Gros Michel banana group. This hybrid was selected in 2018 from several first-generation seedlings from the cross between ‘HG’ x ‘HG’. It was chosen as a tetraploid hybrid maintaining the “Gros Michel” type stature and taste of its female parental line and producing bunches of 25 kilograms with fruits of the same quality as their parents. ‘HG07’ was asexually reproduced by corms in La Lima Cortes, Honduras. All plants and fruit run true to the initially selected plant and are identical in all aspects.

‘HG07’ is a selection of crosses made between plants of the “HG” variety, inheriting its flavor, cluster shape, and plant structure. The few differences between ‘HG07’ and its parents can be seen in the shape of the fruit, which is slightly smaller and has shorter fingers. Another important difference is the fertility when used as a mother; ‘HG07’ is more fertile than its ‘HG’ parents. The other characteristics are very similar between ‘HG07’ and its ‘HG’ parents.

When comparing ‘HG07’ with a commercial cultivar such as ‘Grand Naine’ or ‘Williams’, we can say that there are important characteristic differences such as: the size of the plant, which is superior in ‘HG07’; the flavor of commercial varieties is simpler than that of ‘HG07’; the commercial varieties and ‘HG07’ have equal susceptibility to diseases such as Black Sigatoka; and commercial varieties are resistant to Fusarium oxysporum f.sp. cubense Race 1, while ‘HG07’ is susceptible.

BRIEF SUMMARY OF THE INVENTION

‘HG07’ is a hybrid dessert banana variety with a tall stature, is tolerant to Black Sigatoka, and produces high-quality fruit.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed botanical description of the new variety ‘HG07’ at nine months old. The report is from plants located in La Lima, Cortés, Honduras, that were evaluated in 2023. The descriptions concord with the internationally standardized “Descriptors for Banana (Musa spp.)” elaborated by IPGRI/INIBAP/CIRAD, 1996, and The U.K.'s Royal Horticultural Society's (R.H.S.) Colour Chart, 2001. The ‘HG07’ plant and its fruit may differ slightly from the detailed descriptors shown below due to variations in cultural practices, soil types, and climatic conditions under which the variety may be cultivated.
