USPP24315P2 - Musa plant named ‘MeKong Giant’ - Google Patents

Abstract

A new cultivar of Musa plant named ‘MeKong Giant’, that is characterized by its large green leaves with red coloration on the lower surface of the young leaves, its very fast growth habit and large stature, its good cold hardiness, its thick trunks that are streaked with dark pink to dark maroon with age, and its large underground rhizomes with new growth that returns quickly from winter dormancy.

Description

Botanical classification: Musa intinerans var. xishuangbannaens.

Cultivar designation: ‘MeKong Giant’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Musa intinerans var. xishuangbannaens known as ‘MeKong Giant’, and is hereinafter referred to as ‘MeKong Giant’. ‘MeKong Giant’ is a new cultivar of hardy banana grown for landscape use.

The Inventor selected the new cultivar, ‘MeKong Giant’, as a single unique plant in a seedbed at his nursery in Louisville, Ky. in 1993. The seedbed had been planted with 500 seeds collected from an unnamed plant of Musa intinerans var. xishuangbannaens. The male parent is unknown.

Asexual reproduction of the new cultivar was first accomplished utilizing root cuttings by the Inventor in Eustis, Fla. in 2003. Asexual reproduction by root cuttings and in vitro propagation of the new cultivar has shown that the unique features of ‘MeKong Giant’ are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘MeKong Giant’ as a new and unique cultivar of Musa.

• • 1. ‘MeKong Giant’ exhibits large green leaves with red coloration on the lower surface of the young leaves.
  • 2. ‘MeKong Giant’ is very fast growing and of large stature; reaches 3.6 to 9 m in height and about 3.6 to 6 m in spread depending on growing conditions.
  • 3. ‘MeKong Giant’ is very cold hardy and is hardy in U.S.D.A. Zones 6 to 11.
  • 4. ‘MeKong Giant’ exhibits thick trunks that are streaked with dark pink to dark maroon with age.
  • 5. ‘MeKong Giant’ exhibits large underground rhizomes with new growth returning quickly from winter dormancy.

‘MeKong Giant’ can be distinguished from its female parent, which differs from ‘MeKong Giant’ in having trunks that are light green in color and in having leaves that lack the red coloration on the lower surface of the leaves. ‘MeKong Giant’ can be most closely compared to plants of the species Musa basjoo that is similar in cold hardiness and Musa ‘Saba’ (not patented) that is similar in producing large trunks. Plants of Musa basjoo differs from ‘MeKong Giant’ in having green trunks, in lacking red coloration on the lower surface of the leaves, and in returning from dormancy less quickly. Musa ‘Saba’ differs from ‘MeKong Giant’ in being not as cold hardy and in producing green trunks.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Musa. The photographs were taken of shoots emerged from 7 year-old rhizomes as grown outdoors in a trial garden in Louisville, Ky.

FIG. 1 provides a side view of plants of ‘MeKong Giant’ in summer.

The photograph in FIG. 2 provides a view of the lower leaf surface of new leaves of ‘MeKong Giant’.

The photograph in FIG. 3 provides a view of the trunk coloration of ‘MeKong Giant’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description accurately describe the colors of the new Musa.
