Abstract
A new cultivar of Citrus tree, ‘Gremoy79’, that is characterized by its cold hardiness and its fruit with few seeds, an easy to peel skin, and a sweet, tart flavor, and its upright rounded plant habit.
Description
Botanical classification: Citrus reticulata.
Varietal denomination: ‘Gremoy79’.
This application is co-pending with a U.S. Plant Patent Application filed for a plant derived from the same breeding program that is entitled Citrus Tree Named ‘Gremoy47’ (U.S. Plant Patent No. 23,496).
The present invention relates to a new and distinct cultivar of satsuma mandarin tree, botanically known as Citrus reticulata ‘Gremoy79’, referred to hereafter by its cultivar name, ‘Gremoy79’.
The new cultivar was derived from a controlled breeding program conducted by the Inventors in San Antonio, Tex., U.S.A. The overall purpose of the breeding program is the creation of Satsuma (mandarins) and tangerine hybrids that exhibit the fruit quality of Satsumas and the cold tolerance of select cold hardy tangerine varieties.
‘Gremoy79’ was selected by the Inventors in 2005 as a single unique tree that resulted from embryo rescue of a seed obtained from a cross made by the Inventors in 1998 between Citrus reticulata ‘Changsha’ (not patented), a tangerine, and an unnamed seedling of Citrus reticulata var. unshiu (syn, Citrus unshiu, not patented), a manderin, as the male parent.
Asexual propagation of the new cultivar was first accomplished by stem cuttings in San Antonio, Tex. in 2005 by one of the Inventors. Asexual propagation by stem cuttings has been determined that the characteristics of this cultivar are stable and are true to type in successive generations.
The following traits have been repeatedly observed and represent the characteristics of the new cultivar of Citrus.
-
- 1. ‘Gremoy79’ has been observed to be cold hardy to at least 9° F. (defoliation occurs at temperatures below about 15° F., foliage is evergreen above about 15° F.)
- 2. ‘Gremoy79’ exhibits fruit that is similar in quality to high quality Satsuma type Citrus trees with few seeds present (0 to 4 per fruit).
- 3. ‘Gremoy79’ exhibits fruit with an easy to peel skin.
- 4. ‘Gremoy79’ exhibits fruit with a sweet and tart flavor.
- 5. ‘Gremoy79’ exhibits on upright, rounded, bushy plant habit.
‘Gremoy79’ is readily distinguished from its female parent plant, ‘Changsha’. Although ‘Changsha’ exhibits slightly better cold hardiness, the fruit of ‘Gremoy79’ is much improved, as the fruit of ‘Changsha’ is less flavorful, has abundant seeds, and more difficult to peel. In comparison to the male parent, a satsuma type seedling selection, ‘Gremoy79’ is more cold hardy and the flavor of ‘Gremoy79’ fruit is more tart. ‘Gremoy79’ can be most compared to Citrus retuculata var. unshiu ‘Seto’ (not patented) and ‘Gremoy47’. ‘Seto’ differs from ‘Gremoy79’ in being less cold hardy. ‘Gremoy47’ differs from ‘Gremoy79’ in having a rounded globe plant habit, in being shorter in height and in being less cold hardy.
The accompanying color photographs illustrate the distinguishing characteristics of the new cultivar ‘Gremoy79’. The photographs were taken of the tree and fruit of an 7 year-old tree as grown in Uvalde, Tex.
The colors in the photographs are as close as possible with digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the Citrus.
The following is a detailed description of five year-old plants of ‘Gremoy79’ as grown outdoors in the ground in El Campo, Tex. with measurements of mature trees taken from plants grown in a trial plot at Uvalde, Tex. for a period of 7 years. The phenotype may vary somewhat with variations in temperature, day length, light intensity, soil types and water and fertility levels, without, however, any variance in the genotype. The color codes numbers refer to The 2007 Royal Horticultural Society's Colour Chart, London, England; except when general color terms of ordinary dictionary significance are used.
