Claims
What is claimed is:
1. A new and distinct stevia plant as herein described and
illustrated.
Description
Genus and species: Stevia rebaudiana.
Variety denomination: `12-05-144`.
BACKGROUND AND SUMMARY OF THE INVENTION
I. Field & Utility Summary
This invention relates to a new and distinct stevia plant
designated as `12-05-144` primarily adapted to produce sweetening
agents. The new plant is characterized by a distinct steviol
glycoside profile. Stevia variety `12-05-144` is a green herbaceous
perennial which grows best in high light conditions, in
well-drained soil.
II. Cultivation Summary
The new and distinct stevia plant `12-05-144` originated from
bi-parental controlled cross of two selections from an
open-pollinated population of stevia in East Lansing, Mich. Female
parent `10-34` (unpatented) was crossed with male parent `10-19`
(unpatented), in East Lansing, in 2012. Stevia `12-05-144` was
selected from the plants resulting from the controlled cross of
`10-34` and `10-19`.
III. Comparisons
Stevia `12-05-144` Characteristics
The following traits have been repeatedly observed and are
determined to be unique characteristics of `12-05-144`, which in
combination distinguish this stevia plant as a new and distinct
plant: 1. medium stevioside concentration 2. medium rebaudioside A
concentration 3. high rebaudioside C concentration 4. low
rebaudioside D concentration 5. very high rebaudioside M
concentration 6. medium-high total steviol glycosides concentration
7. medium-high rebaudioside A percentage (w/w of total steviol
glycosides) 8. low rebaudioside D percentage (w/w of total steviol
glycosides) 9. high rebaudioside M percentage (w/w of total steviol
glycosides)
Stevia `12-05-144`, parent `10-34`, parent `10-19`, comparator
`12-05-005`, and comparator `12-05-149` differ by the following
combination of characteristics described in Table 1.

Comparator Female Parent `10-34`
Stevia `12-05-144` is distinct from female parent `10-34` in that
`12-05-144` has lower stevioside concentration, higher rebaudioside
A concentration, higher rebaudioside C concentration, lower
rebaudioside D concentration, higher rebaudioside M concentration,
higher total steviol glycosides, higher rebaudioside A percentage
(w/w of total steviol glycosides), lower rebaudioside D percentage
(w/w of total steviol glycosides), and higher rebaudioside M
percentage (w/w of total steviol glycosides) than female parent
`10-34`.
Comparator Male Parent `10-19`
Stevia `12-05-144` is distinct from male parent `10-19` in that
`12-05-144` has lower stevioside concentration, higher rebaudioside
A concentration, higher rebaudioside C concentration, lower
rebaudioside D concentration, higher rebaudioside M concentration,
higher total steviol glycosides, higher rebaudioside A percentage
(w/w of total steviol glycosides), lower rebaudioside D percentage
(w/w of total steviol glycosides), and higher rebaudioside M
percentage (w/w of total steviol glycosides) than male parent
`10-19`.
Comparator `12-05-005`
Stevia `12-05-005` (co-pending application) is a selection from the
same controlled cross of parent `10-34` and parent `10-19` from
which `12-05-144` was selected.
Stevia `12-05-144` is distinct from comparator `12-05-005` in that
`12-05-144` lower rebaudioside A concentration, higher rebaudioside
M concentration, lower total steviol glycoside concentration, lower
rebaudioside A percentage (w/w of total steviol glycosides), and
higher rebaudioside M percentage (w/w of total steviol glycosides)
than comparator `12-05-005`.
Stevia `12-05-144` is similar to comparator plant `12-05-005` in
that `12-05-144` has similar stevioside concentration, similar
rebaudioside C concentration, similar rebaudioside D concentration,
and similar rebaudioside D percentage (w/w of total steviol
glycosides) to comparator plant `12-05-005`.
Comparator `12-05-149`
Stevia `12-05-149` (co-pending application) is a selection from the
same controlled cross of parent `10-34` and parent `10-19` from
which `12-05-144` was selected.
Stevia `12-05-144` is distinct from comparator `12-05-149` in that
`12-05-144` has higher stevioside concentration, higher
rebaudioside A concentration, higher rebaudioside C concentration,
higher rebaudioside M concentration, higher total steviol
glycosides concentration, lower rebaudioside A percentage (w/w of
total steviol glycosides), lower rebaudioside D percentage (w/w of
total steviol glycosides), and higher rebaudioside M percentage
(w/w of total steviol glycosides) than comparator `12-05-149`.
Stevia `12-05-144` is similar to comparator `12-05-149` in that
`12-05-144` has similar rebaudioside D concentration to comparator
plant `12-05-149`.
IV. Breeding History
The new and distinct stevia originated from a controlled cross of
the stevia selection `10-34` (female parent;
unpatented).times.stevia selection `10-19` (male parent;
unpatented). This cross was made and the resulting seedlings grown
in East Lansing, Mich. The present seedling was selected from the
controlled breeding program in 2012 and was designated
`12-05-144`.
V. Asexual Reproduction
Stevia plant `12-05-144` has been asexually propagated by cuttings
since 2012 and was established in tissue culture in 2013 in East
Lansing, Mich.
VI. Stability
Asexual propagation as described has demonstrated that the
combination of traits that characterize this plant are fixed and
remain true to type through at least five successive
generations.
BRIEF DESCRIPTION OF THE FIGURES
The accompanying color photographs show typical specimens of the
new plant at various stages of development as nearly true as it is
possible to make in color reproductions. Color in the photographs
may differ slightly from the color value cited in the detailed
