Definitions

  • Genus and species Stevia rebaudiana.
  • Stevia rebaudiana is a plant species in the sunflower (Asteraceae) family, which has naturally sweet leaves.
  • the active compounds that impart the sweet flavor to stevia leaves are steviol glycosides.
  • the most common steviol glycosides are stevioside and rebaudioside A, both of which have up to 250 to 400 times the sweetness of sugar.
  • Stevioside tends to be more prevalent in unimproved lines of stevia leaves than rebaudioside A.
  • the development of new varieties of Stevia rebaudiana with higher levels of rebaudioside A than stevioside is desirable for use as a sugar substitute.
  • the present invention relates to a new and distinct variety of Stevia rebaudiana, the 'SW 20 ⁇ line, which has very sweet leaves with high levels of steviol glycosides and very low bitterness and aftertaste, excellent overwintering, high plant vigor, high leaf yield, and late flowering.
  • the 'SW 20 ⁇ line was derived in 2012 from a single plant in a population of recurrently selected Stevia rebaudiana, the population of which was originally grown from seed in an outdoor field in Chowchilla, California, USA, under natural lighting.
  • the plant that produced the 'SW 20 ⁇ line was selected from its population based upon the following characteristics, which were measured and/or observed between 2012 and 2014.
  • Leaf Taste The leaves of the 'SW 20 ⁇ line were found to have an excellent sweet taste in comparison to a majority of the plant population from which the line was derived and very little bitterness and aftertaste in comparison to most stevia varieties.
  • Overwintering The 'SW 201 ' line was found to have superior overwintering in comparison to the majority of the plant population from which the line was derived, the latter of which died over the course of the winter.
  • Steviol Glycosides The leaves of the 'SW 20 line were found to have high levels of steviol glycosides (over 18%) with rebaudioside A accounting for over 60% of the total steviol glycoside content in the leaves (see, Table 1).
  • the 'SW 20 line was asexually reproduced from rooted cuttings in May 2012. Plant yield and leaf quality of the 'SW 20 line were confirmed in April through October 2014 through replicated yield trials in the following three locations: Yuma, Arizona; Indio, California; and Ontario Oregon. At each of the three locations, the performance of the 'SW 201 ' line grown from cuttings was compared to seedlings grown from bulk commercial seed ("the check variety"). Table 1 compares various characteristics of an average sampling of leaves of the 'SW 201 ' line with an average sampling of leaves of the check variety.
  • the 'SW 201 ' line contained more rebaudioside A (11.17% vs. 6.85%); less stevioside (5.29 vs. 6.42%); more total steviol glycosides (18.04% vs. 14.71%); a higher rebaudioside A to stevioside ratio (2.19 vs. 1.11); and a higher percentage of rebaudioside A to total steviol glycosides (60.9% vs. 46.8%).
  • the 'SW 201 ' line also produced 22 % more leaf yield than the check variety with the ' S W 201 ' line producing 4, 129 lb of leaf per acre per year versus 3,386 lb of leaf per acre per year for the check variety.
  • Leaf yield results were averaged over three locations with four replications at each location, and two harvest strategies (one or two cuttings per year). The higher yield of the 'SW 20 line was due in part to low stand loss from Fusarium and other root diseases that reduced plant stand of the check variety.
  • FIG. 1 depicts a color photograph of a fully mature 'SW 20 ⁇ Stevia plant from roots to top of the plant near the end of the plant's first growing season.
  • FIG. 2 depicts a color photograph of 'SW 20 ⁇ leaves.
  • FIG. 3 depicts a color photograph of an 'SW 20 ⁇ leaf, including the shape and dimensions.
  • FIG. 4 depicts a color photograph of the flowers of an 'SW 20 ⁇ Stevia plant.
  • Width (including flowers). 75 cm.
  • Width 1.0 cm - 2.0 cm.
  • Petiole length -0.6 cm.
  • Petiole diameter -0.3 cm.
  • Rebaudioside A as a percentage of total steviol glycosides. 60.9%.
  • Ratio of rebaudioside A to stevioside 2.19.
  • Leaf harvest period Summer and/or Fall.
  • Length (excluding inflorescence). Varies to lm.
  • Petal length ⁇ 0.6cm.
  • Anther length -0.4 cm.
  • Anther color RHS 199A. Gynoecium.
  • Style color RHS 155B.

Abstract

L'invention concerne une nouvelle variété particulière de Stevia rebaudiana, dénommée SW 201. Cette nouvelle variété se distingue d'autres variétés de Stevia par le goût remarquablement sucré de ses feuilles, sa très faible amertume et sa quasi-absence d'arrière-goût, sa très bonne capacité d'hivernage, sa grande vigueur, son rendement élevé en feuilles, sa floraison tardive et ses niveaux importants de glycosides de stéviol.
