Abstract
The present invention provides a stevia plant having a low ability to form pollens as compared with the wild type stevia species. The present invention also provides a method of producing such a stevia plant having a low ability to form pollens, and an extract or a steviol glycoside purified product obtainable from such a plant.
Claims24
A stevia plant having a low ability to form pollens as compared with the wild type.
A method of screening for a stevia plant with a low ability to form pollens, comprising a step of detecting from the genome of a test stevia plant the presence and/or the absence of a genetic feature of being heterozygous or homozygous for the allele wherein the base at the position corresponding to position 79 of SEQ ID NO:
- 151 is C, being heterozygous or homozygous for the allele wherein the base at the position corresponding to position 65 of SEQ ID NO:
- 152 is T, and/or being heterozygous or homozygous for the allele wherein the base at the position corresponding to position 24 of SEQ ID NO:
- 153 is T.
A screening kit for a stevia plant with a low ability to form pollens, comprising a reagent for detecting the presence and/or the absence of a genetic feature of being heterozygous or homozygous for the allele wherein the base at the position corresponding to position 79 of SEQ ID NO:
- 151 is C, being heterozygous or homozygous for the allele wherein the base at the position corresponding to position 65 of SEQ ID NO:
- 152 is T, and/or being heterozygous or homozygous for the allele wherein the base at the position corresponding to position 24 of SEQ ID NO:
- 153 is T.
A method of producing a stevia plant with a low ability to form pollens, comprising a step of introducing a variation from T to C to a position corresponding to position 79 of SEQ ID NO:
- 151, a step of introducing a variation from A to T to a position corresponding to position 65 of SEQ ID NO:
- 152, and/or a step of introducing a variation from A to T to a position corresponding to position 24 of SEQ ID NO:
- 153.
