Abstract: The present invention provides a stevia plant having a genotype C/C at a position corresponding to position 37 of SEQ ID NO: 1. The present invention also provides a method of producing the stevia plant, and an extract obtained from the plant.

Abstract: A method of screening for a stevia plant with high steviol glycoside content, that includes detecting from the genome of a test stevia plant the presence and/or the absence of the following genetic feature: (1) homozygous for the allele wherein the base at the position corresponding to position 290 of SEQ ID NO: 1 is T, and the presence and/or the absence of the following genetic feature: (2) homozygous or heterozygous for the allele wherein the base at the position corresponding to position 40 of SEQ ID NO: 2 is A.

Abstract: The present invention provides a high sweet content stevia plant having a variation at a portion corresponding to SEQ ID NO: 1, a method of producing or screening for the same, etc.

Abstract: A method of screening for a stevia plant with high rebaudioside M content ratio, that includes detecting from a test stevia plant the presence and/or absence of at least one of (1) and (2), and at least one of (3) to (7): (1) homozygous for the allele wherein position 290 of SEQ ID NO: 1 is T; (2) homozygous for the allele wherein position 33 of SEQ ID NO: 2 is A; (3) homozygous for the allele wherein position 44 of SEQ ID NO: 3 is T; (4) homozygous for the allele wherein position 40 of SEQ ID NO: 4 is T; (5) homozygous for the allele wherein position 48 of SEQ ID NO: 5 is C; (6) homozygous for the allele wherein positions 55-72 of SEQ ID NO: 6 are deleted; (7) homozygous for the allele wherein position 50 of SEQ ID NO: 7 is A.

Abstract: Provided is a plant having at least one of genetic characteristics (A)-(E) below. (A) Alleles in which the base at the position corresponding to position 40 of SEQ ID:1 is C are homozygous or heterozygous. (B) Alleles in which the base at the position corresponding to position 21 of SEQ ID:2 is T are homozygous or heterozygous. (C) Alleles in which the base at the position corresponding to position 28 of SEQ ID:3 is T are homozygous or heterozygous. (D) Alleles in which the base at the position corresponding to position 59 of SEQ ID:4 is C are homozygous or heterozygous. (E) Alleles in which the base at the position corresponding to position 64 of SEQ ID:5 is T are homozygous or heterozygous.

Abstract: The present invention provides a Stevia plant comprising useful steviol glycoside such as rebaudioside D at higher content as compared with known Stevia species. The present invention also provides a method of producing such a Stevia plant, and a dried leaf and an extract obtainable from such a plant.

Abstract: The present invention provides a high sweet content stevia plant having a variation at a portion corresponding to SEQ ID NO: 1, a method of producing or screening for the same, etc.

Abstract: The present invention provides a high rebaudioside M content non-genetically modified stevia plant comprising rebaudioside M at higher content as compared with the wild type stevia species. The present invention also provides a method of producing such a high rebaudioside M content non-genetically modified stevia plant, and a dry leaf obtainable from such a plant.
