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.

Stevia plant having high rebaudioside M content ratio and screening method for same

The present invention provides aplant having a low ability to form pollens as compared with the wild typespecies. The present invention also provides a method of producing such aplant having a low ability to form pollens, and an extract or a steviol glycoside purified product obtainable from such a plant.

Stevia plant having less ability to form pollens

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.

High steviol glycoside-containing stevia plant and method for screening same

The present invention provides aplant having a low ability to form flower buds as compared with the wild typespecies. The present invention also provides a method of producing such aplant having a low ability to form flower buds, and an extract or a steviol glycoside purified product obtainable from such a plant.
