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

A method of screening for a stevia plant with high rebaudioside M content ratio, comprising detecting from the genome of a test stevia plant the presence and/or the absence of at least one of the following genetic features (1) and (2), and the presence and/or the absence of at least one of the following genetic features (3) to (7):

• (1) homozygous for the allele wherein the base at the position corresponding to position 290 of SEQ ID NO:
• 1 is T;
• (2) homozygous for the allele wherein the base at the position corresponding to position 33 of SEQ ID NO:
• 2 is A;
• (3) homozygous for the allele wherein the base at the position corresponding to position 44 of SEQ ID NO:
• 3 is T;
• (4) homozygous for the allele wherein the base at the position corresponding to position 40 of SEQ ID NO:
• 4 is T;
• (5) homozygous for the allele wherein the base at the position corresponding to position 48 of SEQ ID NO:
• 5 is C;
• (6) homozygous for the allele wherein the portion corresponding to positions 55-72 of SEQ ID NO:
• 6 is deleted;
• (7) homozygous for the allele wherein the base at the position corresponding to position 50 of SEQ ID NO:
• 7 is A.
