POWDERY MILDEW RESISTANCE MARKER OF MELON PLANT, POWDERY MILDEW-RESISTANT MELON PLANT, AND METHOD FOR PRODUCING POWDERY MILDEW-RESISTANT MELON PLANT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a novel powdery mildew resistance marker of a melon plant, a powdery mildew-resistant melon plant comprising a powdery mildew resistance gene locus, and a method for producing a powdery mildew-resistant melon plant using the same.SOLUTION: A powdery mildew resistance marker of a melon plant comprises a homozygous powdery mildew resistance gene locus on a sixth chromosome and satisfies at least one of the following conditions (1) and (2). The condition (1): the powdery mildew resistance gene locus on a sixth chromosome is specified by the length of an amplified fragment amplified with a specific primer set, where the amplified fragment has a length greater than 133 bases, the primer set consisting of forward and reverse primers each having specific base sequences. The condition (2): the powdery mildew resistance gene locus on the sixth chromosome is a disease resistance gene locus specified by a polymorphism of bases 45, 48, 49, 51, 108, 120, 139, 214, and 327 in a specific nucleotide sequence.SELECTED DRAWING: None
