The invention belongs to the technical field of soybean genetic breeding, and particularly relates to a KASP marker related to detection of soybean grain
fat content and application of the KASP marker. The invention provides a KASP marker S1045008520 related to detection of the soybean grain
fat content, the KASP marker S1045008520 is located at the 45008520th basic group position of a No.10
chromosome of a soybean
reference genome Glycine max Wm82.a2.v1 and has
nucleotide polymorphism A / T, the grain
fat content of a soybean sample with the KASP marker
genotype being TT is remarkably higher than that of a soybean sample with the KASP marker
genotype being AA, and the TT has the fat content increased by 0.67%-1.17% relative to the AA fat content. The KASP marker technology is used for performing
genotype analysis on soybean samples, the detection is accurate and efficient, the sample
genotyping is convenient and stable, the fat content of soybean seeds is rapidly pre-judged in the early growth stage of soybeans,
molecular marker-assisted selection with
high fat content as a breeding target is realized, the breeding selection precision is improved, and the breeding efficiency is improved. The method has important application value in accelerating the soybean fat content
molecular breeding process.
