Molecular marker indel15-1 of soybean early-flowering-season major QTL (quantitative trait locus) and application thereof

The invention discloses a molecular marker indel15-1 of soybean early-flowering-season major QTL (quantitative trait locus) and application thereof. The soybean early-flowering-season major QTL is positioned on the 48600kb-49850kb interval of the soybean 15th chromosome Gm15, and the molecular marker is positioned on the 49588kb of the soybean 15th chromosome Gm15. The forward primer sequence of the molecular marker is Seq ID NO.1, and the reverse primer sequence is Seq ID NO.2. Among the two groups of materials with different early flowering seasons in the NJZNRIL population amplified by the primers and the newly prepared secondary population, the material containing 180bp specific DNA segment has a larger early-flowering-season phenotypic number. The molecular marker disclosed by the invention can be used for screening or identification of the length of the early flowering season for soybean varieties or lines, thereby enhancing the breeding efficiency. 本发明公开了大豆始花期主效QTL的分子标记indel15-1及其应用。本发明大豆始花期主效QTL位点位于大豆
