Expanding soybean planting is vital for food security both in China and globally. The 50° N latitude serves as the northern boundary of major regions. However, enhancing adaptability to photothermal conditions enables potential extend cultivation higher latitudes altitudes. Understanding genetic basis super-early maturity crucial achieving this goal. In study, 438 germplasms collected from high-latitude regions were evaluated Heihe (HH) (50°15' N, 127°28' E, 154 m), Beijicun (BJC) (53°28' 122°21' 295 m) Labudalin (LBDL) 120°19' 577 m). Using resequencing data, we analyzed natural variation haplotypes 35 key genes associated with flowering time maturity. results showed that relative groups (RMGs) BJC, HH, LBDL -1.0, 0.0, -1.2, respectively. Among analyzed, 23 had identical allelic variations, while 12 exhibited 19 SNPs four InDels. Functional mutations identified E1, E2, E3, E4. Notably, all cultivars carried e1-as allele which likely critical adaptation. Additional included a single-base substitution E2 (16142 A > T) E3 (5203 C T), causing premature codon termination, along frameshift E4 (3726 4099) (2649). Haplotype analysis revealed significant differences growth stages among nine gene haplotypes. frequency early-maturing BJC highlights role accumulation These findings offer valuable insights improving expanding its China.
