摘要： Appropriate flowering and maturity time are important for soybean production. Four maturity genesE1,E2,E3andE4have been molecularly identified and found to play major roles in the control of flowering and maturity of soybean. Here, to further investigate the effect of different allele combinations ofE1-E4, we performed Kompetitive Allele Specific PCR (KASP) assays based on single nucleotide polymorphisms (SNPs) at these fourEloci, and genotypedE1-E4genes across 308 Chinese cultivars with a wide range of maturity groups. In total, twenty-one allele combinations forE1-E4genes were identified across these Chinese cultivars. Various combinations of mutations at fourEloci gave rise to the diversity of flowering and maturity time, which were associated with the adaptation of soybean cultivars to diverse geographic regions and farming systems. In particular, the cultivars with mutations at all fourEloci reached flowering and maturity very early, and adapted to high-latitude cold regions. The allele combinationse1-as/e2-ns/e3-tr/E4,E1/e2-ns/E3/E4andE1/E2/E3/E4played important roles in the Northeast China, Huang-Huai-Hai (HHH) Rivers Valley and South China regions, respectively. Notably,E1andE2, especiallyE2, affected flowering and maturity time of soybean significantly. Our study will be beneficial for germplasm evaluation, cultivar improvement and regionalization of cultivation in soybean production.
