摘要： Genetic adaptation of soybean phenological stages to high-latitude long-day environments is the major pre-requisite for enhancing regional plant-based protein production. Both E-genes controlling flowering and growing environment determine timing of flowering and maturity, and E-gene composition might differ between Chinese and European soybeans bearing the potential for improving adaptability. Therefore, 140 early maturity elite soybean cultivars of either Chinese or European origin were genotyped for the E1 to E4 flowering loci, and genotypes were tested across 17 European environments spanning a latitude range from 45 to 52 degrees N in order to determine effects of various E-allele combinations. Differences in E-allele composition between Chinese and European cultivars were largest for the loci E1 and E3. Wild-type alleles significantly delayed flowering, and effects of particular E-alleles were depending on geographic latitude. Consequently, photoperiod-insensitive E-haplotypes carrying several non-functional alleles proved to be suitable for cultivation in higher latitudes, whereas photoperiod-sensitive late-maturity E-haplotypes are adapted to lower latitudes only. Thus, breeding for new E-haplotypes through combining Chinese and European alleles could enhance the potential for further soybean adaptation to northern growing regions.
