英文摘要	The genus Glycine subgenus Soja includes two species, the important crop, soybean (G. max), and its wild progenitor (G. soja), and an intermediate semiwild type (G. gracilis). However, the origin of the semi-wild type is in dispute, from independent evolutionary processes or from sympatric hybridization, although many studies support the hypothesis of a hybridization origin. Here, we reveal conclusive evidence for the natural occurrence of sympatric hybridization between wild and cultivated soybeans leading to G. gracilis by capturing natural F1 seeds based on phenotypic and molecular signatures. The F1 hybrids occurred through pollen flow between wild and cultivated soybeans, with many heterozygous loci and similar genetic parameters compared to the maternal wild populations; while paternal soybeans showed the lowest genetic diversity. The F-statistics showed genetic differentiation of the hybrids from the paternal soybeans and maternal wild populations; the differentiation of hybrids from wild soybeans was less than that of hybrids from cultivated soybeans. Natural F1 hybrids generated various seed sizes in the offspring, suggesting that cultivar-genes introgressed into wild soybeans, and the degree of outcrossing in wild soybeans seems to be very important for gene spread, exchange and recombination in the evolution of populations.
