Like some other crops of long domestication, the relationship of the modern soyabean to wild-growing species can no longer be traced with any degree of certainty. It is a cultural variety (a cultigen) with a very large number of cultivars.
The genus Glycine Willd. is divided into two subgenera (species), Glycine and Soja. The subgenus Soja(Moench) includes the cultivated soybean, G. max (L.) Merrill, and the wild soybean, G. soja Sieb.& Zucc. Both species are annual. The soybean grows only under cultivation while G. soja grows wild in China, Japan, Korea, Taiwan and Russia. Glycine soja is the wild ancestor of the soybean: the wild progenitor. At present, the subgenus Glycine consists of at least 16 wild perennial species: for example, Glycine canescens, and G. tomentella Hayata found in Australia, Europe, and Papua New Guinea.
Beans are classed as pulses whereas soybeans are classed as oilseeds. It is a versatile bean, having a diverse range of uses.
The English word soy is derived from the Japanese, the Japanese word for Soya sauce; soya comes from the Dutch adaptation of the same word.
