A cluster analysis of wild and domesticated soybean phenotypes

Article

Summary

Cluster analysis techniques were used to examine phenotypic variation within the USDA Soybean Germplasm Collection. This study included ten Plant Introductions each of the domesticated soybean, Glycine max (L). Merr., the ‘wild’ soybean, G. sojaSieb. & Zucc., and a disputed species, G. gracilisSkvortz.G. max and G. soja were found to be morphologically distinct entities and G. gracilis was found to be conspecific with G. max. Because G. gracilis probably represents weedy races associated with the cultivated soybean and because ‘gracilis’ phenotypes can be distinguished from G. max, the designation, G. max forma gracilis, is recommended.
