Root architecture characterization in relation to biomass allocation and biological nitrogen fixation in a collection of European soybean genotypes☆

Soybean [Glycine max (L.) Merr] is the legume with the largest cultivated area worldwide and its yield depends largely on symbiotic nitrogen fixation and root architecture. This study aimed to explore the genetic variability of root architectural traits and di-nitrogen fixing activity in a small col...
