Evaluation of soybean [Glycine max (L.) Merr.] genotypes for yield, water use efficiency, and root traits.

Drought stress has been identified as the major environmental factor limiting soybean [Glycine max (L.) Merr.] yield worldwide.

Characterization of a soybean (Glycine max L. Merr.) germplasm collection for root traits.

Root systems that improve resource uptake and penetrate compacted soil (hardpan) are important for improving soybean (Glycine max L. Merr.) productivity in optimal and sub-optimal environments.
