Bigger is not always better: Optimizing leaf area index with narrow-leaf shape in soybean.

Abstract excerpt

Modern soybean (Glycine max) varieties have higher than optimal leaf area index (LAI), which could divert resources from reproductive growth. Altering leaf shape could be a simple strategy to reduce LAI. To test this, we developed 204 near-isogenic lines differing in leaf morphology by introgressing the ln allele that confers the narrow-leaf trait from 2 donor parents (PI 612713A and PI 547745) into the elite,...
