Apparent photosynthesis (AP), transpiration (TR) and seed yield were determined under field conditions for three near‐isogenic lines (isolines) of ‘Clark’ soybeans ( Glycine max (L.) Merr.) differing in pubescence. AP of fully expanded leaves near the top of the plant and TR of individual plants were measured during the flowering stage. Seed yields artd AP rates were not affected by pubescence but the dense pubescent isoline had lower transpiration rates than the normal or glabrous isoline.
