Effect of light wavelength on soybean growth and development in a context of speed breeding

Soybean [ Glycine max (L.) Merr.] breeding involves crossing and inbreeding for multiple generations to develop genetically stable lines. The long generation times cause early generations to be the major bottleneck in soybean breeding. Here we tested the effect of red and blue light (RB) and full‐spectrum white light (FS), coupled with 12‐h light (29 °C) vs. 12‐h darkness (27 °C) photothermal conditions, on the growth and development of soybean...
