Selection of Soybeans Using Average Canopy Coverage

Summary

Purdue University researchers have developed a selection method that helps soybean breeders and seed companies who want to increase rate of grain for yield, increase return on investment from R&D, and/or market varieties with precision metrics. Researchers used field images to measure soybean canopy development from phenological stage V2 to R5, i.e., growth stages. Variance component analysis indicated that a parameter, described as average canopy coverage, is a highly heritable trait with a promising genetic correlation with grain yield, enabling indirect selection of yield via canopy development parameters. Fast canopy coverage is an early season trait that is inexpensive to measure and has great potential for application in breeding programs focused on yield improvement.
