Despite major progress in breeding and genetics, there are currently very few traits that can boost yields in Minnesota environments. Recently, we have shown that a physiological trait, consisting of maximizing daytime canopy conductance, could increase yield potential by maximizing CO2 and nutrients uptake by the crop. The Sadok lab developed a precision-phenotyping system which makes it possible to screen entire mapping populations for enhanced daytime canopy conductance. Our goal is to use this platform to identify major genes controlling this trait and introgress them in the U of M soybean breeding program. During the first two years, we identified promising variability in this trait...
