Long juvenility trait: A vehicle for commercial utilization of soybean ( <i>Glycine max</i> ) in lower latitudes

Abstract Soybean, a short‐day plant, has its origin in higher latitudes of China, and commercial cultivation remained confined to areas &gt;22°N till 1970s due precocious flowering accompanied with reduced biomass lower latitudes. This review summarizes the effect short days on soybean phenology, discovery novel long juvenile (LJ) trait, role breaking latitudinal boundary for production, identification genes impact LJ trait world production.
