Exploring the differences between organic and conventional breeding in early vigour traits of winter wheat

Breeding for organic systems may be done as pure line or population breeding. Early vigour, critical to organic systems, was compared for different winter wheat breeding origins in a hydroponic system, as well as in the field. Entries were: the F15 of composite cross populations (CCPs), based on high yielding (Y), high quality (Q) or Y*Q varietal intercrosses after 11 generations evolving under organic management; four organically bred; four...
