It is feasible to identify specific phenotypic criteria indicative of robust root architecture that can be implemented in canola breeding programs and for designing effective management practices. Yet, the roles of roots in N absorption (responsible for nitrogen use efficiency; NUE), root anchorage strength (involved in lodging resistance and yield stability) and associated genotypic variations are not well understood.  we have recently developed a non-destructive electrical capacitance measurement and a 2-dimensional digital imaging method for examining the dynamics of root system architecture. The applications and limitations of the capacitance measurement method for assessing the responses of canola crops to abiotic stress will be discussed.
