A fresh weight-based method for evaluating soybean resistance to red crown rot.

ABSTRACT: Soybean red crown rot (RCR) caused by Calonectria ilicicola is a serious soil-borne disease affecting soybean production and quality. The current visual necrosis-based method for the measurement of RCR severity is prone to subjectivity as well as time consuming and laborious as it requires digging out and washing the roots to remove adhering soil prior to the visual scoring. Using cultivar Enrei, we show that, upon C. ilicicola infection, relative fresh weights (RFW; fresh weights relative to non-inoculated control plants) showed a significant negative correlation with visual RCR severity in apical shoot (trifoliate and above, R² = 0.96), shoot (unifoliate and above, R² = 0.82) and roots (R² = 0.89). Furthermore, apical shoot RFW efficiently c
