Abstract
Abstract A method has been developed for the determination of total glucosinolate content in rapeseed. Following selective hydrolysis of glucosinolates by the endogeneous myrosinase in rapeseed, the glucose produced is detected with commercially available glucose test strips. The intensity of the colour on the strips is measured using a portable reflectometer. This method is suitable for use by plant breeders and for the determination of glucosinolate content in commercial rapeseed loads.
