Abstract
The present invention provides a novel semiselective medium composition for detecting seed-borne Alternaria brassicicola, which comprises galactose, calcium nitrate, dipotassium hydrogen phosphate, magnesium sulfate, agar, benomyl, and chloramphenicol. The CW medium of the present invention can selectively allow seed-borne Alternaria brassicicola to grow, while effectively suppressing the growth of other seed-borne fungi. Although A. alternata, which is prevalently present on seeds and is similar to A. brassicicola, can still grow on the CW medium, the color of the A. alternata colonies are different from that of A. brassicicola, thus, A. brassicicola can be obviously differentiated.
