48、y wheat midge are considered unsound grains (3.5.2) only when more than half the surface of the back of the grain is coloured grey to black as a result of secondary cryptogamic attack. Where discoloration covers less than half the surface of the back of the grain, they are classed as grains damaged

49、by pests. 3.3.4 grains with discoloured germ, mottled grains grains either a) with discoloured germ in which the tegument covering the germ is coloured brown to brownish black and in which the germ is normal and not sprouted; Note 1 to entry: If the germ is coloured only with one little spot, the grain is considered sound. Note 2 to entry: This fraction only exists for common wheat and durum wheat. Note 3 to entry: For common wheat these grains are disregarded up to 8 %. or b) mottled which show a brown to brownish black disco
