Table 2.

Confusion matrices of the LDA model in training and testing sets using color and texture resources of black oat seeds obtained at 19 wavelengths (365 to 970 nm) for class membership of non-inoculated (NI) and inoculated seeds (I) with Drechslera avenae (Eidam) Sharif for 24, 72 and 120 h.

Treatment 1	Training Set (n = 480)
	NI a	I. b 24 h	I. 72 h	I. 120 h	% correct
