Estimation of Fusarium Head Blight of Triticale Using Digital Image Analysis of Grain

The response of spring triticale to the infection of heads with mixture of Fusarium culmorum and F. avenaceum isolates was investigated with the application of colour image analysis of grains. The results seem to suggest that there is a strong relationship between declining values of the two yield components: kernels weight per spike and one thousand kernels weight (TKW), and the values of colour components H S and I (hue, saturation, intensity); the presence of the relationship is confirmed by high values of simple correlation coefficients. The technique applied in the experiment makes it possible to diagnose a case of Fusarium infestation at a nearly 90% probability, the result that creates the basis for further research towards the elaboration of a completely automatic system of colour image analysis of grain.
