Evaluation of fineness of wrinkles on husks of malting barley (Hordeum vulgare L.) by texture analysis of digital image data

Summary It has been suggested that the selection based on the wrinkles on the husks of malting barley is useful especially during the early generation in breeding program, because the wrinkles can be an indicator of malting quality of grains. However, it can be done only visually and requires much labor. In this study, the evaluation of the wrinkles by texture analysis of digital image data, was examined for the quantitative evaluation of the fineness of the wrinkles and its automatic selection. The texture analysis based on co-occurrence matrices was applied and it was revealed that finely wrinkled grains can be clearly discriminated by discriminant analysis on several parameters estimated from the co-occurrence matrices.
