Similarity groups based on DUS variety descriptions

The determination of the most similar variety or of groups of similar varieties can be carried out using variety descriptions obtained as the result of DUS testing. A method was developed for the recognition of the most similar varieties and the similarity groups, which is demonstrated and explained on various examples. The similarity groups are affirmed principally with the help of the morphological characteristics involved in DUS testing so these similarities should be compared to the similarity data obtained using other methods and characteristics.
