title: Improvement of Vitis vinifera sativa D. C. taxonomy
abstract: A method of mathematical statistics for evaluation of the taxonomic usefulness of characters included in the Vitis vinifera sativa D. C. cultivar clustering has been developed. The method works as follows: The irregularity of the distribution of characters in taxons is calculated, and the probability of achieving such estimates is calculated when all taxons are assigned to the same general population after a certain character. The method does not depend on the type of the distribution of charact
