"Plant variety testing through field experiments and subsequent statistical evaluations provide necessary information for variety entry in national and international registers. A newly registered variety must possess unique properties making it distinct from other already registered varieties. It must be uniform, stable and provide original characteristics, which set it above the current level of production potential. Qualified decision-making about variety registration is conditioned upon availability of relevant information. The current paper describes the process of creating a support system for decision-making (DSS) to assist planning and evaluations of field experiments according to guidelines set by the National Plant Variety Office of Central Institute for Supervising and Testing in Agriculture. The decision support system shall represent a powerful instrument to provide assistance in the area of quantitative analysis, a part of the variety testing and evaluations. DSS generates optimum design of field experiments through suitable placement of varieties in field trial plans and secures the follow-up statistical analysis of the experimental results. The paper describes statistical and mathematical methods implemented in original or modified form and focuses on modules of the decision support system as a whole. Issues of validating the implemented algorithms are discussed. The DSS system was implemented in the MATLAB language and supplied with suitable user interface."@en . "6"^^ . .
