Conception, formulas and method of the practical application of rejection ellipsis for individual selection in sugar beet breeding are presented in this paper. In summary the theoretical basis of rejection ellipsis may be said to rest on the decision of the rejection region of bi-variete frequency distribution such as of sucrose percentage and root weight, based on the information obtained from observation and by determining what statistical risk (θ) is or is not acceptable. Rejection ellipsis is applicable fcr bi-variete frequency distribution because it is possible to be drawn in the form of ellipsis in a plan and to apply the samples directly to this diagram. It may be also suitable fcr maintainance of varietal characteristics of various crops
