Mathematical methods use for result estimation of breeding achievements trials for distinctness, uniformity and stabilit

«OIL CROPS» Scientific bulletin, VNIIMK, 2006, is 2 (135). A possibility of mathematical methods use for estimation of results of parental line and hybrids trials for distinctness, uniformity and stability is shown. The method for calculation of confidence intervals on quality traits for untypical plants portion is chosen. A possibility of taxonomic analysis application for precise calculation of likeness relations among the variety samples is studied. The method chosen for evaluation of error possibility when variety belonging to individual plants is determined by quantitative traits.
