A goal of the presented paper was the crop productivity estimation of dihaploid and double haploid plants after apozygotic (uniparental) reproduction of heterosis hybrid. Methods. 8 dihaploid apozygotic progenies of heterosis hybrid Lenturon and 11 double haploid progenies were investigated. In the investigated material were evaluated (i) crop productivity (t/ha), (ii) sugar content in root (%), (iii) sugar yield. Results. Dihaploid progenies don’t register a reduction of crop productivity. Some of progenies even exceed a result of the initial hybrid. Double haploids register also a high level of crop productivity, but this material show greater variability. Conclusions.This result shows a possibility using of apozygotic progenies for breeding purposes. A use of uniparental (apozygotic) reproduction makes it possible to enlarge the genetic diversity of breeding materials. Key words: crop productivity, sugar beet, genetic diversity of breeding materials, dihaploid and doubled haploid plants.
