Abstract
A POLYHAPLOID seedling with eighteen chromosomes has been found among the offspring of cytologically controlled tetraploid plants of sugar beet. The plant survived the winter months and developed a number of seed stalks in the following spring. At flowering time the plant was isolated in a greenhouse and, in addition, one branch was bagged. Despite the fact that the original diploid variety was classified as self-sterile, the new diploid (polyhaploid) plant set a number of seeds and proved to be partially fertile1.
