During the seed crop growing there can be also problems with uncontrolled pollination if in the previous years there was seed shedding during the harvest, which can cause growth and flowering of diploid, triploid and tetraploid plants and that can present serious problem for the next sugar beet seed crop. Meiosis of triploid hybrids is irregular and can result in development of gametes with different chromosome number. Sugar beet triploids in metaphase I have 9 univalents and 9 bivalents and therefore can be source of aneuploid gametes. After cytological analysis that was performed on 2124 meiocytes, in 14.64% different types of irregularities were detected, such as dislocated chromosomes and chromosome bridges.
