Abstract

The research conducted in RUE “Research and Practical Centre of NAS of Belarus for Arable Farming’’ showed the dependence of polymorphism of buckwheat varietal populations both on ploidy and on determination of growth processes in apical meristems. At lower positive temperatures, the populations of tetraploid samples have 3.7 times more long seedlings than the populations of diploid samples. This will allow to better keep heterozygosity in newly formed populations due to the higher number of parents, which is very important for cross-pollinated species (Fagopyrum esculentum Moench.).
