The relationship between microgametophyte's and sporophyte's properties has been studied in carrot, cabbage, and flax specimens. The analysis of the carrot pollen showed a significant diversity of in vitro pollen viability. Modern methods of mathematical analysis (factorial, discriminant) revealed the similarity in the distribution of pollen grain properties in all studied crops and their genotypical variability in the flax and carrot (with a high reliability level in the latter case). The study of 25 flax specimens showed that the pollen grain size and the portion of immature grains declined from wild to crown flaxes. The distribution of the mature pollen size in the fiber flax showed a positive excess, while the development of immature pollen stopped earlier as compared to that of wild and crown flax. The possible use of pollen properties for the evaluation of plant adaptability has been discussed
