Abstract
AUTOTETRAPLOIDS of buckwheat obtained in 1941 by means of colchicine treatment showed variation with regard to fertility1. Owing to the vast amount of initial material it was possible to isolate in the variety Bolshevik individuals which were genotypically highly fertile. They differed in this respect from other experimentally produced autotetraploids the fertility of which was sharply reduced, some of them being even entirely sterile. Reduced fertility in autotetraploids depends primarily on irregular chromosome distribution in meiosis, leading to the formation of aneuploid micro- and macrospores and consequently to pollen abortion, poor seed setting and to the appearance of polysomics.
