Using 131 sib-mated lines of buckwheat, Fagopyrum esculentum Moench, the homozygous genetic load for viability was estimated by a modification of the Morton-Crow-Muller (1956) method, under favorable and unfavorable environmental conditions. Two kinds of genetic load, designated A and B, were estimated to be 0.225 and 0.653 in favorable conditions, and 0.343 and 2.623 in unfavorable conditions, respectively. Concealed genetic variability has been maintained within the cultivated buckwheat
