Summary

An analysis of germination characteristics of progeny from a diallel cross between five sugar-beet plants showed that the genotype of the maternal parent controlled to a marked extent the behaviour of the progeny. This may be related to the presence in the fruits of inhibitory substances.

Some evidence was found for genie and maternal interactions but these were always of less importance than the maternal effects. Heritability estimates from parent, off spring regression and analysis of half-sib family variances demonstrated that genetic variation for germination characteristics had not been eliminated during the improvement of sugar beet from the wild form.
