Abstract
Cross-fertility of a single cross hybrid was found to decrease gradually in advanced generations. When the same parents were selfed without selection for two or three generations, seed setting increased from Syn1 to Syn2, then decreased in Syn3 and Syn4. Interpretation of these data according to various genetic models, assuming no epistasis, indicates that fertility is influenced more by the mother plant than by the zygote, especially in the F1. Even with the best model, deviations from regression remain significant, except when the Syn1 generation is removed from the analysis.Keywords
