PLANT breeders have generally assumed that nuclear effects are more important than maternal effects in governing character expression. There is little doubt that this has been a valid assumption. On the other hand, numerous examples are known of maternal inheritance and reciprocal differences in plants. The present study was conducted to ascertain whether maternal effects on seedling vigor could be detected in crosses among diverse alfalfa plants selected for adaptation to northeastern United States. In addition, an effort was made to identify certain factors that contributed to maternal effect on seedling vigor.
