Seed degeneration

Topic:

Pathology, Seeds

Definition:

“1) “”Reduction in yield or quality caused by an accumulation of pathogens and pests in planting material due to successive cycles of vegetative propagation.””

2) “In vegetatively propagated crops, pathogens tend to accumulate if planting material is drawn from within a crop population over multiple generations, resulting in significant quality and yield losses.””
