I have read it before on garden websites (none come to mind at the moment) that tell growing from a seed saved from a plant in a certain geographic area will then grow better in subsequent years. kind of like adapting or evolving to that general region but we all know these take mutations and happen over a long period of time. well i just read an article about epigenetics not applied to gardening that on a cellular level animals and plants will "adapt" so to speak without actually changing dna. i found this interesting because it would then hold true that seeds saved from a parent plant should in theory be better adapted to that geographic region. sorry for my rambling but i remember seeing a question asking if bought seed mattered which geographic region it came from. now i didnt research fully so im not sure how accurate of a science epigenetics was, but i was wondering what you all thought as applied to tomato growing, and if this was true youd be more likely to save seed?
