Hi... I bought some banana peppers today that turned out to be Hungarian. They were wonderfully hot, so I saved the seeds. But I started wondering if they will germinate. I'm drying them out... but should I save them, or am I wasting my time?
I'd plant a few right now in a pot to see if they will grow. If the pepper was ripe enough they will grow. If they won't grow you can throw them out. What you get will depend on their parents. I suspect you'll get some kind banana pepper that will vary in hotness and other aspects from one plant to another.
I'd urge you to save any info you can recall, like the name of the fruit stand and exact date. If you really love the result, you may want to be able to refer back to it like it was an orchid-collecting expedition up the Amazon.
I suspect that many comemrical crops are hybrid, for the uniformity and productivity. But SOME hybrids have fairly uniform offspring, and if tjhey don't, some will probably be better than the parents for your particular taste, soil and climate.
