Hi - this is my first year attempting to save seeds. I let some Aquadulce pods get black and crispy on the vine and I've attached a pic of the variations I've found. The far left one (which looks best) came from a pod which was not completely black, while the other three did. What are the black spots on the hulls of the next two and should I save those? I hulled one with black spots and it didn't seem to follow through to the eatable part. Finally, what happened to the poor little brown one on the far right?

Thanks!
