If wild muscadine can pollinate the particular type I have then they might not be self fertile. I live in an area that is rural and wild muscadine are everywhere. I have heard 90% of wild vines are male but I'm unsure how true that might be. There are wild females around. Most of which have small purple black fruits. I have found a few with larger fruits but not quite as large as the ones I'm growing most often. I did find one with near marble sized fruits with distinctly pink skin. Fruit isn't large but ok flavor for a wild vine. However tastes are subjective and I'm one of those that can eat nearly anything and enjoy it to some extent. I like wild persimmon, muscadine, sand pears, etc and will eat them no problem at all. I eat the skins and seeds of muscadine no problem chewing the seeds not just swallowing them. I crunch through and enjoy Duncan white grapefruit seeds and all as bitter and numerous as the seeds can be. No qualms at all about that sort of stuff most wouldn't or couldn't do. It's a nutritional thing in my mind too I guess. The best phytonutrients and other bioactive compounds are highest in the parts most discard in many cases. That said I can acknowledge what would be considered a "good" fruit to those with much more picky tastes.
