This ripened over the weekend and we ate it while camping at the Northwest String Summit (a music festival near Portland, OR). This is what this cultivar looks like when completely ripe, with just the faintest yellow blush on green:
I didn’t take any photos of it cut because it was so messy, but here’s the seed and the seedling I found inside the seed (compass is included because it has inches & cm marked):
Looks mono-embryonic to me, so probably zygotic rather than a clone. Also looks like it might have some kind of black mold on it? Either way, it was a delicious mango and I’m excited to get scionwood from my brother to graft this on my greenhouse tree.
