The apples on the left are a yellow variety and those on the right are a green. The yellow has little disease resistance similar to a tame apple but the green on the right is highly disease and insect resistant. Both are medium sized apples. I used the quarter for size reference. The green on the right is to me better flavored both sweet and sour like Fuji. The yellow is more sweet and course or mealy like a Rome. Time will tell how they do. Many of you have seen some of my other seedling apples or other fruits and a few people are growing them. My goal has always been to improve and preserve rare fruit varieties. In the case of these apples they are genetically diverse as they are wild apples grown from seed.
