>>2534970Apple trees from seed will almost all bear sub-par and wildtype fruit. They tend to be small, sour, and good only for making cider. They're edible, but they'll make you long for a proper McIntosh red or a Fuji.
It's a consequence of apple genetics. There's two things to know about this:
1. You get a random selection of apple genetics from both parents. Two good parents will probably yield something marginally better than two poor parents, but even that isn't guaranteed. You have a strong change of getting a tree with tiny sour fruit. Applies do not grow true to type and they do not have a lot of desirable and dominant fruit genes. Most of the "good ones" are recessive traits that disappear when crossbred. This means breeding for new apple varieties is time (and money) intensive.
2. Apples cannot self-pollinate. Because all typed varieties [e.g. Fuji] are close to genetically identical, they cannot and will never be able to pollinate other trees of the same variety. If you're thinking of growing apple trees, you should know that you need at leas two different varieties, preferably three, because without a second type of apple to pollinate with, your apple tree will yield no fruit.
