You can use your seedlings as rootstocks if you can get a good scion source. The problem with growing from seed is that Avocado generally do not come true from seed, and the very heterozygous and outcrossing nature of the plant makes each seedling very different from its mother plant. So if you find a tree with good fruit and grow a tree from a seed off that good tree, the resulting plants will likely not make fruit at all similar to the parent plant, and they have a high chance of being disappointing (often with low oil and low flavor). Grafting also enables you to skip the juvenile period and get fruit much quicker (in just a few years), growing from seed make take up to 15 years to fruit the first time.
