The results of 42-year research on apple breeding at the polyploidy level to produce triploid varieties are provided. A brief description of their forms – the diploid gamete donors is given. It is found that for practical breeding of triploid varieties the more valuable are the following types of crossbreeding: 2х х 4х х 2х as they result in 69.5% and 55.1% of triploid seedlings, respectively.
