  • This year, Cornell University released three new apple varieties: the scab-resistant Cordera, the crisp and mild Pink Luster, and the complexly flavored Firecracker.
  • To begin breeding a new apple like the Pink Luster, breeders start by looking at different apples’ traits they want to combine to make a crossbreed that contains the best attributes of two parent apples, sometimes looking at DNA markers to target certain desirable genes.
  • Out of the thousands of rootstocks Fazio works with, many are killed early on either because they just don’t grow well or they don’t stand up to the diseases with which they’re inoculated.
