a few years ago Cornell figured out how to gentically engineer known apple cultivars so that the subsequent clones will be fireblight resistant. This is not a new cultivar that has been genetically engineered to be fireblight res, it is a method used to make known cultivars FB res.
So, I thought you'd like to know, those of you who are against GMO foods and for choice in what we eat and grow, you should be on the lookout for cultivars that have previously been fireblight susceptible but advertised as FB res.
I do not know the present state of this technology, if cultivars are presently being modified for this gene transformation but, if past experience with GMO is any indication, it could be snuck into our nursery trees and food supply with no warning or label.
Here is an excerpt from the patent office:

United States Patent 6,100,453
Aldwinckle , et al. August 8, 2000
Inventors: Aldwinckle; Herbert S. (Geneva, NY); Norelli; John L. (Ithaca, NY)
Assignee: Cornell Research Foundation, Inc. (Ithaca, NY)
Appl. No.: 021520

Transgenic pomaceous fruit with fire blight resistance

Abstract
The present invention relates to a method of conferring resistance against fire blight to pomaceous fruit scion or rootstock cultivars by transforming such cultivars with a gene which encodes for lytic proteins. Such transformation can be effected by bacterial infection or propulsion of particles into cell interiors. Once transformation has taken place, the cultivar is regenerated to a transgenic pomaceous fruit tree. This technique is particularly useful in treating apple and pear cultivars.

For apples, the following cultivars can be treated in accordance with present invention to impart fire blight resistance: Adina, Akane, Anna, Antonovka, Arkansas Black, Bancroft, Beacon, Beaujade, Belle de Boskoop, Big Time, Blushing Golden, Braeburn, Bramley's Seedling, Britegold, Champion, Chenango, Chieftain, Cleopatra, Connel Red, Coromandel Red, Cortland, Cox's Orange Pippin, Crispin, Criterion, Dayton, Delicious (including Red Delicious), Democrat, Discovery, Dorsett Golden, Dulcet, Earliblaze, Earlidel, Earligold, Early Cortland, Ein Shemer, Elstar, Empire, Empress, Fameuse, Fiesta, Florina, Freedom, Fuji, Gala, Galaxy, Geneva Early, Gingergold, Gloster, Golden Russet, Golden Delicious, Golden Supreme, Granny Smith, Gravenstein, Greensleeves, Grimes Golden, Haralson, Hauguan, Haushuai, Honeygold, Hatsuaki, Himekami, Hokuto, Idared, Iwakami, James Grieve, Jerseymac, Jonafree, Jonagold, Jonagored, Jonalicious, Jonamac, Jonared, Jonasty, Jonathan, Jonnee, Jored, Karmijn, Kitakami, Laxton's Superb, Liberty, Lodi, Lurared, Lysgolden, Macoun, Maigold, McShay, McIntosh, Melrose, Mollies Delicious, Monroe, Northern Spy, Northwestern Greening, Nova Easygro, Novamac, Orin, Ozark Gold, Paulared, Pink Lady, Prima, Prime Gold, Primicia, Princessa, Priscilla, PureGold, Ralls Janet, Raritan, Red Baron, Redchief, Regent, Reine des Reinettes, Reinette du Canada, R.
