  • Apples Catalogue 2019
    ADAMS PEARMAIN Herefordshire, England 1862 Oct 15 Nov Mar 14 Adams Pearmain is a an old-fashioned late dessert apple, one of the most popular varieties in Victorian England. It has an attractive 'pearmain' shape. This is a fairly dry apple - which is perhaps not regarded as a desirable attribute today. In spite of this it is actually a very enjoyable apple, with a rich aromatic flavour which in apple terms is usually described as Although it had 'shelf appeal' for the Victorian housewife, its autumnal colouring is probably too subdued to compete with the bright young things of the modern supermarket shelves. Perhaps this is part of its appeal; it recalls a bygone era where subtlety of flavour was appreciated - a lovely apple to savour in front of an open fire on a cold winter's day. Tree hardy. Does will in all soils, even clay. AERLIE RED FLESH (Hidden Rose, Mountain Rose) California 1930’s 19 20 20 Cook Oct 20 15 An amazing red fleshed apple, discovered in Aerlie, Oregon, which may be the best of all red fleshed varieties and indeed would be an outstandingly delicious apple no matter what color the flesh is. A choice seedling, Aerlie Red Flesh has a beautiful yellow skin with pale whitish dots, but it is inside that it excels. Deep rose red flesh, juicy, crisp, hard, sugary and richly flavored, ripening late (October) and keeping throughout the winter. The late Conrad Gemmer, an astute observer of apples with 500 varieties in his collection, rated Hidden Rose an outstanding variety of top quality.

  • New Apple Cultivars with Resistance to Multiple Diseases on the Way
    NEW APPLE CULTIVARS WITH RESISTANCE TO MULTIPLE DISEASES ON THE WAY New apple cultivar development is well underway for RosBREED, thanks to a cutting-edge rapid breeding technique and application of DNA information generated in the project. Dr. Jay Norelli at the USDA-ARS Appalachian Fruit Research Station, Kearneysville, WV, is breeding apple trees with genetic resistance to scab and fire blight, two major challenges for U.S. apple growers. Apple scab is a common fungal disease managed by pesticide sprays and clearing leaf debris at season’s end. Fire blight is a bacterial disease difficult to prevent and even harder to control once an orchard is infected. Fortunately, we have sources of genetic resistance to the two diseases for breeders to use as parents. ‘Enterprise’ carries genetic resistance to both scab (Rvi6 resistance factor originally from the wild species Malus floribunda) and fire blight (FB7 source from heritage cultivar Cox’s Orange Pippin), and ‘Splendour’ carries resistance to fire blight at another genetic location (FB5, original source still under investigation). ‘Honeycrisp’ carries another resistance factor for scab (RviHC) and an allele for its characteristic crisp fruit texture, for which RosBREED has developed a DNA test (Ma-Indel). Using traditional selective breeding strategies to combine all these resistance alleles into a single Norelli’s breeding scheme for combining scab resistance, fire blight individual would take decades, even enhanced with resistance, and fruit quality traits into one apple cultivar. DNA tests. Apple trees generally don’t bloom until they’re around four years old. Even if a breeder knows a young tree would make a good parent, they must wait years to cross it.

  • Apples Variety Harvested Flavor Profile Description
    Apples Variety Harvested Flavor Profile Description Also known as Tokyo Rose, Akane is a cross between a Jonathan and a Worcester Pearmain. A small-to-medium-sized apple with an attractive bright Akane August Sweet-Tart cherry red fruit color, the juicy white flesh and sprightly flavor resemble Jonathan, but with an even more complex flavor. Ambrosia is an attractive medium-sized apple, with a pink-tinged orange/red Ambrosia October Sweet flush over a yellow background. Ambrosia’s flavor is very sweet with a crisp juiciness. A variety developed from a chance seedling in New Zealand introduced in 1952, Braeburn has a tangy flavor that straddles sweet and tart. Skin color varies Braeburn Late-October Sweet-Tart from orange to red over a yellow background. Braeburn may have Lady Hamilton & Granny Smith in its parentage. A chance seedling from the Peshastin, WA, orchard of Darrel Caudle in the 1980’s the Cameo is thought to have Red Delicious in its parentage. The skin Late Cameo Sweet-Tart has bright red stripes covering a yellow-green under color. The apple tastes as September good as it looks, with crunchy sweet-tart flavor. Cameo, which is ready in late- September, is versatile and can be eaten fresh, used in pies or in applesauce. A yellow skinned, white fleshed apple with a very sweet flavor. Discovered as a Candy Crisp October Very Sweet chance seedling in New York. Is a sweeter, crisper and juicer Golden Delicious. The Cosmic Crisp® brand apple is the remarkable result of 20 years of study and research by Washington State University’s world-class tree fruit breeding Crisp, Sweet program.

  • Apple Fruiting
    Apple Fruiting ________________________________________________________________________ Spur and Semi-spur Apple Varieties – Over 1000 spur and semi-spur varieties listed. Apple trees that have fruit on spurs or semi-spurs are more dwarfing. They also require special pruning techniques. Tip and Partial-tip Apple Varieties – Over 350 varieties listed. Fruit are borne on the tip of the branches, and are weeping and require little to no pruning. ________________________________________________________________________ Apple Fruiting 1 12/8/06 SPUR-TYPE FRUITING APPLES FOR THE HOME ORCHARD For home orchardists there are several advantages in growing spur–type trees. As the name indicates, the fruit is borne on spurs. Spurs are slow growing leafy shoots and have a mixed terminal bud. A mixed terminal bud will produce shoot and flowers. In apples, spurs develop on two–year old shoots from axillary buds located at the base of each leaf. Axillary buds on a spur can give rise to shoots or new spurs. A branched spur system forms after several years when new spur form on old spurs. Spur–type strains are more dwarfing than the standard stain. When spur and standard strains were compared in Washington rootstock trials, the spurs were 25% smaller than standard stains. Spur–type apples have a growing and fruiting characteristic in which lateral (axillary) buds on two year old wood gives rise to a higher portion of spurs and fewer lateral shoots than occur with standard growth habits. This gives the tree a more open canopy and compact growth habit than standard trees. Research indicates that they have approximately half the canopy volume of standard strains.

  • Malus Catalog
    United States Department of Agriculture Research, Education, and Economics Agricultural Research Service August 1, 2018 Dear Requestor: Enclosed is a copy of our apple or tart-cherry catalog and a disclaimer stating some of our conditions. This catalog contains a very diverse list of accessions including wild species, interspecific hybrids, heirloom cultivars, other rare cultivars and commonly available commercial cultivars. We are now suggesting that unless a request for scions (graft wood) of common commercially-available cultivars is for research purposes, we ask that you obtain that material from a commercial source. If you are not sure, there are websites that list availability such as: http://www.goodfruit.com/buyers. A general search for cultivar sources on Google can also be done. There is one excellent source that we use here when the question of commercial availability comes to us. This is an excellent book Fruit, Berry and Nut Inventory, Fourth edition: An Inventory of Nursery Catalogs Listing All Fruit, Berry and Nut Varieties by Kent Whealy. It lists many nurseries that carry not only common commercial material but also heirloom and rare cultivars published by http://www.seedsavers.org/. If accessions are not available through commercial sources, we can provide scions/cuttings. When selecting your order, the following conditions apply: 1. Orders for dormant scions (limit 25) must be received by January 10th in order to ship by March 20. 2.
