Red Delicious 

  The Red Delicious is a clone of apple cultigen, now comprising more than 50 cultivars, 
  that was recognized in Madison County, Iowa, United States, in 1880. As new cultivars 
  with improved color and earlier harvestability have replaced the original cultivar in 
  commercial orchards, the taste and texture of the harvested commodity have deteriorated, 
  and many customers have begun to reject the Red Delicious at the food market.[1] Roger 
  Yepsen notes some of the Red's less desirable qualities. "The skin is thick and bitter 
  and has to be chewed vigorously... this apple ranks close to the bottom when cooked... 
  sold year round, so shop with skepticism. Delicious retains its cheerful good looks long 
  after its flavor has departed.

  Gala 

  Gala is a clonally propagated apple with a mild and sweet flavor.
  Gala apples ranked at number 2 in 2006 on the US Apple Association's 
  list of most popular apples.

  Granny Smith

  The Granny Smith green apple is a tip-bearing apple cultivar, which originated in 
  Australia in 1868. It is named after Maria Ann Smith, who propagated the cultivar 
  from a chance seedling. The tree is thought to be a hybrid of Malus sylvestris, 
  the European Wild Apple, with the domestic apple M. domestica as the polleniser. 
  The fruit has hard, light green skin and a crisp, juicy flesh. In some parts of 
  Canada the Granny Smith is referred to as a Green Delicious.  Granny Smiths go 
  from being green to turning completely yellow and looking almost like Golden 
  Delicious after 4 to 5 months postharvest. The acidity mellows significantly, 
  and it then takes on a balanced flavor.

  Golden Delicious
  
  The Golden Delicious is a cultivar of apple with a yellow color. It is not closely 
  related to the Red Delicious apple.  Golden Delicious is a large, yellow skinned 
  cultivar and very sweet to the taste. It is prone to bruising and shriveling, so 
  it needs careful handling and storage. It is a favorite for salads, apple sauce, 
  and apple butter.  This cultivar is a chance seedling possibly a hybrid of Grimes 
  Golden and Golden Reinette. The original tree was found in 1891 on the Mullins' family 
  farm in Clay County, West Virginia, United States and was locally known as Mullin's 
  Yellow Seedling and Annit apple. Anderson Mullins sold the tree and propagation rights 
  to Stark Brothers Nurseries, which first marketed it as a companion of their Red 
  Delicious in 1914.

  McIntosh

  The McIntosh Red is an apple cultivar with red and green skin, a tart flavor, and 
  tender white flesh. It ripens in late September. It is traditionally the most popular 
  cultivar in Eastern Canada and New England, well known for the pink applesauce unpeeled 
  McIntoshes make. It is also well-suited for cider and pies.   Every McIntosh apple has 
  a direct lineage to a single tree discovered in 1811 by John McIntosh on his farm in 
  Dundela, a hamlet near Morrisburg, in Dundas County, Ontario, Canada. He discovered 
  the tree as one of 20 apple seedlings while clearing the farm, which he had just 
  purchased. He transplanted the seedlings, cultivated them, and only one of them was 
  still alive by 1830. The surviving apple tree lived until 1906. The oldest surviving 
  descendant also died on the 25th July, 2011.

  Braeburn

  The Braeburn is a cultivar of apple that is firm to the touch with a red/orange 
  vertical streaky appearance on a yellow/green background. Its color intensity 
  varies with different varieties. They are known to have a burst of flavor when 
  bitten into.  It is believed to have been discovered as a chance seedling in 1952 
  by the farmer O. Moran from Waiwhero in New Zealand. It was cultivated by the nursery 
  Williams Brothers to export this variety of apple. It is thought to be a cross between 
  Granny Smith and Lady Hamilton. The apple itself is named after Braeburn Orchard where 
  it was first commercially grown.

  Cripps Pink ("Pink Lady")

  Cripps Pink is a variety of apple, from which apples meeting quality standards can 
  be sold under the trade mark name Pink Lady. The Cripps Pink variety was originally 
  bred by John Cripps at the (then named) Western Australia Department of Agriculture 
  in 1973 by crossing the Australian apple Lady Williams with a Golden Delicious in 
  order to combine the best features of both apples. The apple is both sweet and crisp.
