Apple Tree Variety Spreadsheet. 1.30.14

I put together this spreadsheet for my apple varieties.  It takes time to find info about pollen compatibility, disease resistance, heritage.   Sources are mainly raintreenursery.com (RT) and orangepippin.com (OP).  Not the best spreadsheet but the program is free via google (checkmate Microsoft!)
