      Cultivar Records:
      -----------------
      Each cultivar is presented individually as a formatted record.  The  
      first line of each record indentifies the cultivar by it's recognized 
      true name.  Other information listed may include the name 
      abbreviation, true growth habit, specie scientific epitaph, other
      names or synonyms by which it has been known, accession numbers, full
      pedigree and production acreage in the United States.  Additional
      information is presented in reprints of Agronomy Journal and Crop
      Science registration statements.  The information presented only
      pertains to the development and release of the individual cultivars,
      with no information concerning continued testing of agronomic
      performance or quality presented.  Other information also can be
      readily obtained for most cultivars from other sources identified in
      the reference section of this publication.
 
      True Growth Habit:
      ------------------
      "Spring" wheats produce grain from spring plantings, and do not
      possess a vernalization requirement.  "Winter" wheats are planted in
      the fall for grain production, develop some level of cold tolerance
      and must be vernalized to produce grain.  A few cultivars are
      identified as "facultative" types, capable of producing grain from
      either fall or spring plantings.  See 'Market Class' discussion
      concerning fall-planted hard red spring wheats.
 
      Market Class:
      -------------
      Each cultivar is identified within one of seven market class 
      designations according defined by the USDA Federal Grain Inspection 
      Service (FGIS); durum wheat, hard red spring wheat, hard red winter 
      wheat, hard white wheat, soft red winter wheat, soft white wheat and 
      unclassed/mixed classes.  Fall-planted hard red spring wheats grown 
      and marketed as hard red winter wheats in the southwestern United 
      States are listed among the hard red spring wheats.  Soft red wheats 
      possessing spring or facultative growth habits are categorized as soft 
      red winter wheats.  Wheats considered either unclassed or mixed 
      according to FGIS guidelines are grouped together in a seventh 
      category that includes wheats belonging to species other than Triticum 
      turgidum var. durum (durum wheats) and T. aestivum (the common 
      wheats), or common wheats with mixed kernel characteristics (e.g. 
      Bluebird 2) that cannot be classified according to the FGIS 
      designations.
