To quote from the GNU Emacs Lisp Reference Manual, Edition 1.03, Section
20.1.3 entitled "How Emacs Chooses a Major Mode Automatically", the variable
auto-mode-alist is described:

        This variable contains an association list of file name 
        patterns...and corresponding major mode functions.  Usually,
        the file name patters test for suffixes...

        Here is an example of how to prepend several pattern pairs to an
        existing auto-mode-alist.  (You might use this sort of expression in
        your '.emacs' file.)

          (setq auto-mode-alist
            (append
             '(("/\\.[^/]*$" . fundamental-mode) ; Filename starts with a dot.
               ("[^\\./]*$" . fundamental-mode)  ; Filename has no dot.
               ("\\.C$" . c++-mode ))
             auto-mode-alist))

So, this example shows that the following should do what you want:

          (setq auto-mode-alist
            (append
             '(("\\.F$" . fortran-mode)) ; Filename ends in ".F"
             auto-mode-alist))
