Your expression appends the new associations to the standard list, but
does not do anything with the newly created list.  You need to change
the value of auto-mode-alist.  Also, you probably want to put your new
associations before the standard ones, so you can override an existing
file type.

(setq auto-mode-alist (append '(("\\.F$" . fortran-mode)
                               ("\\.for$" . fortran-mode)
                               ("\\.txt$" . text-mode))
                              auto-mode-alist))
