Can I say that RPART is a modified algo of CART and PARTY a modified of CHAID?
Not truthfully. CART is a trademark of commercial software. rpart (sic) is similar but not 'modified' from anything -- it is an independent implementation of the ideas in Breiman, Friedman, Olshen and Stone (with some extra ideas by Terry Therneau and others).
party (sic) is very much more general than CHAID.
