What is 'Not enough'? You have posed the question 'what is the difference between evolutionary programming and genetic programming?', and the answer to this very specific question is given already in the first paragraph of the Wikipedia entry I have presented; the text also explicitly refers to the 'genetic programming', which has its own entry in Wikipedia -- both entries provide relevant references and material for further reading. If you have specific questions, then you will have to pose them explicitly; it is not feasible to respond to questions as if writing a lecture note.
In the meantime, you may wish to consult the book Introduction to Evolutionary Computing, 2nd edition, by AE Eiben, and JE Smith (Springer, Heidelberg, 2015) -- link attached below. The book discusses also genetic algorithms, as well as genetic programming.
