Let R be a commutative ring , the pseudo – von neuman regular graph of the ring R is define as a graph whose vertex set consists of all elements of R and any two distinct vertices a and b are adjacent if and only if , this graph denoted by P-VG(R) , in this work we got some new results a bout chromatic number of P-VG(R).
