The coefficient of parentage between two strains is a useful estimate of genetic similarity. Many researchers have used a FORTRAN program developed by D.M. Rodgers and T.S. Cox, where the inbreeding coefficient of all strains is assumed to be unity. This note describes SAS programs, derived from their program, that (i) accommodate variation in inbreeding coefficients among strains, (ii) use a computer package that is familiar to many plant breeders and runs on mainframe or microcomputers, (iii) provide selective output, and (iv) provide summary statistics of the coefficient of parentage values of each selected strain with all other selected strains.
