An expression is derived for the efficiency of a selection index based on ancestor records, meas ured as the correlation between index and true additive genetic merit. The maximum efficiency for in ite generations of ancestors is obtained and compared with the efficiency of using only one or two generations. Comparisons are also made with the use of sibling records, performance testing and progeny-testing. Author
