¹Correlations were calculated from schemes in which no selection was practiced; ²standard errors are about 0.004; ³standard errors increase from about 0.0040 in year 2 to about 0.0110 in year 20; BB is the method developed in this paper and BER is the method developed by Bienefeld, Ehrhardt and Reinhard [5].
