Abstract: KNOWLEDGE of genetic parameters is useful in designing efficient breeding systems. Estimation of genetic parameters raises the problem of suitable material as a source of data. Until recently, genetic parameters in poultry populations have been estimated from data collected from inbred lines or selected populations. Estimates obtained from inbred lines have required correction factors in order to compensate for changes in genetic variance due to inbreeding. In addition, few of these inbred lines were developed without considerable natural and/or artificial selection. Estimates obtained from non-inbred populations under artificial selection have ignored, for the most part, the bias which may result from the use of selected parents in the typical variance components analysis. Correction for the reduction of genetic variance in selected parents by the use of adjustment factors is very difficult or even not feasible with the accuracy one desires. Even when selection is for only one or a few…
