The concept of "conservation-selection index" was put forward based on the idea of Systematic Conservation that the conservation and selection must be combined in practice. Its calculation formula was also derived, which suits to various data and various aims of conservation and selection.
Under the conditions of random mating and selecting. The research by computer simulation analysed the possibility of long-time conserving heterozygote in colong. An important conclusion was obtained. It was impossible to conserve heterozygote for a long time in colong. Therefore it is not necessary to control inbreeding for conserving all genes of colong by reducing gene purity in the work of conserving breeds for farm animal and poultry.
