SELEGEN - A COMPUTER-PROGRAM FOR GENETIC SELECTION IN THE BREEDING OFPERENNIAL SPECIES

''Selegen'' software was developed to help tree breeding programs of f orest species, but it can also be used in breeding programs of other p erennial or semi-perennial species and animal where selection of indiv iduals is more important than selection of groups of individuals. Sele gen runs under IBM/PC-DOS and is based on algorithms which maximize ef ficiency of selection by comparing different selection methods in term s of accuracy, genetic gain, effective size of population, and genetic gain variables for each specific experimental situation. This paper p resents aspects which should be considered in methods for selection of individuals and all analysis which can be made by the program.
