THE USE OF BALANCED LINES FOR PRESENTATION OF MUTANTS IN ARABIDOPSIS AND OTHER PLANTS

Mutations leading to sterility or lethality can only be preserved in t he heterozygotic state. Further use of such mutations requires conside rable time and work to separate heterozygous from homozygous wild-type plants. This study shows that establishing balanced lines, by introdu cing visible markers linked in trans to such mutations, circumvents th ese disadvantages.
