Sorting Through The Variability


The current axiom is that passage of plant cells through tissue culture results in increased genetic variability. The major task confronting anyone who would harness this new genetic variability is to recover the rare, desirable genotypes from the large number of other genotypes. This task is accomplished easily if the desired phenotype is controlled by a single gene, and expressed at the cellular level in vitro. Tolerance of plants to stresses often do not exhibit these characteristics. We will consider several approaches to developing novel selection systems for complex, agricultural traits.
