To perform genetic studies with any organism, it is imperative that a source of variation be available. In the past variation has come from wide crosses, germplasm collection and utilization, mutagens, and sports. With the advent of tissue culture protocols, variation has been ubiquitious. The variability associated with tissue culture has provided a pool of variation upon which selection pressure has been imposed to isolate unique forms of clones, this variation, known as somaclonal variation, has become important for plant improvement, but the genetic basis of this variation remains largely unknown. In this chapter we will explore different types of variation and then discuss relevant investigations that have been used to elucidate the genetics of the variation.
