Abstract

Biochemical markers use proteins variability to study the plants genetic diversity and to evaluate the phylogenetic relationships of accessions, populations, subspecies, species of cultivated and wild plants. The biochemical techniques are rapid, accurate and dependable. They have been revealed to be useful in: ensuring the genetic relations between plant taxa, evaluation of the genetic diversity, phylogenetic relationships, germplasm geographical origin, new cultivar identification and description and saving time in the tests of distinctness, uniformity, stability of a candidate cultivar. Moreover, they are utilized in new variety registration and applications of plant variety rights. The current mini-review will focus on consideration of biochemical analyses in plant systematic from the early era up to now, giving more attention to the used techniques.
