Somatic Hybridization for Plant Improvement

  • Chapter

Abstract

Since the concept of somatic hybridization in plants was first developed in the early 70’s there has been great expectation of the impact that it could make to plant breeding. These expectations were generated by the idea of gaining access to nuclear genes that were beyond sexual boundaries and also by the possibility to do breeding of the cytoplasmic genomes, both with phylogenetically near and distant species. This chapter attempts to review the progress to date and to examine the reasons why the expectations have so far been largely unsatisfactory. We will argue that there has in fact been extensive progress and that useful new germplasm is now beginning to emerge. The progress is the consequence of developments in a number of areas: new fusion methods, better heterokaryon selection strategies, better protoplast culture methods and more powerful molecular tools for analysing the hybrids. Hopefully with these first dividends of application will come a renewed interest and investment in this technology.
