Research Article Cassava Periclinal Chimera Vigor: A theory on its origin

Abstract

Cassava Periclinal chimera plants could be synthesized by a very easy grafting method. Thanks to this technique we can produce vigorous plants during a very short period. This can be achieved by grafting two types that have high combining ability. The most striking feature is that we can obtain enormous roots up to five times the common ones. It is suggested this vigor is due to gene action of overdominance and there is DNA movement from epidermis (one cell layer tissue) to internal tissues. Previous results are explained in view of this present one.
