A review on somaclonal variation of Theobroma cacao L. / Ahmad Muzzammil Bakri

Theobroma cacao L. (Cocoa) is mainly grown in the tropical regions of the world, at rain forest areas and domestically cultivated for its beans production. Tissue culture is one of the important tools for plant breeding and research. The presence of somaclonal variation derived from tissue culture c...
