Current methods of improving yam are inadequate and thus plant scientists have begun to search for alternative regeneration materials, using biotechnology methods. These include the use of leafy vine cuttings and the culture of leafless nodal explants, leading to the production of uniform plantlets. Meristem culture is being used, especially for virus elimination. The culture of excised leaves, true seed, and zygotic embryos elimanates problems associated with the handling of large tubers. Somatic embryogenesis has been achieved in some species, and somaclonal variants arising in culture could form a basis for yam improvement. Tuber regeneration in culture clearly demonstrates the viability of non-tuber sources as useful alternatives for yam regenerationSubject(s): FITOMEJORAMIENTO | DIOSCOREA | CULTIVO DE TEJIDOS | CULTIVO DE MERISTEMAS | CULTIVO DE CELULAS | HIBRIDACION | BIOTECNOLOGIA
