Developing Somaclonal Variation of Bogor Taro to Expand the Diversity of Character

Authors:Bobby Brain, Jason Stuart


Taro (Colocasia esculenta (L.) Schott) is a monocot which is included in the Araceae Family, and one of the staple foods as a source of carbohydrate. In the framework of breeding, the diversity of traits is required, and the induction of somatic mutation is one of the technical options utilized. The aim of this study was to develop somatic asexual variation of botanic mites to expand the diversity of traits, leading to the production of new genotypes that were then propagated to meet the needs of quality seeds. Top bud culture of the botanic taro was induced by gamma ray irradiation at 0, 5, 10, 15 and 20 Gy. The results showed that γ-rays had an effect on the number of leaves, and had the greatest effect at 10 Gy dose, but had no effect on shoots. Compared with the parental, the induction of somatic clonal variation produced up to 51% diversity.
