Obtaining new cultivars of Colocasia taro are a priority of the Genetic Improvement Program of the crop. The selection of plants and their evaluation with the participation of the producers has become one of the main ways to achieve this objective. For this reason, in the Plant Biotechnology laboratory of INIVIT, in vitro cloning was carried out by tissue culture techniques of a Colocasia taro plant selected as a possible mutant, through participatory research, within a commercial plantation of the cultivar 'Cameroon 14' at the “Horquita” Agricultural Company, located in Abreus municipality, Cienfuegos province. The plants produced in vitro were planted under field conditions and the evaluation of the morphoagronomic characters was carried out by applying the descriptors of this species. As a result, it was determined that the plants multiplied in vitro presented different characteristics to the donor when evaluated using the established descriptors and, therefore, it turned out to be a new cultivar, which was registered as 'INIVIT MC-2012' in the Commercial Variety Registry of the Ministry of Agriculture. In the harvest carried out 10 months after planting, this genetic material reached a yield of 25 t ha-1, was less affected by dry rot and showed good culinary quality in corms and cormels.

Keywords : tissue culture; participatory research; genetic improvement.
