Micropropagation of sugar cane in Ecuador
Journal Title: Biotecnología Vegetal - Year 2009, Vol 9, Issue 4
Abstract
Ecuador is a country where sugar cane (Saccharum spp. hybrid) exceeds 82 000 ha for sugar production. The Research Center of the National Union of sugar cane farming in Ecuador (UNCE) is plotted as objective to obtain plants of different varieties by micropropagation, to multiply quickly and efficiently, genotypes with excellent performance under the conditions of production and result in a high quality certified seed and plant genetics. It were used as initial explants shoots, of the varieties ‘Cenicaña 1985-1992’ (CC85-92), ‘Ragnar’, ‘BJ 7046’, ‘CR 74-250’, ‘SP70-1143’, ‘PCG 12 745’ ‘RD7511’ and ‘Mexico 73-0523’. The obtained seedlings were multiplied, rooted and acclimatised. Then be planted in areas where sugar cane is grown in the country. In the case of the variety ‘Ragnar’ planted an area of approximately 0.3 ha, which was determined yield (ton/ha). Micropropagation of selected varieties allowed to obtain 268 600 plants in 12 months. It was found that the varieties showed differences in their rates of multiplication. The survival of plants in the acclimatization phase was higher than 88.0%. The harvest for the experimental plot planted with the variety ‘Ragnar’ contributed 55 tons. This equates to an output of 183 ton/ha. These values are much higher than the national average. The results confirmed the non-appearance of diseased plants or Scalding RSD. These results are one of the first reports for Ecuador from the use of biotechnological methods, being the pioneers in the mass propagation of sugarcane plants.
