| description |
Micropropagation efficiency determination of cassava (Manihot esculenta, Euphorbiaceae) genotypes of interest to the Northeast of Argentina. In vitro cassava propagation has been reported in numerous studies; however, the efficiency of multiplication had only been established in a very restricted number of cultivars and / or subcultures during micropropagation. In order to evaluate the in vitro multiplication of 20 economically important cassava cultivars of Northeast Argentina (six total subcultures performed every 30 days), uninodal segments were cultured in basal Murashige and Skoog (1962) supplemented with 0.01 mg/L of 1-naphthaleneacetic acid, 0.01 mg/L of 6-benzylaminopurine and 0.1 mg/L gibberellic acid. Plant regeneration was possible in 100% of the cultivars during the 6 subcultures. Regardless of the subculture, the average number of nodes regenerated per explant varied significantly among cultivar from two to five nodes per plants (P?0,0001). The average number of accumulated nodes was significantly different among cultivars with values that ranged from 46 to 16,568 nodes per plants (P?0,0001). Results show variability due to genotype, distinguishing three cultivars groups according to their propagation efficiency and growth in length ability. Determining the multiplication rate of different cassava cultivars is essential for optimizing micropropagation. |

Micropropagation efficiency determination of cassava (Manihot esculenta, Euphorbiaceae) genotypes of interest to the Northeast of Argentina.

En la bibliografía se citan numerosos trabajos de propagación in vitro de mandioca, sin embargo sólo se ha establecido la eficiencia de la multiplicación para un número muy restringido de cultivares y/o subcultivos durante la micropropagación. El objetivo de este trabajo fue evaluar la multiplicación in vitro de 20 cultivares de mandioca de interés económico para el Nordeste Argentino (6 subcultivos totales realizados cada 30 días). Para ello, se cultivaron segmentos uninodales en medio basal de Murashige y Skoog (1962) más 0,01 mg/L de ácido 1-naftalenacético, 0,01 mg/L de 6-bencilaminopurina y 0,1 mg/L de ácido giberélico. Todos los cultivares evaluados regeneraron plantas durante los 6 subcultivos. Independientemente del subcultivo, el número promedio de nudos regenerados por explante varió significativamente con el cultivar (P?0,0001), rondando valores de 2 a 5 nudos por planta. El número promedio de nudos acumulados fue significativamente distinto dependiendo del cultivar, alcanzando valores de 46 a 16.568 nudos totales por plantas (P?0,0001). Los resultados demuestran variabilidad debida al genotipo, distinguiéndose 3 grupos de cultivares en relación a su capacidad de propagación y crecimiento en longitud. La determinación de la tasa de multiplicación de distintos cultivares de mandioca es fundamental para la optimización de la micropropagación.
