| description | This paper deals with the description and evaluation of a method of colchicine treatment called "Tiller Injection Method" to obtain duplication of chromosome number in wheat (Triticum aestivum L.) x rye (Secale cereale L.) hybrids. Emmasculations and crossings to obtain the F1 hybrids were manually performed. "Tiller Injection Method" with "Modified Crown Method" were compared in the first year of evaluation. There were no significant differences in the statistical analysis of the number of polyploid plants obtained with both methods; however, great differences were observed in the colchicine consumption, it being notably lower when using the "Tiller Injection Method". Thus, this method allows a large number of plants to be treated with a lower drug concentration. In the following two years, only the "Tiller Injection Method" was used. Treatment efficiency increased in the third year of the experiment, thus yielding better results. |

Se describe y evalúa un método de tratamiento con colchicina denominado "Método de Inyección en Macollas", para la duplicación del número de cromosomas en híbridos de trigo (Triticum aestivum L.) por centeno ( Secale cereale L.). Se efectuaron a mano las emasculaciones y los cruzamientos para la obtención de las plantas híbridas F,. En el primer año de evaluación se compara el "Método de Inyección en Macollas" con el "Método de Corona Modificado". Los resultados de plantas poliploides logradas con ambos métodos no expresan diferencias significativas en el análisis estadístico, pero si se observan importantes diferencias en el consumo de colchicina, siendo notablemente menor en el "Método de Inyección en Macollas". Este método permite por lo tanto tratar un gran número de plantas con una concentración más baja de la droga. En los dos años siguientes se utiliza sólo el "Método de Inyección en Macollas". La eficiencia de los tratamientos se incrementa en el tercer año del experimento, lográndose los mejores resultados.
