| Sumario: | 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. |
