Induction of polyploidy in citrus rootstocks

The present investigation was undertaken to Induction of polyploidy in citrus rootstock through Colchicine Treatment. Seed were immersed in different concentrations of colchicine treatments (0, 0.2%, 0.6%, 1.2%) for different rootstock (Citrange, Citromelo and Sour orange). The seedling ploidy was determined via flow cytometry. Higher colchicine concentrations decreased the survival. Mixoploeid Citrange produced by 0.6% Colchicine treatment. Morphological data confirmed the results of flow cytometry. The mixoploid from Citrange can be used for breeding programs
