The selection of tolerant variants to race 1 fusarium wilt of banana was carried out through the effects of fusaric acid on in vitro banana multiple bud clumps (MBCs). The MBCs of Maca cultivar (Musa sp., AAB, Silk), which is susceptible to the race 1 fusarium wilt, were used. And, Nanicao cultivar (AAA, Cavendish subgroup) was used in the tolerant tests as control of a disease tolerant variety. Firstly, to aim at determining an appropriate concentration of the toxic for the tolerant selection, the MBCs were cultured on the Modified Murashige & Skoog medium supplemented with 0.05 to 1.6 mM fusaric acid. The growth on both cultivars was completely inhibited on the medium containing 0.1 mM fusaric acid. Tolerant variants of Maca were, Then, selected with 0.1 mMfusaric acid after chemical mutagen treatment. The results showed an increased tolerance of the selected Maca plants to the race 1 fungus ingreenhouse tests. In vitro selection by fusaric acid is a very useful method for obtaining fusarium disease tolerance, although the tolerance mechanism of the selected plants may be different from that of existing tolerant cultivars. |
