WebMay 23, 2024 · Successful chromosome doubling is essential for genotypes with low spontaneous doubling rates. Therefore, to generate enough plants for artificial chromosome doubling, the optimum concentration of colchicine was analyzed. HS-S was selected as it had the lowest doubling rate of the four selected genotypes. WebFor example, for development of herbicide-resistant brassicas, the active chemical is introduced in the culture medium after mutation treatment (Beversdorf and Kott, 1987), and, after chromosome doubling, the surviving plants could be raised under controlled conditions and later screened for this trait. Similarly, effective selection could also ...
