However, in some important crops like cotton, no commercially viable cultivars have been bred with sufficient resistance against black root rot. Interestingly, in Australia, researchers have identified diploid cotton species displaying marked resistance against black root rot, yet cross-breeding these traits into viable commercial crops has proven to be difficult. Similarly, researchers in Poland have uncovered innate disease resistance in the germplasm of a wild-type relative of Nicotiana tabacum called Nicotiana glauca.
