Enhancing the efficiency of disease resistance breeding in cotton using marker technology

Principal Researchers

Dr Iain Wilson, Dr Qian-Hao Zhu and Dr Danny Llewellyn.

Executive Summary

Working in close cooperation with the Cotton breeders, the disease marker group has had a successful year that moves us closer to developing more disease resistant germplasm.

Molecular markers have been developed and validated for CBT, bacterial blight and okra leaf. These are now routinely used in the Cotton Breeding process. This technology will greatly enhance the ability of the breeders to make significant gains in the future.

Disease markers for diseases such as Black Root Rot, Verticillium Wilt and Fusarium Wilt are currently being identified and validated and should be able to accelerate the development of new cultivars carrying resistance.

Markers have been found that are diagnostic for the recessive fuzzless seed trait and a paper on the genetics of the recessive fuzzless seed trait has been published.
