Heritability of Fiber Strength in Genetically Engineered Cotton
Feb 8, 2019

WCRC WCRC2 Breeding

Fiber strength must be increased for cotton to remain competitive as a textile fiber. The findings of a 2-yr study of cotton genetically engineered to express increased fiber strength are reported. Particle bombardment transformation of 'Deltapine 50' was accomplished by Monsanto. In field trials, fiber strength was increased by 25-75% over the non-transformed Deltapine 50. However, inconsistent expression of strength may prevent commercialization of cotton germplasm derived from this transformation. These data may have general implications for transgenic breeding in that transformation events imparting inconsistent expression of the value added trait should be discarded early in the breeding process
