Identifiying Cotton Germplasm with Resistance to Fusarium Wilt in Georgia

Fusarium wilt of cotton, caused by the pathogen Fusarium oxysporum f. sp. vasinfectum (FOV), is a very devastating disease of cotton in Georgia. A study was initiated in 2018 to evaluate potential germplasm sources that provide resistance to this disease. Over 430 lines were evaluated in 2018 for resistance to FOV. Resistant germplasm was then advanced for further evaluation in 2019 and in 2020. Multiple germplasm lines were identified to have medium to high resistance to FOV when compared to a standard resistant line, M-315.
