Screening of Diploid Cotton Genotypes against Fusarium oxysporum f. sp.Vasinfectum

Cotton wilt incited by Fusarium oxysporum f.sp. vasinfectum is one of the most serious disease inflicting unaccountable quantitative as well as qualitative losses. A total of 310 diploid cotton genotypes were evaluated under glasshouse and field conditions. Results showed that all the genotypes screened, exhibited varied degree of reactions against F. oxysporum f.sp. vasinfectum. Among 310 Diploid cotton genotypes, only six showed resistant reaction and twenty genotypes showed moderately resistance reaction in seedling resistance reaction. Out of these 26 cotton genotypes, 8 genotypes showed resistant reaction in Adult Plant Resistant Test.
