Screening of cotton mutants for the resistance against cotton leaf curl virus (CLCuV)

Cotton germplasm representing twenty two mutants against one positive control S-12 was screened for resistance to CLCuV. BLGT inoculation was found useful in identifying CLCuV resistance. None of the mutant screened through grafting respond immune or highly resistant, while M-811, M-115, PIM-76-8, M...

Description
Summary:Cotton germplasm representing twenty two mutants against one positive control S-12 was screened for resistance to CLCuV. BLGT inoculation was found useful in identifying CLCuV resistance. None of the mutant screened through grafting respond immune or highly resistant, while M-811, M-115, PIM-76-8, M-388 and M-564 behaved resistant. Moreover, PIM-76-1 and PIM-76-1 a, were as highly susceptible as S-12. In contrast, screening under natural conditions was most useful for identifying insect resistant germplasm. Most of the mutants that were resistant or moderately resistant under BLGT inoculation were found immune or highly resistant under natural conditions. None of the test mutants was found susceptible or highly susceptible under field conditions.
