Test on Wilt-Resistance of Simple Hybrides F7 and Beckross Hybrid Lines F6 B1 of G. hirsutum L. of Cotton to New Virulent Isolates of Fungus Fusarium verticillioides and Verticillium dahliae

摘要

The article presents the results of studies on the resistance of hybrid cotton lines to a new virulent isolate (strain) of the fungus Fusarium verticillioides upon inoculation of the host plant. Based on the studies, it was found that the complex genotypic resistance of the studied lines, when the host plants are inoculated with isolates of -100 V. dahliae Kleb fungus and 103 Fusarium verticillioides fungi, depends on the degree of resistance of the parental forms and their combination ability.
