Abstract:
The article reveals the results of initial surveys on the determination of resistance potentials of several varieties and lines of medium-fiber cotton plant selected as primary material in the research work conducted on the development of new varieties resistant to Fusarium oxysporum f.sp.vasinfectum and Fusarium solani pathogenic fungi which in recent years have caused significant damage to the yield of cotton varieties grown in large areas of the republic. According to the analysis, UzFA-707 and UzFA-710 varieties showed the highest resistance to Fusarium oxysporum f.sp. vasinfectum mycotoxins, and UzFA-713 and Yulduz varieties showed the highest resistance to Fusarium solani fungi. In the future, it is recommended to conduct scientific research to study the resistance of these varieties to fusarium wilt in field experiments |
