Abstract:
The study was conducted for screening for 26 cotton genotypes for relative susceptibility/resistance against jassids laid out in All India Coordinated Cotton Improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri, during Kharif season of the year 2020 and 2021. Among 26 genotypes 19 moderately resistant genotypes, 4 susceptible genotypes and 4 highly susceptible genotypes are recorded. The trichomes were compared against jassids incidence whereas higher trichomes are observed in resistant cotton genotypes than the susceptible cotton genotypes. Jassids infestation is more in susceptible genotypes than in resistant genotypes. In conclusion, trichomes confers a resistance against jassids incidence in cotton genotypes.
