Abstract:
Field experiment on evaluation of cotton genotypes against Jassid resistance was conducted at All India Coordinated Cotton Improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri, during kharif season of the year 2020 and 2021. The 23 cotton genotypes were selected from the All India Coordinated Cotton Improvement Project, MPKV, Rahuri and studied for categorizing this selected cotton genotypes for jassids resistance by comparing to standard checks i.e., Resistant checks (Ajeet 155 and NDLH 1938) and susceptible check (DCH - 32). Results are based upon Jassids count where among 26 genotypes, 19 cotton genotypes are moderately resistant, 4 genotypes are susceptible and 3 genotypes are highly susceptible cotton genotypes. Jassid injury grade also recorded for particular genotype.
