ABSTRACT
Chickpea (Cicer arietinum L.) is an important food legume. In Pakistan, yield potential of chickpea is low due to the prevalence of Fusarium wilt. Present investigations were conducted at Arid Zone Research Institute, Bhakkar, Punjab, Pakistan during winter 2021. Experiment was laid out in Randomized Complete Block Design (RCBD) following three replications. Thirty chickpea genotypes were examined for their resistant levels against Fusarium wilt caused by Fusarium oxysporum ciceris (FOC). Six exhibited resistant response with <10% disease incidence and seven genotypes were moderately resistant (11-20% DI) against wilt pathogen. However, five genotypes recorded moderately susceptible response (21-29% DI) and five genotypes showed susceptible response (30-50% DI) moreover; the remaining seven genotypes expressed highly susceptible response with maximum percent disease index (PDI) (>50%). Maximum and minimum disease incidence was recorded on CH-32/10 (7.26%) and D-15024 (69.61%) genotypes, respectively. It is concluded that chickpea resistant genotypes including CH-32/10, TG-1410 identified in present study might be helpful in different breeding programs against wilting pathogen. Among six fungicides (Fosetyle aluminium, Derosal, Shinkar, Ridomil gold, Cabrio Top, Acrobate) Fosetyle aluminium caused maximum disease reduction (75.16%) at the concentration of 3 g/liter of water followed by Derosal carbendazim) (65.76), Shinkar (59.44), Ridomil gold (52.41), Cabrio Top (44.17) and acrobat (41.86) respectively on comparison to control. Results are also helpful for the farmers for timely management of fusarium wilt.
