Abstract

An experiment was conducted to evaluate bacterial wilt resistance among different brinjal genotypes in Department of Plant Pathology, OUAT, Bhubaneswar during 2021-2022. Twenty five brinjal genotypes were screened by artificial inoculation with Ralstonia solanacearum inoculum at a concentration of 1.5 × 108 cfu/ml. Among them Utkal Keshari was highly resistant followed by Utkal Anushree, BB-67, Kanta Bagan and Arka Neelkanth. The variety Hazari Local showed wilt symptoms 50 days after inoculation (2.42%). Nayagarh spiny brinjal (1.56%), BB-67 (1.16%) showed wilt symptoms at 40 days after inoculation. Kanta Bagan (1.86%), Utkal Jyoti (1.17%), VNR-5 (3.57%) exhibited wilt symptoms 30 days after inoculation. Dhenkanal Local (1.49%), Utkal Anushree (1.84%), Utkal Tarini (3.33%) showed wilt symptoms 20 days after inoculation.

Conclusion

Twenty seven brinjal varieties were screened due to excess application of pesticides are being challenged now a days due to raising concerns about toxic substances causing soil pollution and health issues. Yet it is not feasible due to the development of antibiotic resistance. So that most promising strategy to combat the wilt disease is to develop resistance in the host plant. Based on the above findings, Utkal Keshari was highly resistant followed by Utkal Anushree, Kanta Bagan and Arka Neelkanth lines were found to be resistant. These genotypes can be used in breeding programme for developing resistance against bacterial wilt of brinjal.
