Abstract
Leaf curl virus disease is a most destructive threat to chilli production. In the present investigation 54 chilli genotypes were screened for leaf curl virus resistance in the natural epiphytotic field conditions and artificial inoculation using viruliferous white flies at Horticulture Research and Extension Centre (University of horticulture science, Bagalkot) during 2020-2023. The genotypes DCA-262, Khandhari and Bhoot Jolokia were found to be immune and genotypes EC 391087 (9%), IC 342426 (5%), Punjab Lal (7%), Punjab Surkh (9%) were found to be highly resistant to leaf curl virus under natural conditions. Screening with artificial inoculation confirmed that the genotypes Khandhari and Bhoot Jolokia were found to be immune and genotypes EC 391087 (11%), Punjab Lal (10%), Punjab Surkh (10%) were highly resistant to leaf curl virus. The checks Byadgi Dabbi (100%) and Byadgi Kaddi (98%) were found to be highly susceptible in both natural and artificial conditions.
