Evaluating the Impact of Climate Change on Wilt Incidence in Chilli(Capsicum annuum L.) in Temperate Ecologies: Mitigation Strategies and Adaptation Approaches

Chilli holds significant importance among the various vegetables cultivated in temperate
regions, particularly in the Kashmir Valley. Climate change has notably increased the
frequency and severity of wilt disease in chilli, leading to crop losses ranging from 45 to 60
percent in the Kashmir Valley alone [1],[2] by altering pathogen dynamics. Rising
temperatures, changing rainfall patterns, elevated CO2 levels, and extreme weather events all
contribute to the evolving landscape of wilt diseases. Tackling these challenges requires a
comprehensive approach, including the development of resistant crop varieties, effective
disease management strategies, and staying updated on the latest research and technological
advancements. By adopting proactive measures, it is possible to reduce the impact of climate
change on wilt diseases and ensure the continued productivity and sustainability of
agriculture in temperate regions. In this context, the current study focuses on the
identification, isolation, and utilization of wilt-resistant lines/hybrids. The experimental
material consisted of eighty genotypes including sixty-six crosses, twelve parents and two
checks. The experimental material was subjected to screening under both field and in vitro
conditions against wilt disease. The results revealed that twelve chilli genotypes showed
highly resistant reaction against wilt disease and twenty-six genotypes showed resistant
reaction. The rest of the genotypes were moderately resistant, susceptible or highly
susceptible. Thus the genotypes showing highly resistant/ resistant reaction to this devastating
disease can be further evaluated and released among farmers, so that farmers can use these
genotypes and prevent their crop losses posed by climate change.
