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.
