Selection of chilli and tomato cultivars for mitigation of climate change and realization of sustainable production

Climate change is inevitable, and vegetables are sensitive to climate change. Thus, cultivars resistant to climate change are alternatives. This study was aimed at examining the adaptation capability of selected lines and varieties of tomato and chilli in farmers' lands. Five improved lines and varieties of chilli and tomato were selected. The trials were conducted using a randomized block design in upland and lowland to understand the response of selected cultivars in a new agroecosystem. There were three replications at each site. Agronomic aspects were used as performance indicators. The results showed significant differences in each site. Several improved lines of chilli showed better performance than others in high altitude. However, the performance depends on the altitude and season. Lines performed better at high altitude and could not result in the same at low altitude. This is the same case as the tomato. Some lines showed good performance in upland, but they did not show in lowland, and vice versa. Based on the finding, it is recommended that farmers are expected to select the best lines accordingly to the locations they will cultivate tomato and chilli.
