Abstract

Ten chili genotypes of germplasm collection had been evaluated in limited watering condition. The purpose of this research was to obtain genetic material that can be used in breeding program. The study was conducted from February to December 2017 at Indonesian Vegetable Research Institute, Lembang (1,250 m sal). The research used a factorial design with three replications. The first factor was ten chili genotypes and the second factor was the frequency of watering (F0 = daily watering- F1 = watering with interval two days- F2 = watering with interval four days- F3 = watering with interval six days). The seedlings were planted in plastic pots with media soil and sand (1: 2), then be applied the treatments. The population number of each genotype per treatment was 15 plants/replication. The results showed that genotype ANS had better tolerance in limited watering condition compared to other genotypes by some mechanisms, i.e the smallest change in total amount of chlorophyll content but increase in proline content, and reduction in leaf area and stomata number. These result could determine a good strategy for each genotype to be improved as a new variety that tolerance in limited watering condition.
