This study aimed to investigate the difference in yield, nutrient uptake, and fruit quality among the major pepper cultivars in Chongqing, and to identify suitable, high-yielding cultivars for this region. The main pepper cultivars in Chongqing were taken as study object and classified into three categories based on fruit type: sweet pepper, long pepper, and chaotian pepper. The yield, nutrient uptake, and fruit quality indices were measured, and a comprehensive evaluation was conducted using principal component analysis and membership function method. The results showed that: 1) Significant differences in various indices were observed among the three fruit types (P<0.05). Vegetable pepper exhibited 19.4%-34.7% higher average yield than the other types, and its average accumulation of nitrogen, phosphorus, and potassium in fruits was 7.9%-27.4% higher than that of the other types. 2) Significant differences in yield and nutrient uptake existed among pepper varieties (P<0.05). ‘Yujiao No. 13’ showed a yield increase of 6.8%-142.7% compared with other varieties. ‘Meila No. 1’ showed a relatively higher response to nitrogen, while ‘Baopi Zaoyou F1’ showed a relatively higher response to potassium. 3) Quality indices varied with maturity stage. From the green-ripe to red-ripe stage, vitamin C and nitrate contents showed an overall increasing trend. At the green-ripe stage, ‘Bopi 127’ had the lowest nitrate content (11.9 mg/kg), while at the red-ripe stage, ‘Lvyangle L9’ exhibited the highest vitamin C accumulation (234.8 mg/100 g), and ‘Yujiao No. 13’ reached a peak soluble sugar content of 28.8 mg/g. In conclusion, vegetable pepper ‘Jiubiji No. 9’, strip pepper ‘Lvyangle L9’, and pod pepper ‘Yanjiao 465’ demonstrated clear quality advantages and are recommended as main cultivars for introduction and promotion in Chongqing and ecologically similar regions. This study provides a theoretical basis for improving yield and quality in the pepper industry in Chongqing.
