| 【Objective】The study was carried out to preliminarily screen out high-yield and high-quality Dading bitter gourd varieties（lines）suitable for production and cultivation in South China to meet the needs of current production and consumption.【Method】A comparative experiment was conducted on four Dading bitter gourd varieties（lines）based on their field performance, biological characteristics, agronomic traits, yields and sensory qualities.【Result】The growth potential, stress and disease resistance of four Dading bitter gourd varieties（lines）were strong. Dingfeng No. 1 was an early-maturing variety, and other three were medium-maturing varieties. The fruits of Qinglei No. 1 and Cuiding No. 1 were big, positively conical and dark green. The fruit of Guangliang No. 2 was bigger with dark green color, and positive cone was slightly longer. The fruit of Dingfeng No. 1 was bigger with light green color, and positive cone was slightly longer. Qinglei No.1 had the highest yield per unit area, which was 28 454.25 kg/hm2, followed by Cuiding No.1, Guangliang No.2 and Dingfeng No.1, with the yield per unit area of 26 473.20 kg/hm2, 25 517.70 kg/hm2 and 22 826.40 kg/hm2, respectively. Qinglei No. 1 had the highest score of sensory quality evaluation, followed by Cuiding No. 1, Guangliang No. 2 and Dingfeng No. 1.【Conclusion】The comparison of related performance results shows that Qinglei No.1 is suitable for production and cultivation in spring in South China and can be further expanded for large-scale promotion and demonstration. |
