| Abstract: To screen out the suitable grafting rootstocks of purple long eggplant in winter and spring in Hainan province, taking 'Yinfeng 333' as contrast, effects of 12 different grafting rootstocks on growth, yield and disease resistance of purple long eggplant were studied. The results indicated that 'Haiqiezhen No.1' 'Haiqiezhen No.5', and 'Feiqie*HZ201703' were the best grafting rootstocks among them. They were highly resistant to bacterial wilt and 15.0%, 15.8% and 15.6% higher than seedling in yield, respectlvely. Therefore, they were suitable for being used as grafting rootstocks of purple long eggplant in winter and spring in Hainan. |
