| Abstract: In order to enrich the tomato planting cultivars in Liupanshui city, the comparative experiment was carried out by taking 5 introduced tomato cultivars as materials in greenhouse and fi eld cultivation in 2022. The results showed that the yield of 'Shengmei' and 'Fenbeili No.9' in early spring greenhouse increased by 71% and 69% respectively compared with the control cultivar. The two cultivars had the best comprehensive performance in disease resistance, taste and commerciality, which were suitable for early spring facility cultivation in the Daqiaoba district of Liupanshui and similar ecological areas. In addition, the yield of 'Baishide 021' increased by 59% compared with the control cultivar when planted in the greenhouse, and the comprehensive performance of disease resistance and commerciality were also good, so it could be planted in appropriate
combination under the facility conditions. Under field cultivation, the yield of 'Shengmei' and 'Fenbeili No.9' increased by 232% and 170%, respectively, compared with the control cultivar, and they showed high resistance and resistance to Phytophthora infestans, which could also be planted in the open fi eld. The yield of 'Yuejia 9015'
increased by 145% compared with the control cultivar, and it showed resistance to Phytophthora infestans. 'Yuejia 9015' was the only round fruit cultivar among the tested cultivars and had the largest average number of fruits per plant, which could be used as a characteristic fruit for a small amount of planting in the open fi eld. |
