| 【Objective】The study was performed to enrich the germplasm resources and germplasm creation of lily in order to lay a foundation for screening out high-quality germplasm resources and the creation of lily in cold area of Liupanshan Mountain.【Method】Field plot experiment was used to analyze the growth rules, photosynthetic characteristics, flower and bulb morphological characteristics and yield components of six lily germplasm materials, and DPS11.0 statistical software was used for comparative analysis.【Result】The plants of lily grew extremely slowly in the early stage, entered a rapid growth stage from the gestation stage to the squaring stage and reached the peak growth period, and then grew slowly, with an S-shaped curve and a slow-fast-slow growth law. SB5 and SB2 of lily germplasm resources with outstanding performance were screened out, and the annual lily bulb yields were 886.87 kg and 553.96 kg per 667 m2 respectively, with significant yield difference.【Conclusion】The lily germplasm resources SB5 and SB2 with excellent yield and ornamental value suitable for planting in the cold area of Liupanshan Mountain were screened out. |
