Abstract ：In recent years，Hemerocallis fulva has been widely introduced and cultivated across China due to its potential for garden use.However，it has not previously been introduced in the Yangling region.To screen out daylilyvarieties suitable forcultivation in Yangling and to support the large-scale introduction of Hemerocallis fulva，2O varieties were systematically evaluated in terms of phenology，morphological traits，and growth adaptability.Fifteen evaluation indicators，including plant height，crown width，and number of leaves，were selected based on field observations，a literaturereview，and expert consultation.A comprehensiveevaluation system was established，and the Analytic Hierarchy Process （AHP）was applied to asses 2O Hemerocalls fulva varieties.The results showed that allintroduced varieties were able to grow and develop normall. However，variations were observed in phenological stages：buding occurred in early March，leaf expansion occurred in mid - March，flowering occurred from May to August，and leaf yellowing occurred in early November. Significant diffrences were also found in morphological traits and growth adaptability among the varieties.According to the AHP results，resistance to pests and diseases，the duration of the flowering period，and heat tolerance were the most critical factors in the comprehensive evaluation.Additional important factors included growth vigor，flowering time，number of flowers per stalk，and flower color.Based on their comprehensive evaluation scores，the 20 Hemerocalis fulva varieties were clasified into three performance categories.In conclusion，among the tested varieties，‘Persian Bazaar，’‘Miss Amelia，’and‘Woman’s Heart’（Grade I） demonstrated superior performance and are suitable for large-scale cultivation in Yangling.‘Pardon Me’and nine other varieties showed good overallperformance and have potential for selective introduction and promotion.In contrast，‘Siloam Tom Thumb’and eight other varieties exhibited poor performance and are not recommended for cultivation in this region.
