Abstract: 【Objective】Screen out daylily cultivars suiting for planting in Northern Jiangsu Province.【Methods】Twenty-five domestic common varieties were introduced for field cultivation,and the main botanical characters and flower bud quality were investigated and analyzed.【Results】The flowering time of Sanyuehua,Datonghuanghua and C1 were 16,8 and 7 days earlier than that of the control,and the flower bud weight was 4.07,3.40 and 4.27 g,respectively.The yield of Datonghuanghua was significantly higher than that of the control(P<0.05),but the yield of C1 was not significantly different with that of the control(P>0.05).The contents of soluble sugar,free amino acid,VC and flavonoids in Sanyuehua were significantly higher than those in the control(P<0.05),while the colchicine content was significantly lower(P<0.05).The contents of soluble sugar and polyphenols in Datonghuanghua were significantly higher than those of the control(P<0.05),and the contents of polyphenols,VC and flavonoids of C1 were significantly higher than those of the control(P<0.05),and their adaptability and resistance were better. The flowering period of Qiezihua and Changzuizihua was similar to that of the control,the number of flower buds and yield were significantly higher than those of the control(P<0.05),the flavonoids content of Changzuizihua was significantly higher than that of the control(P<0.05),and the protein content of Qiezihua was significantly higher than that of the control(P<0.05). Their content of other nutritional quality were not significantly different with that of the control(P>0.05),their adaptability and resistance were better.【Conclusion】Sanyuehua,Datonghuanghua and C1 had better performance in early maturity,flower bud weight,quality,and resistance,which were suitable for early production in Plastic Greenhouse. Qiezihua and Changzuizihua had better performance in yield,quality,and resistance,which were more suitable for drying and quick freezing production.
