Fifteen carnation varieties viz., Baltico, Charment, Dark Rendeous, Dover, Farida, Firato, Kazhuca, Madras, Malga, Master, Pink Diamante, Tabor, Tasman, Tiker and Varna were selected for evaluation. The cuttings with well developed roots were planted at 25 cm x25 cm spacing in the month of December, 2008 and the observations on vegetative and floral characters were recorded. There were significant variation in plant growth and flower quality parameters of different varieties of carnation. In field conditions, maximum plant height (57.27 cm), number of leaves (174.53), and number of flower per plant were recorded in variety Varna whereas, in polyhouse conditions, maximum plant height (86.27 cm), number of leaves (196.93) and number of flower per plant was recorded in variety Charment. Dark Rendeous, Baltico, Madras, Firato and Tasman were found to take minimum number of days for bud initiation under field and polyhouse conditions. In field conditions, the longest primary flower stalk length was observed in variety Varna (54.27cm) followed by Malga (50.00cm) and secondary flower stalk length in variety Tabor (25.00cm) which was significantly higher over other varieties. Variety Varna produced primary flower of maximum diameter (6.10cm) followed by varieties Baltico (6.07cm) and Malga (6.03cm). The diameter of secondary flower was maximum in Baltico (6.02cm). In polyhouse conditions, the significantly longest primary flower stalk length was observed in variety Charment (82.13cm) followed by Malga (77.67cm), Dover (75.67cm) and Varna (75.33cm) and secondary stalk length in Dark Rendeous (29.00 cm). The maximum diameter of primary flower was recorded in Charment (6.78 cm) followed by Malga (6.73cm) whereas, the secondary flower diameter was maximum in Malga (6.34cm) which were significantly superior over other varieties. Maximum calyx splitting was recorded in variety Baltico under field conditions while under polyhouse conditions, maximum calyx splitting was also recorded in variety Baltico.enDevelopmental stages, Planting, Land resources, Budding, Harvesting, Biological development, Productivity, Yields, Environmental factors, Research methodsIntroduction and screening of carnation (Dianthus caryophyllus L.) varieties under field and polyhouse conditionsThesis
