This experiment was carried out from November 2020 to March 2021 at Horticultural Research Field, Department of Horticulture, Prayagraj, in India. The experiment was conducted in Randomized Block Design (RBD), with seven varieties of China aster and each replicated thrice. The varieties were V₁ (Bonita), V₂ (Arka Archana), V₃ (Arka Kamini), V₄ (Matsumoto), V₅ (Arka Poornima), V₆ (Phule Ganesh Pink), V₇ (Arka Shashank).
Observations were recorded on growth parameter, flower parameter, yield parameter, self-life, and economics of treatments and Subjected to statistical analysis. On the basis of results it was found that the Variety V₆ (Phule Ganesh Pink) was found to be best in Prayagraj in terms of maximum plant spread (cm²), flower diameter (cm), individual flower weight (g), self-life, flower yield/plant(g) and flower yield t/ha after 120 days.
Variety V₄ (Matsumoto) recorded minimum plant height (cm), plant spread (cm 2), number of primary branch/plant, number of leaves/plant, days of first flowering, days of 50% flowering, flower diameter(cm), stalk length(cm), number of flower/plant, flower yield/plant, flower yield t/ha whereas, maximum plant height, stalk length and number of flowers/plant was recorded in variety V₇ (Arka Shasank), the maximum number of primary branches/plant were recorded in Variety V₂ (Arka Archana), the maximum number of secondary branches, number of leaves/plant and flowering duration were recorded in variety V₅ (Arka Poornima) the maximum number of days taken for first flowering were recorded in variety V₃ (Arka Kamini).
In terms of the economics of different treatments, maximum total income, net profit, and the cost-benefit ratio were found in V₆ (Phule Ganesh Pink) followed by treatment V₂ (Arka Archana) whereas, the minimum was recorded in treatment V₄ (Matsumoto).
