Tuberose (Polyanthus tuberosa L.) is one of the most important tropical ornamental plants and cultivated for production of long lasting flowers spikes. An experiment was conducted to evaluate the performance and superiority among different tuberose cultivars over local variety under Allahabad agro- climatic conditions of Uttar Pradesh during the year 2007–2008. All total 5 numbers of cultivars (Local, Suvasini, Vaibhav, Prajwal and Shringar) were evaluated during the study period. All the cultivars differ in their growth, flowering and bulb production behavior depending upon the prevailing climatic conditions. Maximum plant height (130.54 cm) and maximum no. of bulb/Planted bulb (4.20) were recorded with cultivar Suvasini. Minimum days taken for 50% sprouting of bulbs (12.46) and minimum days taken for spike emergence (81.25) were recorded with cultivar Local. While maximum no. of leaves/plant (17.16), maximum spike length (93.00 cm), maximum no. of florets/spike (55.50), maximum length of florets/spike (6.35 cm), maximum duration of blooming spawn(38.00 days), maximum no. of bulblets/planted bulb (30.50), maximum net income (/ha 392850) and maximum B:C ratio (2.68) were recorded with cultivar Shringar. While maximum weight of bulbs (56.17 g) and diameter of bulbs (4.35 cm) were recorded with cultivar Prajwal. Among all five cultivars, cultivar Shringar was found best regarding maximum parameters.
