Abstract : The present study was done to evaluate the mango varieties for flowering behaviour in tarai region of Uttarakhand. The experiment was carried out with fourty three mango varieties in Randomized Block Design with three replications each at H.R.C., Patharchatta during the years 2012 and 2013. The varieties were found to differ significantly for the flowering traits investigated. Time of panicle emergence varied from 8 Feb in 'Duddha Peda' to 14 Mar in 'Sensation', while time of full bloom varied from 11 Mar in 'Bara Malda' to 1 April in 'Amrapali' varieties in year 2012 and 2013, respectively. The panicle length ranged from 32.85 cm in K.O.-07 to 16.82 cm in 'Safeda Lucknow', panicle breadth varied from 22.05 cm in 'Amrapali' to 8.07 cm in 'Zardalu', per cent male flowers ranged from 87.05% in 'Bada Malda' to 27.09% in 'Pulgoa Darbhanga', per cent hermaphrodite flowers varied from 72.94% in 'Pulgoa Darbhanga' to 12.95% in 'Bara Malda' and the sex ratio varied from 6.77 in 'Banarasi Betali' to 0.37 in 'Pulgoa Darbhanga'.
