Fifteen different male palms were selected from wild grooves for studying their floral characteristics and their effect on fruit yield of Dhakki. The male palms differed significantly in days to spathe opening. The M6 took significantly maximum time for spathe opening while the least time was noticed in Mi3. The significantly longest spathes were found in M10 whereas the M12 possessed spathes of maximum width. The greatest flower spike length was observed in M8. Male palms did not differ significantly in number of strands as well as number of flowers per spathe. The maximum number of flowers per spathe was recorded in M11 while minimum number of flower per spathe was found in M2. Significantly maximum number of flowers per strand was recorded in M6, the M5 possessed significantly highest viability of 95.67%. Pollination with different males on Dhakki females resulted significant variation in fruit set. The highest fruit set occurred due to M5 pollens. Fruit yield per bunch was significantly affected due to different male palms. The highest fruit yield per bunch was obtained by fertilization of M5 pollens.
