Abstract : Anther dehiscence, pollen viability and pollen germination on agar medium were determined in 3 mango cultivars with different fruit set characters. The studied cultivars were Khiew Sawoey which naturally had low fruit set, Nam Dok Mai with moderate fruit set and Choke Anan with high fruit set. The results showed that Choke Anan had the highest anther dehiscence of 74.46% whereas Khiew Sawoey and Nam Dok Mai showed anther dehiscence of only 14.95 and 20.06%, respectively. All cultivars had high pollen viability (81.33%-91.29%) with germination of 24.1-32.51%. Poorly dehisced anthers is a factor causing low fruit set in Nam Dok Mai and Khiew Sawoey.
