Abstract: In order to explore the effects of bee pollination on the breeding, isolation,purification and seed production of Wanzhi 16,the effect of bee pollination on the yield of Wanzhi 16 was studied. The results showed that the contribution rate of bees to the yield of sesame seeds was 5.55%, to the number of effective capsules per plant was 21.70%, to the number of grains per capsule was 5.01%, to the thousand-grain weight was 5.85%, and to the yield per plant was 3.88%,which provided a theoretical basis for the formulation of standardized seed production of Wanzhi 16.

Key words: bees pollination, Wanzhi 16 sesame, yield, contribution rate
