Abstract: Based on the flowering season data of the 57 provenance in Fuyang, Zhejiang, which was taken as one locality of national second all-distribution-area provenance tests, the male flower variation was reported. The experiment results suggested that there existed evident and stable variation in male flower trait between different seed sources, and the pollen amount of the northern zone was higher than that of the southern one. According to male flower amount and flower tree rates, 7 seed sources such as Nanzheng, Hongan, Xinxian etc. were selected as the high-yield proven ances.
