Abstract: The relationship between the main agronomic traits, yield and quality of 50 hops germplasms was analyzed to determine the agronomic traits, which could be used to select the high yield and high quality hops. The results showed that both agronomic traits and quality indicators existed large variation, which could create conditions for screening of excellent resources. There was some correlation between agronomic traits and quality indexes. There was a significant positive correlation between the spike thick (R2=0.293), the single flower weight (R2=0.288) and the ratio of fresh weight and dry weight. There was also a significant positive correlation between spike length, the ratio of fresh weight and dry weight and the content of xanthohumol, and the contribution to content of xanthohumol of the fresh weight and dry fresh ratio was higher than that of spikes length. However, the six main agronomic traits had no significant correlation with content of alpha-acid. The results indicated that the hops germplasms with high ratio of fresh and dry weight, yield, xanthohumol content and medicinal value could be selected by agronomic traits such as spike length and spike thick, while which could not be screening indicators for the germplasms with high alpha-acid content.
