Abstract: In order to guide the breeding of new grain-type soybean varieties in Hubei Province, this experiment analyzed the experimental data of 45 grain-type soybean varieties approved by Hubei Province from 1987 to 2022 to study the changes and relationships of the certified varieties among the important agronomic traits, yield, quality traits and disease resistance. The results showed that there was less variation in quality traits and greater variation in yield and related agronomic traits in the genetic variation of certified varieties. The 8 traits of certified variety, plant height, nodes on main stem, effective branch number, pod number per plant, seed weight per plant, 100-seed weight, yield and fat content, showed an upward trend while the whole growth period and protein content showed a downward trend with the growth of years, and the change trend of total protein and fat content was not obvious. The resistance of grain-type soybean varieties approved by Hubei Province from 2015 to 2022 to soybean mosaic virus（SMV） is mainly intermediate type, so the selection of SMV resistance still need to be strengthened in the future breeding process. The correlation analysis showed that the yield was significantly positively correlated with the grain weight per plant（r=0.277） which was significantly positively correlated with the number of effective branches and the number of pods per plant（r=0.554, 0.646）. Therefore, in the future breeding of grain-type soybean varieties in Hubei Province, attention should be paid to the coordinated improvement of the number of effective branches, the number of pods per plant and the grain weight per plant in order to increase yield.
