Objective:To provide theoretical basis for further development and utilization of high-qual-ity seabuckthorn resources,the comprehensive quality differences of 5 seabuckthorn germplasm re-sources were analyzed. Methods:The Mongolian and Chinese hybrid seabuckthorn clones (QQHE-19-02,QQHE-19-04,QQHE-19-06 and QQHE-19-08) were taken as the research objects,and 'Shenqiuhong' varieties were taken as the control. From the aspects of plant growth,fruit shape,fruit color and fruit quality,variation analysis,correlation analysis,linear regression analysis and grey cor-relation analysis were carried out. The comprehensive score of fruit quality was calculated and ranked. Results:(1) The tree growth of QQHE-19-02 was weak. The plant height was 213.33 cm and the crown width was 131.67 cm,which was significantly lower than the other 4 seabuckthorn germplasm resourc-es. There was no obvious different between QQHE-19-04,QQHE-19-06,QQHE-19-08 and 'Shen-qiuhong'.(2) The fruit shapes of 5 seabuckthorn resources were difference. The fruits of QQHE-19-06 were basically round,while those of QQHE-19-02,QQHE-19-04 and QQHE-19-08 were oblong,and 'Shenqiuhong' were actually cylindrical. (3)The variation coefficients of fruit traits of 5 seabuck-thorn germplasm resources ranged from 8.17％ to 32.14％. The coefficient of variation of fruit intrinsic quality index ranged from 8.85％ to 32.14％,indicating that the diversity of fruit quality traits was rela-tively rich. (4) The longitudinal and transverse diameters of seabuckthorn fruits had significant effects on fruit weight (P<0.05). Fruit quality was closely related to sugar and acid content,while vitamin E was independent. Conclusion:5 seabuckthorn resources could grow normally in the test site,and the ecological adaptability was strong. The performance of the 5 seabuckthorn resources from good to bad was as follows:QQHE-19-06>QQHE-19-08>QQHE-19-04>Shenqiuhong>QQHE-19-02.
