Abstract: In order to screen excellent hybrid germplasm resources of seabuckthorn,this experiment used a total of thirteen female seabuckthorn materials from the hybrid F₁ generation,its parents,and the control variety as the test materials.By investigating and comparing relevant indicators such as phenology,growth traits,growth rate,and fruit traits,a membership function equation was established to comprehensively evaluate ten hybrid F₁ generation materials.The experimental results showed that,the fruit maturity period of hybrid F₁generation was from August 13^th to 15^th,which was between Chinese seabuckthorn and Mongolian seabuckthorn.The average plant height of the test materials was 284.68 cm,the average crown width was 205.85 cm,and the average ground diameter was 5.47 cm.The growth traits of the hybrid seabuckthorn between China and Mongolia were significantly higher than those of the control varieties,namely female seabuckthorn and Chuyi seabuckthorn.They had the characteristics of strong tree power and fast growth rate.The average weight of fruit per hundred fruits was 30.33 g,and the weight of Russian large fruit seabuckthorn variety Chuyi per hundred fruits was significantly higher than other test materials.The lowest weight of female seabuckthorn per hundred fruits was 11.21 g.The average yield per plant was 8.28 kg,which was higher than that of the female parent Chuyi seabuckthorn and the control variety female of Chinese seabuckthorn.Among them,the Zhongmengza female 6 material had the highest yield per plant of 12.25 kg,while the female of Chinese seabuckthorn material had the lowest yield per plant of 2.43 kg.Through comprehensive evaluation,the E values of the two experimental materials,Zhongmengza female 6 and Zhongmengza female 10,were higher than those of other materials,and can be used as germplasm resources for preservation and promotion of mid maturity hybrid seabuckthorn cultivation.
