Abstract: This paper researches the berry traits of seven F1 hybrid clones of Mongolia seabuckthorn (Hippophae rhamnoides ssp.mongolica) and Chinese seabuckthorn (H.rhamnoides ssp.sinensis) in Fuxin, Liaoning Province.According to the variance analysis on three factors of experiment areas, clones and years, eight berry traits all had extremely significant differences among clones.Experiment areas extremely or obviously influenced most of the traits except fruitbearing quantity of one infructescence and length/width ratio.The most fruit-bearing quantity of one infructescence wasn't influenced by years, while other traits were extremely done.The interaction effects of two factors gave extremely or obviously influence on most berry traits.From SNK (Student-Newman-Keuls) comparison in experiment areas, clones and years, some regularity of the berry traits can be found.The results indicated that extremely significant positive correlation existed between 100-berry-weight and berry width, extremely significant negative correlation also existed between 100-berry-weight and length/width ratio.Fruit density had extremely significant negative correlation with berry length and length/width ratio.The comprehensive arrangement of fruit quality of the hybrid clones was 3, 5, 4, 2, 6, 1, 7.Linking up fruit quality and the 100-berry-weight, the No.3 and No.2 hybrid clones were chosen as the best for fruit use.
