| Abstract: | In this paper, the variation of main economic characters of Hi-ppophae rhamnoides in Fengning county, Hebei Province was studied with the method of sample plot survey and statistical analysis, and, about matching character correlation with the main characters were discussed. Mea nwhile, the frequency distributions of the variations of the main characters, population features and the distribution of superior species were also analyzed in this paper.It is concluded that the population of Hippophae rhamnoides in Fengning county is a populational system of diversified phynotypes dominated with single trunk, oringe fruit and brown seed. Therefore, Hippophae rhamnoides in Fengning county is a good germplasm resource and valuable materials for improvement of the species. |
