阜新沙棘杂交类型适应性初探

The Preliminary Study Adaptability of Fuxin Seabuckthorn Hybrid Types

本文对阜新进行的“丘依斯克”和“中国丰宁”沙棘亚种间的杂交子代林的研究，选育出了7个表型良好的杂交类型。果实颜色以黄色、橘红和橘黄为主。果实百果重40～70g，成熟期在7月中、下旬至8月中旬，明显优于其母本俄罗斯引进类型。在生长势和抵御沙棘木蠹蛾危害方面表现出较强的适应性。沙棘亚种间的杂交子代，无论在果实方面，还是在生长势和抗性方面，都初步表现出较为明显的杂交优势，在阜新地区具有良好的推广前景。

The objective of this study is to select 7 good hybrid types form the offspring of Chinese seabuckthron （H. rhamnoides ssp. Sinensis） × Russian （H. rhamnoides ssp. Mongolica） . The Fruit color mainly is yellow, orange-red and an orange-based. The 100-berry-weight is 40-70g. The maturity which is form end-seven months to mid-August, is obviously later than the Russian as female parent. It showed strong adaptability in the growth potential and resisting gypsy moth. The hybrid offspring has shown the obvious advantages of hybrid in the fruit, or growth potential and resistance, which have good prospects for promotion in Fuxin region.
