半干旱区生态经济型沙棘育种研究——“蒙×中”沙棘杂交子代优良单株选择及适应性分析

Study on Seabuckthorn Breeding of Eco-economic Type in Semi-arid Areas: Prior Single Plant Selection from Hybrid F_1 of Mongolian and Chinese Subspecies and Its Adaptability

在半干旱区的内蒙古鄂尔多斯市东胜区九成宫基地,从蒙古沙棘亚种和中国沙棘亚种杂交子代雌株群体中选择出3株杂种优势显著的优良单株。它们兼有母本和父本的优良性状:生长适应性强,营养生长和生殖生长明显超过双亲,果实产量高,营养品质好,棘刺较少。以杂雌新品系营造半干旱区生态经济型沙棘林,会获得很高的经济效益和生态效益。

Three prior single plants are selected from the female community of hybrid F1 from Hippophae rhamnoides ssp. mongolica and Hippophae rhamnoides ssp. sinensis in the semi-arid areas of Jiuchenggong Base located in Dongshen, Erdos, Inner Mongolia. The three F1 have good charecteristics of both parents, such as strong adaptability, higher growth index and yield, better fruits quality, and less thorn than the parents. The application of the three new forms for eco-economic type of seabuckthorn in simi-arid areas will produce good economic and ecologic benefits.
