半干旱地区杨树优良新品种——银新杨

A New Excellent Variety of Poplar in Semiarid Area——Populus alba × P. alba var. pyramidalis

我国有着丰富的杨树基因资源,通过对杨树优良亲本进行杂交育种,获得了具有亲本优良性状的无性系,并在生产中得到了较好的应用效果。因此,根据育种目的不同,进行不同组合的杨树杂交育种,大力推进杨树遗传基因优化,获得具有不同优良性状的新品种,不仅满足环境变化方面和用材林建设方面的需求,也是保护天然林资源的有效途径,有助于实现林业的可持续经营和发展。这些新品种优势明显,具有速生、优质、抗逆性强等特点。

There are abundant gene resources of poplar in China. Through crossbreeding of excellent parents of poplar ,clones with excellent characters of the parents have been obtained , which have been better applied in production. Therefore , according to different breeding purposes , crossbreeding of poplar with different combinations has been conducted in order to vigorously promote genetic optimization of poplar and obtain new varieties with different excellent characters , not only can meet the needs of environmental changes and timber forest construction , but also is an effective way to protect natural forest resources , and can contribute to the realization of sustainable management and development of forestry.These new varieties have obvious advantages of fast growth , high quality and strong stress resistance.
