黑杨派(AIGEIROS)是杨属中较大的一派。黑杨派内种间杂种欧美杨(Populus×euramericana)的出现和大量栽植,大大推动了世界杨木的生产。要创造欧美杨优良无性系,必须有充足的杨树基因资源和完善的育种方法。我们根据意大利为代表的世界杨树育种先进国家的经验,结合我国杨树育种现状,介绍了世界黑杨派杨树基因资源;种间杂种的出现和利用;当前黑杨派杨树育种主要特点以及适宜我国黑杨派杨树遗传改良的一整套程序和方法并给予评价。
Aigeeiros is the larger genus of Populus. Populus × euramericana, an interspecific hybrid of black poplar, has appeared in large numbers and greatly promoted the poplar production in the world. To create Europe and the United States poplar clones, there must be sufficient poplar genetic resources and improve breeding methods. According to the experience of advanced poplar breeding countries in the world represented by Italy and the status quo of poplar breeding in our country, we introduced the poplar gene resources of Populus deltoides in the world; the emergence and utilization of interspecific hybrids; the main characteristics of poplar breeding poplar As well as a set of suitable procedures and methods for poplar poplar genetic improvement in China and give evaluation.
