摘要/Abstract

摘要： 为华北、西北选育抗逆性强的速生品种,我们于1957年用小叶杨为母本,钻天杨及旱柳的混合花粉(1:8)为父本进行杂交,得杂种苗。通过选择率8.05%选得杂种苗10株,形成10个无性系,其混合材料命名为群众杨,其各无性系为群众扬无性系。通过性状测定和区域化试验,说明群众杨是一个速生(木材增益达114%—690%)耐盐碱、高光效、耐旱、抗腐烂及溃疡病、材质优良的杨树新品种,适应于华北及西北栽培。通过同功酶、免疫化学等测定,它的遗传基础中参有旱柳的作用。

Abstract: In order to breed a fast-growing species with high tolerance to less favorable environment in northwest and northen regions of China In 1957, Populus simonii as female parent was crossed with mixed pollens (in 1:8) of P. pyramidalis and Salix matsudana used as male parents. Created by this combination were hybrid seedlings, from which 10 best young trees were selected to form a new cultivar named 'POPULARIS' which including 10 individual clones (CV. 35-CV. 44).The tests for identifying the characteristics of 'Popularis' shows that 'Popularis' possess the following advantages: fastgrowing, high efficiency of photosynthesis, tolerance to salinealkali soil, drought-resisting, resistance to Cytospora and Dothiorella diseases as well as fine timber quality.Its isoenzyme analysis and immunochemistry test also show that Salix plays a part in crossing produre.Regional tests have proved that 'Popularis' is suitable to grow in the Northwest, North and Northeast China.
