沙兰杨是辽宁省当前杨树中生长最快的品种,现已进行了大面积推广。但是沙兰杨却存在于形不直,易形成卡脖枝的不足之处,栽培推广受到一定影响。为了选育生长速度超过沙兰杨,干形良好、材质优良的新品种,1982年利用美洲黑杨部分栽培品种与欧美杨一些栽培品种和上述两类栽培品种之间进行了7个杂交组合的人工基因重组,F_1代苗木经4年来的研究,获得了较好的效果,同时也产生了较明显的杂种优势。
Salmonella poplar is the fastest-growing poplar species in Liaoning Province and has been widely popularized. However, the existence of Shalan Yang in the shape is not straight, easy to form branches of card neck inadequacies, cultivation and promotion are subject to a certain extent. In order to breed new varieties growing faster than Salmone, good stem shape and good quality, in 1982, seven hybrid combinations were made between some cultivars of Populus deltoids and some cultivars of Populus euphratica and the two cultivars Artificial genetic recombination, F_1 seedlings after 4 years of study, obtained good results, but also had a more obvious heterosis.
