意大利杨树育种学家当前主要工作是放在黑杨派树木的遗传改良,积极选育适宜在中、北部平原地区生长的欧美杨无性系。同时适当搞些适宜在丘陵和山地生长的、用黑杨派与青杨派的派间杂交及青杨派、白杨派派内杂交而创造的新无性系。G.雅科梅蒂教授曾在1929年杂交出一批欧美杨杂种。二次世界大战后,皮卡罗(piccarolo) 教授从这批杂种苗中选育出世界著名的I-214、I-262、I-455、I-488等欧美杨新无性系而代替原来的I-154。其中以I-214最为优良,并且迅速被世界有关国家引种。目前,意大利杨树人工林为15万公顷,占全国森林总面积2.5%,其中I-214栽植最多,占意大利杨树人工林的72%。I-214具有抗黑
Poplar breeders in Italy are currently working mainly on genetic improvement of black poplar trees and actively breeding European and American poplar clones suitable for growing in the central and northern plains. At the same time appropriate to engage in some suitable for growth in the hills and mountains, with the Black Poplar and Green Young faction cross-breeder and Green Young faction, Poplar pie and create new clones. G. Professor Jacomethi had in 1929 a hybrid of European and American poplar hybrids. After the Second World War, Professor Piccarolo bred young clones of New World Poplars such as I-214, I-262, I-455 and I-488 in the world from these hybrid seedlings instead of the original I-154. One of the most excellent I-214, and quickly introduced by the countries in the world. At present, the poplar plantation in Italy is 150,000 hectares, accounting for 2.5% of the total forest area in the country, of which I-214 is the most planted, accounting for 72% of the poplar plantation in Italy. I-214 has anti-black
