Abstract

In recent years, the Italian breeding activities in the sector of poplar cultivation for industrial purposes have led to the selection of new genotypes with high production potential, resistant to woolly aphid and to the main poplar diseases such as Venturia leaf and shoot blight, Melampsora rusts, and Marssonina leaf spots. These genotypes, known as “Greater Environmental Sustainability” clones (MSA clones), have shown promising growth and yield outcomes. This note focuses on the performance in growth and yield of a new P. ×canadensis genotype, obtained from breeding activity started in the 1990s. The ‘Tango’ clone shows very high production potential, in many cases higher than older clones used as controls. In particular, it shows faster growth after the 4th or 5th year of cultivation, resulting in higher volumes achieved by the end of the rotation period. In experimental trials, the average annual volume increment of the first 5 stem meters (representing the best wood assortments) ranged between 12.8 and 16.8 m³ ha^-1 y^-1. These remarkable yields, combined with the resistance to main diseases, make it an excellent candidate for highly sustainable poplar cultivation.
