Introduction and testing of poplar: proposal for an exchange and testing programme
Journal Title: Лісівництво і агролісомеліорація - Year 2014, Vol 124, Issue
Abstract
Cross breeding by controlled pollinations has brought forth highly productive poplar cultivars grown on ten million ha globally. The success of poplar breeding is due to the hybridisation of differing species, which naturally would not come into contact. Examples of successful hybridisations are Populus × berolinensis Dippel, P. × canadensis Moench, P. × canescens Sm., P. × generosa A. Henry, P. × jackii Sargent, P. × wettsteinii Hämet-Ahti. Prerequisite for breeding is the exchange of germplasm among different breeding institutions. To support this as one activity of promoting poplar cultivation, the International Poplar Commission was founded in 1947 by FAO. However, important and widely distributed poplar species as Populus laurifolia have remained largely unexplored in their hybridisation potential. Fast growing and frost resistant cultivars of P. laurifolia origin like ‘Petrowskyana’, ‘Brooks’ or ‘Griffin’ raise expectations for the production of further exceptional genotypes by hybridising P. laurifolia. A proposal is made to exchange germplasm, e. g., seeds, pollens, cuttings, from natural stands and hybrid poplar clones and to use the material for cross breeding work with respect to suitability testing in a designated region of wood production.
