Abstract
Poplar is one of the established exotic crop of forestry as well as agro-forestry in Tarai and adjoining areas of U.P. It needs further improvement in production. One of the important methods of improving poplar is through interspecific hybridization. This communication deliberates the results of interspecific crosses among different cultivars of American Poplar (Populus deltoids), Indian Poplar (P. ciliata), Chinese Poplar (P. yunnanensis) and Euramarican Poplar (P. x euramaricana robusta) including results of reciprocal and back cross. Some of the significant findings on heterosis, maternal inheritance, disease resistance, etc., have been discussed. Few very promising hybrid clones selected were tested in nursery and have been carried forward for field testing. Initial performance of these selected hybrids have ascertained the possibility of qualitative and quantitative improvement of Poplar.
