First Results of Arborescent Willow Improvement by Seifing, Back Cross and Transgression     pdf     HR     EN 163
Summary: To meet the requirements of biomass production in short rotations, the White Willow (Salix alba L.) has been crossed with the Chinese Willow (Salix matsudana Koidz.). For the first time the improvement methods of selfing, back cross and transgression have been used.

Crossing of the Chinese, tortuous Willow (Salix matsudana f tortuosa Koidz.) with the autochtonous White Willow produced interspecific hybrids which in higher percentage were monoecious. By selfing the hybrids 25 plants have been raised. Due to their poor vitality, the only one survived plant was male and was used to obtain pollen for hybridization.

Back crosses of F´ generation hybrids were made on the Chinese Willow, while for the production of F2 generation hybrids, the genetically divergent (New Zealand, Croatia) hybrids Salix matsudana x Salix alba were used.

Improvement by hybridization using selfing, back cross and transgression proved that on the basis of transgression plus variants can be produced with respect to biomass. Using a mentioned improvement methods, a large number of minus variants also became differentiated in the progeny. Phenotypically, in addition to dwarfness size, they show the characteristics which occured as the result of the appearance of atavisms (such as small narrow leaves, small stem and branchlets covered with periderm, etc.) thus being suitable for arborescent Willow evolution studies.

Cloning plus variant it was possible, in the produced families, to make selection of new genotypes of Arborescent Willows that will be suitable for biomass production in short rotations. Morphologically aberrant minus variants can be used in horticulture.
Key words: Arborescent Willows; biomass; improvement by selfing; back cross and transgression
