Selection and breeding of stress-tolerant woody ornamentals for urban plantings
2013
Schmidt Gábor
Because of this geographic position, climate and soils, Hungary lends itself for selection of woody plants which tolerate environmental stresses. Selection and breeding of the woody ornamentals for extreme urban conditions started in the early 1950s at the former University of Horticulture and Food Industry (at present: the Faculty of Horticulture of Corvinus University), Budapest. The first results were 8 Sorbus, 3 Tilia and 2 other cultivars, and selected clones from Fraxinus, Cornus, Juniperus and others. In the recent 20 years, many new hardy cultivars and named clones are brought up, the most important of which are as follows: Ailanthus altissima (Mill.) Swingle cv. Purple Dragon, Acer campestre L. cv. Zentai Upright`, Celtis occidentalis L. cv. Straight Stem, Crataegus pinnatifida Bunge cv. Tahi, Hedera helix L. 9 cultivars, Platanus × hispanica Münchh. cv. Budapest, Prunus padus L. cv. Aurora, Prunus × davidopersica cv. Rubin (P. L. cv. Piroschka), Prunus tenella Batsch. cv. Pink Carpet, Pyrus nivalis Jascq. cv. Kartália, Salix matsudana Koidz. cv. Golden Spiral, Syringa josikaea J. Jacq. ex Rchb. cv. Smaragd, Tilia tomentosa Moench. cv. Zenta Silver, Tilia × euchlora K. Koch. cv. Saint Stephan.
