Origin	Wageningen, The Netherlands

Ulmus'Plantyn'(Anglicized form of 'Plantijn') was one of three Dutchhybrid elmsreleased by the Dorschkamp Research Institute for Forestry & Landscape Planning,Wageningen,in 1973. Derived from a crossing of the Dutch hybrids '202' (U.'Exoniensis' ×U. wallichiana)^[1]and '302' (U. minor'1' ×U. minor'28'), it was to prove of great significance in later developments.^[2]^[3]A selfed seedling was to become the first Dutch clone to prove effectively immune to disease, released in 1989 as'Columella'.'Plantyn' was also destined to be the female parent ofLutècereleased in 2002.^[4]In Italy, 'Plantyn' was used again as female parent in hybridizations with the Siberian ElmUlmus pumilaby theIstituto per la Protezione delle Piante(IPP), to create three new cultivars better adapted to theMediterranean climate(seeHybrid cultivars).

Description

'Plantyn' is a fast-growing tree, with upright branching forming a broad crown where grown in isolation. The dark-green leaves are < 10 cm long by 7 cm broad, on < 10 mmpetioles.

Pests and diseases

'Plantyn' is no more resistant toDutch elm diseasethan its Dutch contemporaries'Dodoens'and'Lobel'according to one source, rating 4 out of 5.^[5]However, research published in France by theInstitut National de la Recherche Agronomique(INRA) indicated that 'Plantyn' possesses a greater degree of disease resistance than the other two cultivars, although neither had actually been tested by the organization. Nevertheless, INRA still classified 'Plantyn' as only 'moderately resistant'.^[6]

Cultivation

Largely superseded by the later generation of cultivars highly resistant to Dutch elm disease, sales in the Netherlands declined from over 7,000 in 1979 to zero in 2004.^[7]Like its Dutch contemporaries, 'Plantyn' has proven very tolerant of sea winds.^[8]

'Plantyn' was not commercially released in the US, but was evaluated at theIowa State University(acc. no. Q 28835);^[9]however it is no longer listed (2013) in theNPGSinventory. 'Plantyn' was also included in trials[1]inCanberra,Australia, started in 1988, although it is reputed not to have thrived in that environment.
