    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

Cold resistance appeared to be so complicated and variable, that a clear insight could be obtained only when important factors such as degree of vernalization, stages of growth and development, and hardening were considered in the experiments. For various reasons, breeders are more and more obliged to use extremely varied material in their programmes, such as of breeding for disease resistance.

In 1951 the Foundation for Agricultural Plant Breeding at Wageningen had a refrigerator and hardening equipment installed to provide private breeders with cold-resistant material and to test their new lines for this character. This gave the author the opportunity to study winter-hardiness.

It was possible to develop winter wheat varieties with sufficient winter- hardiness, slight need of vernalization and rapid spring development. Varieties of winter barley could be developed with a better winter-hardiness.

The method recommended by Hoffmann of vernalizing the seed before sowing in autumn to test and select for winter-hardiness was highly practicable. Trials on date of sowing in autumn involving seed vernalization and lengthening of the day were a valuable aid to research on cold resistance.
