    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.

The state of spinach breeding, including the author's work at the Institute of Horticultural Plant Breeding, Wageningen, was reviewed.

Certain crossing combinations had a favourable effect on the yield. The possibility of combining resistance to Peronospora spinaciae (Mont.) de Bary and mosaic (Cucumus-virus 1) made the breeding of hybrid varieties still more attractive. The work required for the removal of all male and intersexual plants from the mother variety was a serious handicap.

Experiments on influencing the sex ratio and the recognition of pollen-bearing plants some time before they flower in the mother variety gave no cause for optimism. However, it was possible to breed a practically completely female first filial generation. The combination of this first filial generation as a round seeded mother variety with a prickly seeded father could bring the possibility of growing hybrid seed on a commercial scale very much nearer. Research in the field of hybrid varieties was considered to be a most important task of the research institutes.

A simple method was worked out for testing young spinach plants for resistance to downy mildew, using sheets of polythene.
