    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.

Progeny testing of timothy was studied. Testing in mixture was carried out in two ways: drilling progenies in rows alternating with close (15 cm) lines of a competitive species and as spaced plants in the sward of a competitor (mostly perennial ryegrass). A positive but not always high correlation was found between testing in mixture and in monoculture. It was concluded that grasses should be tested in a dense crop, as the order of the families is largely governed by competitive or non-competitive spacing. Interspecific competition will have an influence under unfavourable conditions. Root competition was more important than shoot competition. For dry matter yield and heading date, the effect of general combining ability was the most important part of genetic variance. The estimated heritability for dry matter yield was higher for testing in competition than in monoculture. The implications for breeding are discussed.
