    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.

With few exceptions, red clover is self-incompatible. Reciprocal crosses between 30 pairs of unrelated parents sampled in a population, were all compatible. Three full-sib F2's from one of these crosses showed, in 8 x 8 diallel crosses, 2, 2 and 4 incompatibility groups, and an F5 showed, in a 15 x 15 diallel cross, 2 incompatibility groups. The data were explained by a (large) series of S alleles, as proposed by East for Nicotiana and by Filzer for Veronica.

In a number of progenies, male-sterility (degenerate anthers) was found and a recessive factor was identified.

Seed-coat colour (yellow versus violet) was polymerically controlled (up to 5 cumulative factors), complicated by environmental and within-plant variation. In certain progenies a factor for violet (v) and an intensifier (X) could be identified. The quality of yellow and of violet was controlled by C-c and by R-r, respectively.

Flower colour was determined by the factor G for anthocyanin production and by B-b for purple or pink, along with at least 3 intensifiers of purple.

Two chlorophyll abnormalities depended on recessive factors (chlorina and albina) and one was plasmatically inherited (albomaculata). Two types of dwarfs (nanella and nana) were single recessives.
