    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.

Various strains of bean common mosaic virus (BCMV) occur in susceptible cultivars of bean. To compare these strains, a standard procedure for identification and a set of differential cultivars were established. The differentials are representatives of 11 resistance groups, determined by testing of about 450 bean cultivars with 8 to 10 strains. The virus strains and isolates were classified into 10 pathogenicity groups and subgroups, so that 10 strains were distinguished and the others considered as isolates of those strains.

Twelve differentials were intercrossed and their F 1 and F 2 tested with most of the strains for genetical analysis of resistance in bean. Seven genes were distinguished: a necrosis gene I , already known from the literature, 5 strain-specific resistance genes be-1, be-1 2, bc-2, bc-2 2 and bc-3, and a strain-unspecific gene bc-u, complementary to the strain-specific ones. Genes be-1 and be-1 2 were allelic, as were bc-2 and bc-2 2. The 5 loci segregated independently or nearly so. The 4 strain-specific genes bc-1 to bc-2 2 had a gene-for-gene relationship with 4 pathogenicity genes, likely to be present in the virus strains. Gene bc-3 had not been overcome by a corresponding pathogenicity gene. Two bean genotypes were developed with resistance to all known strains. Some implications for resistance breeding are discussed.
