The abstracts report condensed information from journal articles, booklets, mimeographed reports, theses, manuals and other conventional and nonconventional material, categorized into broad disciplinary fields to facilitate rapid scanning. Additionally, abstracts are author and subject indexed to enable more compre hensive consultation. When retrospective or exhaustive coverage of a topic is desired, mechanized bibliographic searches of the entire document col lection can be provided by CIAT's Documentation Center. Abstracts of all articles that match the topic of interest are provided to users who request this search service. The full text of every article abstracted by the Documentation Center is aiso available, through the photocopy service. CIAT's Documentation Center also publishes journals of analyti cal abstracts on cassava (Manihot esculenta Crantz) grown under tropical conditions, and on tropical pastures. Other CIAT publi cations dedicated to keeping users aware of research developments in their respective fields include: Pages of Contents, Cassava Newsletter, Pastos Tropicales - Boletfn Informativo, and Hojas de Frijol. iii COMPONENTS OF AN ABSTRACT Sequential number in the journal (for Year of Authors use of indexes) publication Accesion I number I 0284 (for photocopy E16751 'ALVAREZ C., E.; VANEGAS, C., G.; VICTORIA K., J.I. 1979.

Evaluations were made on 21 samples with an av. seed infection of 19.9, 5.4, and 24.4% as determined by visual analysis of abnormal symptoms on seed coats, the most probable nurber technique (MPN), and induction of symptoms on bean seedlings, resp. Results obtained with visual analysis presented a highly significant correlation coefficient .Ab.tract (0.82) with symptoms produced by X. phaseoli on bean seedlings. However, the results obtained by the HPN technique showed a high variation coefficient and low correlation coefficient with the other 2 methods. Best results were obtained by sowing bean seed samples on sterile sandy soil and later incubating 8 day-old seedlings under 1002 RH at 26"C for 48 h. ,(Author's summary) E02 Abstractor Subject and/or translator categories HOW TO USE THE INDEXES The numbers listed under each entry in the author and subject above indexes correspond to the abstract's sequential number, found each abstract within the journal. subject The last issue of the year contains cumulative author and indexes for the year.

The possibility that the characters normally utilized for the botanical description of Irhe bean cv. would permit a classification, especially regarding the comercial groups established for Brazil, was studied. The following parameters were analyzed: seedling, stem, growth habit, flowering, inflorescence, infructescence and fruits, seeds, and phenology. Variance analysis of the observed characters revealed significant differences among cv. When comparing means, no
