Significant progress has been made in developing highly effective and reliable laboratory/greenhouse and field screening techniques and in using them to identify resistance, and to develop cultivars resistant to downy mildew (Sclerospora graminicola). Using these techniques, 4771 accessions of pearl millet, 50 accessions of intermediate weedy forms, and 534 accessions of wild relatives, originating from 40 countries, have been screened in India and/or western Africa, and a large number of resistant sources identified. More than 20 breeding products have been developed and released for cultivation in India and Africa. Similar progress in developing cultivars resistant to rust (Puccinia spp.) has been made. This bulletin describes allthe currently known screening techniques and provides relevant information on important sources of resistance to these two diseases. It is expected to be useful to breeders and pathologists involved in improving pearl millet for genetic resistance to these two important diseases.

Very significant advances have been made in downy mildew research since the last major text on these oomycete fungi and the diseases they cause was published in 1981. The emphasis in this new volume is on evolution and phylogeny, control with chemicals including those that manipulate host plant defences, mechanisms of resistance, virulence and the gene pool of wild relatives of crop plants. Additionally, definitive lists of binomials and authorities provide a key reference source. The book is relevant to anyone with an interest in these unique biotrophic pathogens, either in their own right as causes of damaging diseases or as model systems for research on host-pathogen interactions. It should be read by: students, teachers and researchers in academic and research institutes; research and development personnel in the agrochemical industries; agricultural and horticultural advisers, and other extension workers.

This book develops a new interpretation of Aristotle's Metaphysics. By exploring the significance of the long ignored distinction between being with regard to categories and being with regard to potentiality and actuality, the author presents that Aristotle's science of being has two distinct aspects: an investigation of the basic constituents of reality in terms of categories, predication, and definition, and an investigation which deals with change, process, and order of the world.
