Screening Techniques and Sources of Resistance to Downy Mildew and Rust in Pearl Millet


Book Description

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.

Downy Mildew in Pearl Millet


Book Description

Downy mildew caused by Sclerospora graminicola is a destructive disease affecting both vegetative and floral parts of the crop, causing huge monetary losses. It is prevalent in many parts of India and several African nations. Biochemical markers provides information of genetic and metabolic factors governing resistance. The content of this book focuses on finding out appropriate biochemical markers useful for screening downy mildew resistance in pearl millet. Different parameters such as isozymes, protein profilling (SDS-PAGE), molecular marker (RAPD), quality parameters, few stress metabolites and histochemical analysis have been analyzed. This book can be of use to the plant biochemists, pathologists, breeders and to the scientific community at large.
