Identifying Sources of Resistance to Grain Molds and Mycotoxins in Pearl Millet


Screen, identify and develop genotypes of pearl millet with resistance to seed and grain molds to improve stability of production and food safety.

More information

APPROACH: 1) Collect and evaluate diverse pearl millets to identify grain mold resistance, 2) evaluate general and specific combining ability and heritability of resistance to grain mold development in field and laboratory studies, and 3) quantify changes in nutritional composition (protein, carbohydrate, and fat) and associated mycotoxin contamination in molded grain.

<P>PROGRESS: 2005/10 TO 2006/09<BR>
Progress Report 4d Progress report. This report serves to document research conducted under a reimbursable agreement between ARS and USDA-FAS. Additional details of research can be found in the report for the parent CRIS 6602-21410-004-00D Genetic enhancement of warm-season grass species for forage and alternative uses. This research is being conducted to identify sources of grain mold resistance in pearl millet. One hundred landraces accessions were collected in diverse locations in Ghana. These accessions were increased in quarantine in the U.S. for evaluation in the 2006 field season. The U. S. pearl millet collection currently has six pearl millet accessions from this country., with the latest acquisition in 1968. Additional potential sources of grain mold resistance have been requested from advanced breeding lines of the pearl millet project of the International Crops Research Institute of the Semi-Arid Tropics.
