Abstract

Evaluation of millet for resistance characteristics and utilisation of elite millet germplasm in China.

Abstract

This paper reports on research conducted on resistance in foxtail millet (Setaria italica) in China to blast (Pyricularia setariae), downy mildew (Sclerospora graminicola), rust (Puccinia spp.), smut (Ustilago crameri) and stem fly (Atherigona biseta). Accessions with relatively stable resistance to diseases and with broad-spectrum resistance were found. It was shown that there was a distinct geographical distribution in the accessions that were resistant to blast and downy mildew. The results of the research on the physiological specialisation of the fungi that cause blast and downy mildew, the inheritance of rust resistance, and preliminary studies on the mechanism of resistance to stem fly are reported. The breeding of Riben 60-Day, the doubly resistant elite germplasm, and the evaluation of drought resistance and protein quality of foxtail millet are briefly described.
