First, ICRISAT mapped the genomic regions of pearl millet that control downy mildew resistance, grain production and straw yield under drought conditions.
Methods of control downy mildew included utilizing medicine and closing a greenhouse at high temperature, but were ultimately to produce resistant varieties.
These have performed as well as or better than their parent lines in terms of grain and straw yield, and possess a markedly improved resistance to downy mildew.
Climatic and seedling raising patterns are the key factors for the occurrence and widespread of rice downy mildew.
