First, ICRISAT mapped the genomic regions of pearl millet that control downy mildew resistance, grain production and straw yield under drought conditions.
首先，国际半干旱热带作物研究所绘制了珍珠谷子的基因区，这些谷子可控制干旱条件下的霜霉病抗性、谷物产量和产草量。
Several powdery mildew resistance genes derived from wild emmer accessions have been mapped on the short and long arms of chromosome 2B by SSR marker.
利用抗病分离群体，我们在野生二粒小麦2B染色体上发现了多个抗白粉病基因，并利用SSR分子标记进行了定位。
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.
就谷物和产草量而言，新品种性能相当于或优于其母本品系，而且对霜霉病的抗性显著增强。
