Abstract/Description
The CGIAR Research Program on Wheat (WHEAT) bread wheat breeding program at CIMMYT delivered significant genetic gains to National Agricultural Research System (NARS) partners by developing high-yielding, disease-resistant wheat germplasm. Analysis of historical data showed grain yield gains of 46.6 (irrigated), 57.7 (drought), 65.1 (high rainfall) kg/ha/yea, or 0.5-1% p.a. On-station trials of selected varieties/germplasm delivered similar estimates. These genetic gains in grain yield impact an estimated 61 million hectares of the 215 million hectares of the global wheat area.
