the Symposium on Wheats for More Tropical Environments - cimmyt

77Variety improvement must also becombined with agronomic research.Agronomists in sou<strong>the</strong>rn China havebeen working on <strong>the</strong> populationstructure of high yielding wheat,including yield components andcultivation techniques. Thesetechnologies have led to better yields ofwheat after rice in <strong>the</strong> last ten years,and have played an active role inincreased wheat production. Agronomicresearch must be fur<strong>the</strong>r stressed inorder to increase <strong>the</strong> production,quality and economic benefit of wheatin <strong>the</strong> region.References1.
