A comprehensive study of genetic gains resulting from long term breeding work on improved hybrids and open-pollinated varieties (OPVs) in eastern and southern Africa shows that with appropriate funding, maize yields can continue to increase in extreme heat and drought conditions.
The world faces the challenge of growing more maize, responsibly and sustainably. Development of high yielding maize varieties resistant to different biotic and abiotic stresses quickly and efficiently is the need of the hour. Use of new tools and technologies is critical in achieving rapid progress in development of improved maize germplasm.
