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.
The Development Economics Group at Wageningen University (WUR, the Netherlands), the International Maize and Wheat Improvement Centre (CIMMYT, Mexico) and the International Food Policy Research Institute (IFPRI, USA) are searching for
three PhD researchers
Marker-assisted recurrent selection (MARS) is helping maize breeders develop higher yielding and drought-tolerant improved varieties faster than ever before, according to a recent study from scientists at the International Maize and Wheat Improvement Center(CIMMYT).
“With conventional breeding, it often takes up to 7-8 years for varieties to reach farmers,” said Yoseph Beyene, a CIMMYT maize breeder working with the CGIAR Research Program on Maize (MAIZE) and one of the authors of the study. “With MARS, those varieties take only 5 years to reach farmers, and display greater genetic gain, even under drought conditions”
Smallholder farmers in South Africa can now access and grow new maize varieties with transgenic resistance to stem borers, the most damaging insect pest of maize.
Partners in Water Efficient Maize for Africa (WEMA) – a public-private crop breeding initiative that helps farmers manage the risk of drought and stem borers infestation in Africa –developed the genetically modified maize seed branded as “TELA” that has been released and licensed to seed companies in South Africa at royalty-free to sell to farmers at an affordable cost.
TELA – derived from a Latin word Tutela meaning “protection” – contains a gene from Bacillus thurigiensis (Bt) that helps the maize to resist damage from major stem borers to give farmers better yield. Five seed companies – Capstone, Jermat, Monsanto, SeedCo and Klein Karoo – are marketing the seed to smallholders.
