“Bazooka” maize makes a bang in Uganda

Unprecedented droughts have hit Uganda’s farmers hard in recent years, affecting household income and food security by drastically cutting maize yields, a staple crop in the country. In 2016, at least 1.3 million people in Uganda faced hunger and urgently needed food aid after a dry spell decimated harvests, leaving some with less than one meal per day. When MLN, a maize disease with the ability to cause extreme or complete crop loss in maize, arrived in Uganda in 2013, farmers needed a variety that could cope.

Fall Armyworm devastates crops in sub-Saharan Africa: A quick and coordinated regional response is required

The recent appearance of the fall armyworm, an insect-pest that causes damage to more than 80 crop species in 14 countries in sub-Saharan Africa, poses a serious challenge and significant risk to the region’s food security.

In a recent interview, Dr B.M. Prasanna, director of the Global Maize Program, CIMMYT and the CGIAR Research Program on MAIZE, who is working at the forefront of CGIAR’s response, highlights the potential impact of the pest and how CGIAR researchers are contributing to a quick and coordinated response across the region.

New selection method allows for rapid development of improved maize varieties

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”

New maize hybrid shows resistance to stem borers in South Africa

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.
