Tackling low protein in sweetpotato,

Africa’s ‘superfood’

Imagine a crop that is exceptionally nutritious and can produce good yields in poor conditions with minimal labour.

That crop is sweetpotato, prized as a crucial food security buffer that is packed with edible energy and provides substantial quantities of vitamins A, B and C. It does, however, have one weakness — low protein content — which recent ACCI graduate Dr Sonia Naidoo chose to focus on for her PhD research.

Student breaks new ground with FAW-resistance breeding project

“There is hope for Africa,” said Chapwa Kasoma about her ground-breaking work on breeding maize that is resistant to the dreaded fall armyworm.

The fall armyworm (FAW), first spotted in Africa in 2016, is a global scourge, infecting 350 host-plant species, and causing annual losses of US$2,5-6,2 billion in the main maize-producing countries of sub-Saharan Africa.

Major collaborative wheat-breeding project bears fruit

A six-year-long project at the ACCI to breed drought-tolerant bread wheat with multiple attributes is bearing fruit. Selected elite breeding lines are now available to breeders and growers in sub-Saharan Africa.

The ACCI project, which started in 2014, is being supervised by Professor Hussein Shimelis (pictured left) and funded by the National Research Foundation, Water Research Commission, Alliance for a Green Revolution in Africa (AGRA), Rockefeller Foundation, ARC and UKZN. So far six students have been involved.

PhD project tests the effect of silicon on wheat quality

A novel ACCI research project to breed silicon-efficient wheat that is drought-tolerant, more nutritious and high yielding is showing promising results.

The study, which is being carried out by PhD student Marylyn Christian, is part of a larger ACCI project to breed climate-smart wheat with multiple desirable traits.

Breeding drought-tolerant wheat without losing quality

A PhD student at the ACCI, Zamalotshwa Thungo, has tackled a burning issue affecting global wheat production — breeding for drought-tolerance without loss of quality.

Although plant breeders are successfully breeding for increased yield, this is usually at the expense of grain quality, due to a generic inverse association between the two traits.

Kudos for our professors

UKZN has announced its list of the Top 30 Published Researchers for 2019 and both our profs are again mentioned — for the third year in a row!

Prof Hussein Shimelis is ranked seventh and Prof Mark Laing is 29th.

This follows the news in October that SciVal, an online platform that tracks the performance of over 14 000 research institutions around the world, had ranked Shimelis 49th in South Africa for scholarly output for 2017-2020 and second in the country in the category of Biological and Agricultural Sciences.

Laing was 116th in SA and 6th in the Biological and Agricultural Sciences section.

Shimelis has also been nominated by the Southern African Plant Breeders’ Association for possible acknowledgment as one of Africa’s top 20 plant breeders of 2020. Three other members of the ACCI family have also been nominated: Prof John Derera, Prof Rob Melis and Prof Pangirayi Tongoona.

The Top 20 will be announced before the end of November.

High hopes for South African cassava project

The African Centre for Crop Improvement is poised to become a key player in a move to kick-start large-scale cassava production in South Africa.

PhD student advances work on breeding climate-smart wheat

The clamour for action around climate change has never been louder, but few would imagine that this action includes getting up early to emasculate plants.

AGRA funds two-year study of ACCI impact

Millions of dollars have been spent on training the ACCI’s 120 PhD graduates since 2006. Has it been worth it?

Pro-Vitamin A maize first for South Africa

Dr Aleck Kondwakwenda was on track to become a soil scientist, when he became fascinated by the idea that the nutrient content of crops could be boosted through plant breeding.

Prof Shimelis does training in 3 African countries

The ACCI’s deputy-director, Prof Hussein Shimelis, a regional expert in mutation breeding, travelled to three African countries recently to to share his knowledge.

Possible role for ACCI in SA dryland rice initiative

The ACCI’s Prof Mark Laing and Dr Isack Mathew attended a high-level meeting in May to discuss the production of dryland rice in South Africa.

Making strides with groundnut CLSD resistance

One of the ACCI’s recent graduates, Dr Eluid Kongola, has produced research related to breeding for resistance to Cercospora leaf spot diseases (CLSD).

Stalwart retires after 15 years training plant breeders

Prof Rob Melis was in the first batch of staff recruited by Professor Mark Laing in 2003, a year after the centre opened its doors.

Prof Laing receives long-service award

Prof Laing recieved a long-service award from the University of KwaZulu-Natal, for his work and dedication to the university and students for the past 35 years.

ACCI visit to India cements bond with ICRISAT

The African Centre for Crop Improvement has been strengthening ties with an important international partner.

Promising results in two-fisted approach to tackling Striga on maize

The ACCI’s pioneering efforts to combat Striga, with a two-pronged approach that combines breeding and biocontrol, have yielded more encouraging results.

Symbiotic fungus dramatically enhances drought tolerance in maize

Increasing the level of Trichoderma, a fungus that occurs naturally in soils around the world, makes some varieties of maize more drought tolerant, as well as boosting yield and general plant health.

Boosting drought tolerance in wheat by developing the root system

Going somewhat against the grain, ACCI student Isack Mathew has spent the last three years of his life focusing on how to develop a bigger root system in wheat.

ACCI sweet sorghum varieties poised to boost biofuel industry

A breakthrough by the African Centre for Crop Improvement in the breeding of sorghum could have far-reaching implications for the biofuel and bioplastic industries in South Africa.

Funding will bring Striga-Resistant Sorghum to Farmers

The battle against Striga in Tanzania and South Africa took a step forward with the arrival of funding to register and commercialise new varieties of Striga-resistant sorghum, developed by our recent graduate, Dr Emmanuel Mrema.
