Leading the research in South Africa is Prof Linus Franke from the Department of Soil, Crop and Climate Sciences.

Scientists are actively pursuing the successful breeding of diploid hybrid potatoes from inbred lines. This is expected to revolutionise potato breeding as it holds the key to rapid genetic progress. It will introduce new varieties for commercialisation through seed. Currently, existing potato variants have a gene that renders self-pollinated seeds infertile.

Prof Linus Franke, an academic in the Department of Soil, Crop and Climate Sciences at the UFS, is leading the research in South Africa. “This technology allows the production of genetically uniform potato seed that is easy to transport and largely disease-free.” He says this differs from conventional breeding whereby only vegetative propagation is possible due to tetraploid varieties in potatoes. It also risks carrying pests and diseases from one generation to the next – leading to the accumulation of pests and diseases with each round of multiplication.

Seed innovation

Prof Franke explains that Solynta BV, a seed company based in the Netherlands that produces potato varieties that can be grown from seed, has included South Africa in their research efforts because it is one of Africa’s largest producers and exporters. Through his academic relationship with Wageningen University and Research, a Dutch institution renowned for its agricultural endeavours and food production, the UFS became involved in researching hybrid potatoes grown from seed.

Diploid seeds containing two sets of chromosomes allow easier gene manipulation to increase predictability and speedier genetic progress. The breeding approach enables the incorporation of tolerance to pests, diseases, abiotic stresses (cold, heat, drought) and other desired genetic traits.

Although Prof Franke is optimistic about this research, he is not blind to disadvantages. “Potato seeds are tiny and have little energy reserves, making it harder to grow potatoes from seed than from tubers.” He says potatoes from seed will take longer to cultivate than tubers, as farmers need to grow plantlets from seeds first, adding six weeks to the growing period. “It is possible that commercial farmers can grow potatoes directly from seed. Alternatively, perhaps more likely, specialised growers will produce tubers of potatoes from seed; these tubers are then sold as seed tubers to other potato farmers, who then continue their normal practices of producing potatoes for the market from tubers.”

Financial benefits

Prof Franke says farmers have reason to get excited. “Seed potatoes will reduce input costs, as varieties with enhanced tolerance to pests and diseases require less pesticides. Planting one hectare of potatoes requires three to four tonnes of potato tubers, but only one 25 g packet of potato seeds.” Since potatoes are a more valuable commodity than maize, this technology might also increase farmers’ income potential.

How do you, as a mother who lost her only daughter, forgive the man who claimed responsibility for the attack that killed her?  How do you forget his crime while travelling with him across the world?  

These were some of the questions posed to Jeanette Fourie at a Dialogue between Science and Society series on forgiveness and living reconciliation. Jeanette, whose daughter Lyndi was killed in an attack on the Heidelberg Pub in Cape Town in 1993, was one of three people telling their stories of forgiveness while dealing with traumatic experiences. 

Sitting next to Letlapa Mphahlele, the man who owned up to the attack that killed her daughter, Jeanette spoke about their story of forgiveness traveling the world together, spreading the message of forgiveness and conciliation. 

"Don't ever think you can forget, because that’s not possible. What you do with the pain is to find peace, and that's what forgiveness does. Forgiveness allows you to stop all the dialogue in your head on why he did it. You don't forget, you confront it and you deal with it." 

Letlapa, Director of Operations of Apla, the military wing of the PAC at the time of Lyndi's death, spoke about dealing with the response to his crime. "Sometimes you wish that you were not forgiven, because now you have the great burden of proving that you are worthy of forgiveness."

Also telling her story of forgiveness was Olga Macingwane, a survivor of the Worcester bombing of 1993 in which four people were killed and sixty-seven others injured. Four people were sent to prison. In 2009 Olga met one of the perpetrators, Stefaans Coetzee, and what came out of that meeting, is her story. 

"When I met Stefaans I was very angry, but when you sit down with somebody and listen to him or her, you find out what the reasons were that made him or her do something. I can say that I forgave him." 

Facilitating the conversation, Prof Pumla Gobodo-Madikizela, Senior Research Professor on Trauma, Forgiveness and Reconciliation, said the seminar was meant to get in touch with the truth that forgiveness is possible. 

"Before we had the Truth and Reconciliation Commission (TRC) in South Africa, the experts always said that forgiveness was not possible in these stories of the past. And then the TRC came into life as a response to mass atrocities. For the first time in the history of these traumatic experiences, of political traumas, we witness something that we have never seen.  Even us on the TRC, although it was framed as reconciliation, we never imagined there would actually be stories of forgiveness emerging out of that process, and then we witness that this too is possible." 

Others who took part in the two-hour-long seminar, were Dr Juliet Rogers, a Scholar on Remorse from the University of Melbourne in Australia and Dr Deon Snyman, Chairperson of the Worcester Hope and Reconciliation Process. They spoke about the dynamics behind the processes of engagement between victims/ survivors and perpetrators. 

The Dialogue between Science and Society series was co-hosted by the Institute for Reconciliation and Social Justice.
