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.

Minister Jeff Radebe commends UFS for measures taken to address racial prejudices

Minister Jeff Radebe lecture: YouTube video

Mr Jeff Radebe, Minister of Justice and Constitutional Development, last night delivered a lecture in the Prestige series of the Dean: Faculty of Law, at the Bloemfontein Campus of the University of the Free State (UFS).

In a packed hall with, among others, university students, staff and members of the judicial system, Minister Radebe said that many other academic institutions should look to the UFS when they deal with the challenges of racism in its various manifestations in their midst. “I commend the university for taking drastic measures to address the challenges of racial prejudices in its own backyard,” he said.

“Government can and must provide leadership, but it is the collective efforts of all our people that will ensure that we bridge the racial and historical divides that stand in contrast to our noble virtues as entailed in the Constitution,” the Minister said.

On the topic “Access to Justice” the Minister said that the Department of Justice and Constitutional Development has channelled more than 80% of its nearly R16 billion budget to the Access to Justice programme.

Minister Radebe talked about the reintroduction of the Sexual Offences Courts, which attests to the unrelenting resolve to eliminate the scourge of gender-based violence. “Fifty-seven of the department’s Regional Courts are being upgraded to operate as dedicated Sexual Offences courts during the 2013/2014 financial year. We believe that these sexual offences courts will help address the growing challenge of sexual offences in the country, particularly against vulnerable groups.”

The Minister also pleaded with law teachers to avail themselves to preside in the courts in our country to complement the decreasing number of presiding officers that are drawn from the attorneys’ and advocates’ profession. These services are normally rendered by the Commissioners pro bono as part of an endeavour to bring justice to all the people, including the poor.

A challenge that the UFS could help resolve,is the transformation of the legal profession. “We need to increase the number of Law students and in turn increase the number of attorneys and advocates in the pool from which we derive candidate judges,” Mr Radebe said.

The Legal Practice Bill and the transformation of the State Legal Service are the most important initiatives underway by which the Institutions of Higher Learning will make a contribution. “The Bill seeks to establish a single regulatory structure, which will be responsible for setting the norms and standards for all legal practitioners. Members of the public, as primary beneficiaries of the legal profession, will also be represented in this structure. Other important objectives of the Bill are the removal of barriers of entry to the profession for young law graduates who aspire to pursue a legal career, and the introduction of measures aimed at ensuring that fees chargeable for legal services are reasonable and within reach of ordinary citizens,” he said.

The Minister concluded: “Our courts must reflect both the race and gender demographics of our country and so must the university communities in their various capacities as a microcosm of the society we seek to build.”
