New mango varieties could transform South Africa's fresh export industry

Central to this development is Sun World International's acquisition of the South African-based Biogold Group, which has brought together an extensive portfolio of promising mango varieties, including the exceptionally late-maturing Blyde Late.

South Africa's mango industry is concentrated in the subtropical regions of Limpopo and Mpumalanga, particularly around Hoedspruit, Tzaneen and the Lowveld. Unlike the country's major export fruit industries, mango production has traditionally focused on domestic consumption and processing into atchar, dried fruit and juice, with relatively limited fresh exports.

A major constraint has been the lack of varieties consistently meeting international requirements for quality, appearance, flavour and shelf life. Production has long relied on traditional cultivars such as Tommy Atkins, Keitt, Kent, Sensation and Heidi, some of which face challenges with disease susceptibility, inconsistent yields and a narrow harvesting window.

Tommy Atkins became particularly dominant, concentrating large volumes into the same marketing period and putting pressure on grower returns. According to Subtrop's Derek Donkin, this contributed to the industry's reliance on processing. With limited prospects for profitable fresh exports, growers had little incentive to expand production, and some replaced mango orchards with citrus and avocados.

A significant breakthrough in mango breeding

The outlook began to change with the announcement in August 2024 that international fruit breeding and licensing company Sun World International had acquired the Biogold Group, a South African-based global fruit variety rights manager trading locally as Citrogold.

Biogold had developed an extensive international portfolio of citrus and subtropical fruit varieties, including mango genetics from its own breeding initiatives and partnerships with independent breeders.

The acquisition brought one of the world's largest mango variety collections into Sun World's established international network of breeding, cultivar evaluation, licensing and commercialisation.

For South African growers, the significance is considerable. The partnership offers access to new varieties developed both locally and internationally, together with the expertise and commercial relationships required to introduce these cultivars successfully into global markets.

Viresh Ramburan, vice-president of global licensing for citrus and subtropicals at Biogold, highlighted the opportunity to revitalise the South African industry when the acquisition was announced.

"These new varieties have the potential to change the trajectory of the South African mango industry in the coming decade," Ramburan said.

The portfolio includes promising early-season selections such as Kankun, Lady Jane and Sumango2, developed to deliver superior flavour, attractive appearance and desirable commercial characteristics.

Importantly, these varieties also offer opportunities to extend the harvesting and marketing season, reducing the industry's reliance on concentrated supplies from traditional cultivars.

Blyde Late opens a new marketing window

One of the most exciting developments is Blyde Late, an exceptionally late-maturing mango variety that could provide South African growers with a distinctive advantage in international markets.

While traditional South African mango varieties generally begin disappearing from the market during March and April, Blyde Late can extend commercial availability into May.

This later harvesting period offers the potential to supply customers when conventional South African mango production has largely ended, creating opportunities for more continuous retail programmes and potentially more attractive marketing windows.

Sun World formally launched its global mango programme at the beginning of 2026, showcasing the potential of Blyde Late through international field days and industry presentations.

The variety has attracted particular interest because it demonstrates how targeted breeding can overcome one of the traditional limitations of the mango industry: the relatively short period during which exporters can supply commercially desirable fruit.

For South African growers, Blyde Late could help extend the production season, spread harvesting and packing activities over a longer period and provide access to market opportunities outside the traditional peak supply window.

However, its commercial success will ultimately depend on consistent fruit quality, reliable yields, postharvest performance and the ability to establish sustainable export programmes.

South African research strengthens the varietal pipeline

South African research is also contributing to mango varietal development. Working with the South African Mango Growers' Association (SAMGA), the Agricultural Research Council (ARC) has focused on improving disease resistance, fruit quality and production reliability. In 2024, the ARC introduced four locally bred cultivars, complementing the international breeding programmes of Sun World and Biogold and offering growers new opportunities to produce commercially competitive mangoes.

A new opportunity for South African mango exports

The renewed investment in mango genetics comes at a time when international demand for high-quality mangoes is creating opportunities for greater varietal differentiation.

For South Africa, the availability of new cultivars could address several longstanding constraints simultaneously: improving fruit quality, extending the harvest season, reducing production risks and creating opportunities to enter international markets with more competitive products.

There are still challenges to overcome. Export market access, reliable shipping services, postharvest handling and the development of sustainable customer relationships will remain essential to growing the fresh export sector.

However, the combination of South African breeding expertise and international commercialisation capacity is providing renewed confidence in the industry's future.

After decades in which mango production has been sustained largely by domestic consumption and processing, the development of superior varieties offers the possibility of a different commercial direction.

With the introduction of improved early-season cultivars, distinctive varieties such as Blyde Late, and the international expertise of Sun World and Biogold, South Africa's mango industry has an opportunity to move beyond its traditional limitations and establish a stronger presence in the global fresh fruit trade.
