Market-leading cucurbit varieties

High-quality seed varieties deliver year-round value

Syngenta’s watermelon, cantaloupe, cucumber, and squash varieties deliver fruit with dynamic adaptability and industry-leading disease resistance packages. 
But the benefits of Syngenta’s cucurbits don’t stop with the grower — they deliver value to distribution, retail, and the end consumer. Our extensive range of varieties offers consumer benefits such as fruit quality, texture, and delicious flavors. Long shelf-life and more durable fruits during handling offer benefits to both distribution and retail partners.

Here are some of the ways we are helping growers be more successful:

Our Woodland site in California serves as a hub for corn, cucurbit, and fruiting vegetable research. Greenhouses, specialized plant growth environments, and an innovative plant pathology lab provide the opportunity for innovation and collaboration across a wide variety of crops, such as seedless watermelon varieties.

Watermelon varieties for every grower

At Syngenta, we offer a wide range of options so growers can access the perfect watermelon seeds that provide consumers with the attributes they prefer, including seeded, seedless, large, or small.

Seeded watermelon

Our lineup of seeded watermelon varieties offers growers reliability and adaptability both as the main crop and when used as a secondary crop to pollinate seedless watermelon. The portfolio includes varieties like Manchester watermelon, which has become a leading variety in Brazil thanks to its consistency, excellent internal quality, and good transportability to markets and kitchen tables across the country. We also offer Estrella and Sangria, both as seeded and seedless, that offer early maturity, delicious flavor, and appealing external and internal quality suitable for retail and roadside stands. One of our more recent introductions, Fahari, is a jubilee rind large, seeded fruit that offers growers reliable yields, good uniformity, and delicious red, high-sugar flesh that easily makes the journey to markets across Sub-Saharan Africa.

Supporting global melon production through innovation

By leveraging our world-class genetics along with trusted grower and shipper relationships, we enable year-round production across the globe. 

Ideal melons

IDEAL Melons

With the IDEAL Melons lineup, consumers around the world will have access to tasty, fresh cantaloupe all year — even in the heart of winter. Our adaptable varieties have good shelf life, transportability, and durability during processing. Whether the melon is grown in South Africa, Central America, or your backyard, it can be delivered to grocery shelves for everyone to enjoy all year.

“IDEAL Melons have the ideal profile with the ideal flavor, musky aromatics, fruit color, and freshness, even in the dead of winter.” — Bernie Hamel, Value Added Chain Lead, Syngenta Vegetable Seeds

Harvest Indicator Trait

With our new Harvest Indicator Trait, the cantaloupe rind changes from green to a golden straw color indicating the IDEAL time to harvest from the field, the IDEAL time to ship to distribution centers, and the IDEAL time to stock shelves. This means that growers and retailers can see and smell product quality in the field and on the shelf, and they can select melons at the peak of ripeness to delight consumers with delicious, fresh fruit every time.

Quality cucumber varieties with high yield potential

With disease resistance, yield potential, and quality, our cucumber varieties reflect Syngenta’s commitment to place growers and sustainability at the heart of everything we do.

Becoming more sustainable

We are committed to helping growers, processors, and retailers reduce their reliance on single-use plastic by developing cucumber varieties that do not require plastic wrap, thanks to hearty skin that does not puncture.  A popular crop in Spain and the Netherlands, these varieties can travel around the world and stay shelf stable, helping achieve sustainability targets today and for the future.

Adapting to new challenges

Tomato Leaf Curl New Delhi Virus (ToLCNDV) is a threat to many cucurbit species, including cucumber. We introduced Siriana with ToLCNDV resistance to support high yield potential for growers and high fruit quality for consumers. Research is ongoing to expand our resistance lineup in cucumbers and other cucurbit species.

“Our intention is to reach the market with the highest shelf life and freshness for the consumer.” — Pedro Pleguezuelo, Syngenta Portfolio Manager, Melon and Cucumber

Meeting market needs with a broad portfolio of squash varieties

With decades of experience in squash breeding, Syngenta offers a full lineup of healthy squash with high yield potential. Varieties include both short- and long-cycle options to meet market needs, along with disease resistance or tolerance to common threats in squash. In addition, growers can choose from squash varieties that display uniformity, good color, and other traits that are important to the fresh market.


Genetics that perform

Through our squash breeding program, we select genetics that feature stronger disease resistance to the most common potyviruses, including Zucchini Yellows Mosaic Virus (ZYMV) and Watermelon Mosaic Virus 2 (WMV2), and increased versatility to ultimately drive lower production costs through:

Zefiros squash

The Zefiros squash is perfect for the shorter summer season, as it maintains yield potential throughout hot temperatures. It is resistant to Cucumber Mosaic Virus (CMV), ZYMV, WMV2, and Papaya Ringspot Virus (PRSV), further supporting a consistent, predictable harvest. The fruit quality is maintained after harvest, creating high demand from traders. Thanks to its upright and open plant architecture, Zefiros can be harvested up to 30% faster than other zucchini and courgette varieties. With rising labor costs, this improvement can make a huge difference.
