Share this

11 March 2021, New Delhi, IN: The New Delhi virus has been causing serious problems for squash growers in the Mediterranean region for close to a decade. The plant virus can attack the foliage and the fruits in any stage of cultivation, resulting in smaller, misshapen fruits and ultimately a lower yield. Following years of research, vegetable breeding company Rijk Zwaan has now introduced the first squash varieties with resistance to the New Delhi virus.

A team of researchers and breeders from Rijk Zwaan in the Netherlands, Spain and Italy have succeeded in developing a number of high-yielding squash varieties with particularly good fruit quality and the resistance to the New Delhi virus. “There is huge market demand for such products. Even though Rijk Zwaan is still a relatively small player in squash, we wanted to offer a solution for growers who are affected by this virus,” comments María Lourdes Pérez Aguilera, Squash Breeder at Rijk Zwaan in Spain. The company has now taken an important step in this segment with the launch of squash varieties with resistance to the New Delhi virus.

Benefits throughout the chain

This resistance is not only of great interest to squash growers, but also offers significant benefits for other partners in the fresh produce value chain. After all, a more stable supply of higher-quality and more sustainable products can help to improve the sales market at various stages in the chain.

Extending the reach

Rijk Zwaan is working hard to ensure that varieties with resistance to this unpredictable virus are available for as many growers as possible. The first batches of seeds have already been supplied to a group of selected growers for use in the upcoming season. In parallel with the production process, the Rijk Zwaan team is continuing the breeding work to extend this resistance to the company’s other open field and protected cultivation squash varieties.

Defense label indicates strong and resilient varieties

As a vegetable breeding company, Rijk Zwaan is constantly innovating to develop strong and resilient varieties that produce high-quality vegetables in various climate zones and under various growing conditions. Rijk Zwaan markets its varieties that have groundbreaking, innovative resistances under the Defense label. The squash varieties with New Delhi resistance definitely fall into that category and will therefore be sold under the DelhiDefense label.
