There is an ongoing need to extend postharvest storability of field crops intended for export. This challenge is particularly significant in leafy vegetables and herbs. The attractive form and distinctive flavor of rucola leaves have made this crop plant a popular choice, both for salads and as a garnish; however its production and marketing have been limited by early flowering and poor storability. The newly developed rucola cultivar, named ‘Rock-Ad’, was developed by our group through advanced breeding techniques from wild rocket seeds, involving screening of progenies for desired characters which have a linked regulation. ‘Rock-Ad’ has the potential to be the cultivar of choice for growers and customers due to its enhanced characteristics including late flowering, which enables several harvests per season. It is also suitable for sea shipment due to improved storability.
