In the official publications of the Seminis company, information about an onion variety or hybrid named Delta is absent. It is likely that the name was mistakenly transferred from the watermelon variety Delta, which is indeed represented in the portfolio of this company.
In a number of European sources, the variety Delta or Delta Gigant is mentioned, which is described as a variety propagated by seeds. Furthermore, there are offers for "Delta F1" seeds on the market, positioned as a hybrid with a vegetation period of 110–120 days, a rounded bulb shape, and suitability for storage.
