Description
Royal Oporto — a medium-late hybrid of red bulb onion with a maturity period from 115 to 125 days. The bulbs have a flat-round shape and an attractive dark-red color with a purple tint. The average fruit weight ranges from 150 to 250 grams, and the flesh is light-purple. High dry matter content, reaching up to 8%, makes this onion the hardest among red varieties, ensuring excellent storability and the ability to be stored for up to 6 months after harvest. A dense shell of dry scales facilitates mechanized harvesting and long-term storage until spring.
The hybrid exhibits high yield potential, reaching up to 100 tons per hectare, and uniform bulb size.
