The Tomato Brown Rugose Fruit Virus (ToBRFV) is affecting all varieties of tomatoes and is spreading
worldwide. NRGene partnered with Philoseed to develop HR (high resistant) varieties
Our high resistance source has been tested successfully by several seed companies!
We currently oﬀer early access to seeds containing the QTLs and selection markers (patent pending).

No, the ToBRFV resistance trait was co-developed with Philoseed and an independent IP protection claim has been filed.
The background used for the introgression process is a cultivated line for the big fresh tomato sector, indeterminate type.
No linkage drag has been observed for any obvious phenotypes including male sterility or plant and fruit size
