The N′ gene was shown to be present in the ‘Samsun NN’ line of Nicotiana tabacum by its differential response to tobacco mosaic (TMV) and tomato mosaic (ToMV) viruses in the segregating and test‐cross generations of the cross ‘Samsun NN’בSamsun nn’. The appearance of phenotypes reacting with local necrosis to ToMV and with systemic mosaic to TMV confirmed that the genes N and N′ are on distinct loci. An isogenic N′;N′ Samsun line was selected.
