Abstract
Fusarium oxysporum f.sp. narcissi causes basal rot of Narcissus bulbs.
Commercially grown cultivars are to differing degrees very susceptible to this pathogen, whilst many of the N. tazetta hybrids show increased resistance.
Total resistance to Fusarium species in other crops has been found amongst the wild plant species. Narcissus species hybrids and commercial cultivars are believed to have evolved from a core of fourteen groups made up of nineteen species and sub-species from which all others are derived.

Total resistance to Fusarium species in other crops has been found amongst the wild plant species. Narcissus species hybrids and commercial cultivars are believed to have evolved from a core of fourteen groups made up of nineteen species and sub-species from which all others are derived.
Thirty three species including many of the nineteen core species were screened for resistance to F. oxysporum f.sp. narcissi. The results showed that plants were either wholly resistant, partially resistant or wholly susceptible.
Species within the same core group had a similar level of resistance.
