Differential interaction between melon cultivars and race 1.2 of Fusarium oxysporum f.sp. melonis.
One hundred and ten melon accessions from different origins were evaluated for resistance to race 1.2 of Fusarium oxysporum f.sp. melonis (Fom). Artificial inoculations were performed and plants were scored for presence or absence of symptoms. The screening revealed that sources of resistance to this fungus are limited. However, a few resistant accessions were found. The accessions 'Kogane Nashi Makuwa', 'C-211' and 'C-40' from Japan provided the highest resistance to both patotypes of race 1.2 of Fom which seems to confirm that the Far East is a rich area in resistances to this race. We also detect an interesting degree of resistance in 'BG-5384', a Portuguese accession that may be classified as belonging to the botanical variety inodorus.
