In tomato, for example the large S. chilense introgression fragment on chromosome 6 (about 27 cM) which comprises the Ty-3 allele has been reduced by selecting a recombinant progeny line (LA1931-AL-F2), which comprises a much smaller S. chilense introgression fragment (about 6 cM) comprising Ty-3 (see Ji et al. An alternative is the use of whitefly-resistant plants (Bas et al 1992, Nombela et al 2001). ID AATTTT tabaci biotype B resistant plantsâ refers to resistance against B. tabaci biotype B conferred by the Wf allele (or by the Wf orthologous allele) when present in the C. melo genome in one or two copies (i.e. 19 mME40109 Other resistance genes, against pathogenic viruses, fungi, bacteria or pests may also be introduced. The presence or absence of the recombinant chromosome 11, and of the introgression fragment, may be determined by one or more of the molecular marker assays described herein and/or by (a) whitefly-resistance assay(s).

Eduardo et al., Estimating the Genetic Architecture of Fruit Quality Traits in Melon Using a Genomic Library of Near Isogenic Lines, Journal of the American Society of Horticultural Science, 2007, vol. GCCGTGTAGCGTCTCTCTCTAAAACAGACATT Surprisingly, in both mapping populations, a highly significant QTL for Wf-resistance was found on melon chromosome 11, indicating that different wild Cucumis melo accessions comprise a Wf-resistance locus on chromosome 11, which was transferred into cultivated C. melo and conferred Wf-resistance onto the cultivated melon plant. These may be labelled as containing cultivated melon seeds having whitefly resistance.

NCIMB 41966 Any wild melon or wild-relative of melon genome-specific marker in-between two markers (or flanked by two markers, which can be referred to as flanking markers) refers to (the resistance genotype of) any molecular marker which maps genetically to the chromosome 11 region in-between the markers (see FIG. 2, 2012, p 1-6 and Gonzales et al. Both these wild C. melo accessions have a Wf-resistance phenotype as shown in the Examples. Thus, using this method one can detect the presence of an introgression fragment on chromosome 11 comprising QTL Wf_11.1 in cultivated melon plants or plant parts. melonis (Fom) race 2, Fusarium oxysporum f.sp. [A/G] [A/C] In contrast to the European cantaloupe, the North American âCantaloupeâ is not of this type, but belongs to the true muskmelons. [A/G] Seeds deposited under NCIMB 41965 were obtained from the ARS-GRIN collection and have an unknown origin. In a further embodiment, the invention provides for a method of producing a new cultivated melon plant which comprises an introgression fragment which confers whitefly-resistance when in homozygous or heterozygous form, as described.
