“…To control this disease, a disease-resistant variety is required as a rootstock. Laboratory tests of C. fimbriata inoculation (Kato et al, 1982;Morita et al, 2011;Shimizu and Miyoshi, 1999) found reduced spreading of lesions and lower mortality in the saplings of several fig varieties, including 'Celeste' ['Malta' sensu (Condit, 1955)], 'Boldido Negra', 'Negronne' ['Bordeaux' sensu (Condit, 1955)], and 'Ischia Black'. The lower mortality in 'Celeste' was described in an earlier report (Kato et al, 1982), and some growers commenced a test planting of 'Masui Dauphine' grafted on 'Celeste' rootstock.…”

“…'Masui Dauphine' is particularly prone to infection, whereas 'Celeste' is relatively resistant (Hosomi and Kawaradani 2004). Togawa et al (1999) Morita et al 2011) and might therefore be suitable for use as a resistant rootstock. Unfortunately, the grafting compatibility between F. carica and F. erecta is extremely low: because of poor callus development at the graft union, use of F. erecta as a rootstock is not practicable (Hosomi 1993).…”

Ceratocystis canker, which is caused by the fungus Ceratocystis fimbriata Ellis et Halsted, is one of the most severe diseases of the common fig (Ficus carica L.). In contrast, the wild fig species F. erecta Thunb. is resistant to this fungus. We performed interspecific hybridization between the common fig (seed parent) and F. erecta (pollen parent) through artificial pollination. Even though hybrid seeds showed high germination rates, the seedling survival rates were low. All of the seedlings contained the expected simple sequence repeat (SSR) alleles from both common fig and F. erecta at each of the three loci tested, thus confirming the parentoffspring relationships of the interspecific hybrids. The leaf morphological characters of hybrid seedlings were intermediate between those of the parents. Cuttings of cultivars of common fig, F. erecta, and hybrid seedlings were inoculated with C. fimbriata by direct wounding of the shoot. All of the common fig cultivars tested withered and died within 10 weeks. Leaves and shoots of the hybrids and F. erecta were healthy 100 days after inoculation. Our results suggest that interspecific hybridization between the common fig and the wild species F. erecta is a breakthrough in the breeding of a new fig rootstock source with resistance to Ceratocystis canker.

“…A wild fig relative, F. erecta (2n = 2x = 26), possesses resistance to Ceratocystis canker (Morita et al, 2011; Shimizu and Miyoshi, 1999). However, introducing resistance characteristics into common fig from F. erecta has proved challenging.…”

AbstractFicus erecta, a wild relative of common fig (F. carica), is a donor of Ceratocystis canker resistance in fig breeding programs. Interspecific hybridization followed by recurrent backcrossing is an effective method to transfer the resistance trait from wild to cultivated fig; however, this is time consuming and labor-intensive for trees, especially for gynodioecious plants such as fig. In this study, genome resources were developed for F. erecta to facilitate fig breeding programs. The genome sequence of F. erecta was determined using single-molecule real-time sequencing technology. The resultant assembly spanned 331.6 Mb with 538 contigs and an N50 length of 1.9 Mb, from which 51,806 high-confidence genes were predicted. Pseudomolecule sequences corresponding to the chromosomes of F. erecta were established with a genetic map based on single nucleotide polymorphisms from double-digest restriction-site associated DNA sequencing. Subsequent linkage analysis and whole genome resequencing identified a candidate gene for the Ceratocystis canker resistance trait. Genome-wide genotyping analysis enabled selection of female lines that possessed resistance and effective elimination of donor genome from progeny. The genome resources provided in this study will accelerate and enhance disease resistance breeding programs in fig.
