“…Grafting has been utilized to manage bacterial wilt in tomato crops worldwide (11,24,25,30,39), and has been proposed recently in the United States for open-field and high-tunnel production (22,33). Breeding lines CRA 66 and Hawaii 7996 were found to significantly reduce bacterial wilt incidence in naturally infested soils in North Carolina (33).…”

Rivard, C. L., O'Connell, S., Peet, M. M., Welker, R. M., and Louws, F. J. 2012. Grafting tomato to manage bacterial wilt caused by Ralstonia solanacearum in the southeastern United States. Plant Dis. 96:973-978.Bacterial wilt, caused by Ralstonia solanacearum, can result in severe losses to tomato (Solanum lycopersicum) growers in the southeastern United States, and grafting with resistant rootstocks may be an effective strategy for managing this disease. However, R. solanacearum populations maintain considerable diversity, and little information is known regarding the efficacy of commercially available rootstocks to reduce bacterial wilt incidence and subsequent crop loss in the United States. In this study, tomato plants grafted onto 'Dai Honmei' and 'RST-04-105-T' rootstocks had significantly lower area under the disease progress curve (AUDPC) values compared with nongrafted plants (P < 0.05). Across three locations in North Carolina, final bacterial wilt incidence for non-and self-grafted plants was 82 ± 14 to 100%. In contrast, bacterial wilt incidence for the grafted plants was 0 to 65 ± 21%. Final bacterial wilt incidence of plants grafted with Dai Honmei rootstock was 0 and 13 ± 3% at two locations in western North Carolina but 50 ± 3% at a third site in eastern North Carolina. Similarly, grafting onto RST-04-105-T rootstock significantly reduced AUDPC values at two of the three locations (P < 0.05) compared with that of the nongrafted plants, but performed poorly at the third site. Total fruit yields were significantly increased by grafting onto resistant rootstocks at all three sites (P < 0.05). Regression analyses indicated that yield was significantly negatively correlated with bacterial wilt AUDPC values (R 2 was 0.4048 to 0.8034), and the use of resistant rootstocks enabled economically viable tomato production in soils naturally infested with R. solanacearum.

“…Several studies have shown that S. torvum has high levels of resistance towards pests, nematodes and pathogens (Collonnier et al, 2003;Clain et al, 2004;Gousset et al, 2005). It has been used as a rootstock for the grafting of susceptible tomato and eggplant varieties (Peregrine and Ahmad, 1982;Singh and Gopalakrishnan, 1997). Moreover, interspecific crosses between plant species are an ideal way for introducing desirable genetic traits in breeding programs.…”

ABSTRACT.Interspecific hybrids between cultivars of eggplant (Solanum melongena L.) and its wild relative S. torvum, which has disease resistance and desirable traits for crop improvement, were obtained by cross-hybridization and embryo rescue. Twenty-one hybrid progenies were obtained and examined based on morphological traits, RAPD and ISSR markers. Five of them were confirmed to be true interspecific hybrids. Eighteen and 14 bands from 7 RAPD and 14 ISSR primers, respectively, were polymorphic and present in all five hybrid seedlings and their parents. The morphological characteristics of leaf margin, inflorescence type and spine positions of the five seedlings were intermediate to the parents. These interspecific hybrids had low pollen viability, probably due to abnormal meiosis.

“…This disease, if not controlled, may result in the death of all plants in a specific sowing in soils where some years of continuous cropping has taken place; fields may need to be excluded from the production of solanaceous crops (Rivard et al 2012). In studies conducted in Brunei, Peregrine and Ahmad (1982) demonstrated effective control of this disease with tomato varieties such as Roma grafted onto S. torvum rootstocks. Thirty years later, Cardoso et al (2012) Lin et al (1998) evaluated two popular local tomato cultivars, Farmers 301, susceptible to bacterial wilt, and Taichung ASVEG No.…”

“…King et al (2010) report that the current genetic base of commercial rootstocks used in the grafting of tomato is very limited in relation to the broad spectrum of closely related species that might be employed in this capacity. They suggest that plant breeders facing the challenges of rapidly changing biotic, and abiotic stresses will soon need new rootstock germplasm, as those currently used, such as tomato rootstock Hawaii 7996 (VI043614), are now more than 30 years old (Peregrine & Ahmad 1982). At that time, Hawaii 7996 was used as a resistant cultivar rather than as a rootstock.…”

This paper reviews the status of the use of grafting in two solanaceous crops of global importance, tomato and eggplant, for the control of biotic and abiotic stresses. Flooding and soil-borne diseases cause severe crop losses of tomato during the hot and wet summer months in the lowland tropics. Asian Vegetable Research and Development Center (AVRDC) recommended since 2003 the use of eggplant rootstocks VI046103 (EG195) and VI045276 (EG203) for grafting tomato scions to provide a high degree of tolerance and resistance against flooding, bacterial wilt, root-knot nematodes and other soil-borne diseases. These two eggplant rootstocks and the tomato rootstock VI043614 (Hawaii 7996) are widely used in Southeast and East Asia for successful tomato production in both the tropical lowlands and highlands, providing significant economic returns to farmers. Given the rapid evolution of plant pathogens that might cause a breakdown of the limited rootstocks currently available, as well as the challenges of other abiotic stresses such as salinity and supra-optimal temperatures, it is necessary to expand the search for new rootstocks and evaluate new rootstock-scion combinations. Breeding and evaluation of appropriate rootstocks is still a matter of trial and error because desired rootstock traits, especially for abiotic stresses, are quite complex and regulated by multiple genes. Physiological and genetic markers to guide the selection process are still lacking but are essential to fast-track the identification of rootstocks with multiple benefits. This review supports an initiative to upgrade grafting technology through evaluation of a new and wider range of rootstocks sourced from the AVRDC genebank.
