“…Solanum torvum has a poor germination rate and slow seedling development but is employed as rootstock for eggplant cultivation because of its vigor and resistance to serious soil-borne diseases as described above (Gousset et al, 2005;Miceli et al, 2014). Moreover, S. torvum has been found to exhibit resistance to M. incognita in several studies conducted in Japan and abroad (Ali et al, 1992; Daunay and Dalmasso, 1985; Dhivya et al, 2014;Hara et al, 1983;Shetty and Reddy, 1985).…”

The southern root-knot nematode Meloidogyne incognita is an important pathogen of solanaceous plants worldwide. To assess resistance and suppressiveness to the nematode of the Japanese cultivars of eggplant rootstocks, we conducted greenhouse experiments. Numbers of nematode egg masses were significantly lower on Solanum tor vum rootstock cultivars, Tonashimu, Torero, and Torvum vigor, than the cultivars of the other Solanum species after 45 days of cultivation. Next, we examined the effect of Tonashimu on the population density of the nematode in soil. After 116 days of cultivation, the second-stage juvenile density of the nematode in soil was reduced, and was significantly lower in pots of Tonashimu, than in those of Solanum melongena cultivars. These results suggest that the Japanese rootstock cultivars of S. torvum are resistant to the nematode, and could suppress nematode density in soil. Nematol. Res. 46(2), 87-90 (2016).Key words: grafting, resistance, root-knot nematode, Solanum torvum INTRODUCTIONEggplant (Solanum melongena) is cultivated worldwide and is especially popular in Asian countries such as China and India. Eggplant was introduced into Japan during the Nara period (AD 710 to 794) and today is an important domestically produced vegetable (Saito, 2004). Many crops, including eggplant, are attacked by the southern root-knot nematode Meloidogyne incognita, resulting in yield losses. In eggplant, 20-29% of total yield is estimated to be lost because of Melodogyne spp. (M. incognita is dominant) in the tropics (Sasser, 1979) and the economic threshold level of eggplant is reported to be 5.4 M. incognita second-stage juveniles (J2) per 100 g soil (Netcher and Sikora, 1990). Recently, Watanabe et al. (2013) reported that soil densities of two J2 per 20 g soil or greater with the Baermann technique have been shown to significantly reduce eggplant yield (cultivar Senryo 2go) at 50 days after planting.Most plant nematode control methods rely on chemical agents. Although soil fumigants such as 1,3-dichloropropene are commonly used, the use of such chemicals is likely to be subject to increasing restriction owing to environmental and safety concerns. The exploitation of resistant cultivars is the most effective and environmentally benign method to reduce nematodeinduced crop loss. However, no eggplant cultivar resistant to M. incognita has been found.Eggplant cultivars grafted onto resistant rootstocks are used to prevent various diseases, including bacterial wilt (caused by Ralstonia solanacearum), and Fusarium wilt (caused by Fusarium oxysporum) (Yoshida, 2004). Solanum torvum has a poor germination rate and slow seedling development but is employed as rootstock for eggplant cultivation because of its vigor and resistance to serious soil-borne diseases as described above (Gousset et al., 2005;Miceli et al., 2014). Moreover, S. torvum has been found to exhibit resistance to M. incognita in several studies conducted in Japan and abroad (Ali et al., 1992; Daunay and Dalmasso, 1985; Dhivya et al., 2014;Ha...

“…It has desirable traits such as disease resistance, which may be transferred by introgression into the eggplant genome (Singh et al, 2006;Baysal et al, 2010). 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).…”

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.

“…Solanum torvum, also known as turkey berry, is of great interest for eggplant breeding since it is resistant to a wide range of soil-borne diseases like root-knot nematodes, Ralstonia solanacearum, Verticillium dahliae, and Fusarium oxysporum f. sp. melongenae (Gousset et al, 2005;Yamaguchi et al, 2010). For S. torvum, the assembly statistics and annotation were slightly different to that of common eggplant, being the most relevant difference the number of unigenes (38,185 for S. torvum versus 34,174 for common eggplant) ( Table 1).…”

Dramatic advances in genomics during the last decades have led to a revolution in the field of vegetable crops breeding. Some vegetables, like tomato, have served as model crops in the application of genomic tools to plant breeding but other important crops, like eggplant (Solanum melongena), lagged behind. The advent of next generation sequencing (NGS) technologies and the continuous decrease of the sequencing costs have allowed to develop genomic tools with a greatly benefit for no-model plants such as eggplant. In this review we present the currently available genomic resources in eggplant and discuss their interest for breeding. The first draft of eggplant genome sequence and the new upcoming improved assembly, as well as the transcriptomes and RNA-based studies represent important genomic tools. The transcriptomes of cultivated eggplant and several wild relatives of eggplant are also available and have provided relevant information for the development of markers and understanding biological processes in eggplant. In addition, a historical overview of the eggplant genetic mapping studies, performed with different types of markers and experimental populations, provides a picture of the increase over time of the precision and resolution in the identification of candidate genes and QTLs for a wide range of stresses, and morphoagronomic and domestication traits. Finally, we discuss how the development of new genetic and genomic tools in eggplant can pave the way for increasing the efficiency of eggplant breeding for developing improved varieties able to cope with the old and new challenges in horticultural production.
