“…In vegetable crops of the Solanaceae, resistance to soil-borne diseases has been introduced from wild into cultivated species through somatic fusion; this is particularly true in tomato (Lefrancois et al 1993) and potato (Austin et al 1988;Deimling et al 1988;Brown et al 1995;Laferriere et al 1999;Fock et al 2000). Likewise, somatic hybridisation has been successfully applied to obtain interspecific hybrids between eggplant (Solanum melongena) and its relatives resistant to soil-borne diseases caused by nematodes, Verticillium, Fusarium and Ralstonia (Gleddie et al 1986; Guri and Sink 1988;Sihachakr et al 1988;Daunay et al 1993;Sihachakr et al 1994;Jarl et al 1999;Collonnier at al. 2001).…”

Androgenic dihaploids from somatic hybrids between Solanum melongena and S. aethiopicum group gilo as a source of resistance to Fusarium oxysporum f. sp. melongenae

Dihaploid plants were obtained through anther culture of somatic hybrids between eggplant and Solanum aethiopicum gilo. The androgenic origin of the dihaploids was demonstrated by ploidy determination (flow cytometry and chloroplast counting) and isozyme and molecular (I-SSR and RAPDs) analyses. The androgenic plants showed significant morphological variability in the traits analysed. Pollen viability in the diploid androgenic plants was drastically reduced with respect to the somatic hybrids; however most of the dihaploids produced parthenocarpic fruits. S. aethiopicum and the somatic hybrids showed complete resistance to fungal wilt caused by Fusarium oxysporum f. sp. melongenae. Out of the 41 dihaploids inoculated, 34 were symptomless. The population of androgenic plants developed may represent a useful source for introgression of the Fusarium resistance trait into eggplant.

“…Another technique known as somatic hybridization has also been attempted for transferring useful genes from wild species to cultivated plants through protoplast fusion (Jarl et al, 1999;Kashyap et al, 2002). However, the lack of reports on subsequent integration of interspecific hybrids or somatic hybrids in eggplant breeding programs suggests some remaining obstacles for these hybrids.…”

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.

“…Protoplast culture and plant regeneration Numerous attempts to transfer disease resistance from wild eggplant species to the edible S. melongena by producing somatic hybrids have been reported (Gleddie et al 1986;Guri and Sink 1988;Sihachakr et al 1989;Daunay et al 1993;Jarl et al 1999;Collonnier et al 2001). These attempts, however, were unsuccessful from an agronomical point of view, because undesirable traits such as unattractive fruit shape or poor taste were frequently also transferred to the edible eggplant.…”

“…However, resistance to bacterial wilt has been described in several wild species of the genus Solanum (Sakata et al 1989). To transfer the resistant traits to the edible eggplant, some workers have attempted to produce somatic hybrids by protoplast fusion between eggplant and related wild species (Guri and Sink 1988;Sihachakr et al 1989;Stattmann et al 1994;Jarl et al 1999). This technique has been preferred to sexual crossing, because most sexual hybrids in Solanum have been obtained only through the culture of embryos; moreover, F1 plants were mostly sterile (McCommon and Homa 1983).…”

Protoplast fusion was performed between a commercial rootstock variety of Solanum integrifolium that is widely used in the cultivation of edible eggplant, and Solanum violaceum, a wild eggplant species tolerant to bacterial wilt. One of the somatic hybrid lines (27-14) obtained showed morphological traits intermediate between those of its parents. Its hybrid nature was confirmed by analysis of random amplified polymorphic DNA and restriction fragment length polymorphism patterns. Microscopic observation revealed that the line was amphidiploid. The hybrid line and both parent species were infected with a virulent strain of Ralstonia solanacearum by the root cutting method. Line 27-14 developed much less severe symptoms of bacterial wilt than the susceptible S. integrifolium. Twenty days after inoculation, the bacterial density in the shoot apex tissue was significantly lower in the hybrid than in S. integrifolium, suggesting that the multiplication of bacteria was inhibited in line 27-14.
