“…Although, male sterility molecular mechanism has been studied in several crops but is still poorly understood in the eggplant. Several genic [93], cytoplasmic [94,95] and genetically engineered [96,97] male sterility system have been developed in eggplant. Genic male sterility is of minimal practical application due to its mode of utilization and maintenance [98].…”

Heterosis (or hybrid vigor) results in a hybrid’s phenotypic superiority over its founder parents for quantitative and qualitative traits. Hybrid vigor is defined by mechanisms such as dominant complementation, over-dominance, and epistasis. Eggplant (Solanum melongena L.) is an essential vegetable crop and a good source of dietary minerals, vitamins, and anthocyanins, with a high oxygen radical absorbance capacity and low caloric value. Given the economic and nutritional significance of eggplants, breeding efforts focus on developing high-yielding varieties—mostly F1 hybrids—with important traits. Studies indicate the successful exploitation of heterosis in the eggplant for a considerable improvement with respect to quantitative traits. In this direction, estimating heterosis for yield-related traits could well be useful for examining the most beneficial hybrid mix with the exploitation of top-quality hybrid. This review examines the current perception of the breeding and molecular aspects of heterosis in eggplants and cites several studies describing the mechanisms. Rendering and combining recent genomics, epigenetic, proteomic, and metabolomics studies present new prospects towards the understanding of the regulatory events of heterosis involved in the evolution and the domestication of the eggplant ideotype.

“…In this respect, using S. melongena as the female parent is usually preferred, as it allows the recovery in the first generation of the S. melongena cytoplasm. This avoids potential sterility problems in backcross generations due to alloplasmy, which has been observed in eggplant lines containing the S. anguivi or S. violaceum cytoplasms (Isshiki and Kawajiri, 2002;Khan and Isshiki, 2011). Also, S. melongena fruit have more seeds than small-fruited wild species (Isshiki and Kawajiri, 2002) and in consequence, theoretically it is possible to obtain more seeds per cross when using S. melongena as a female parent.…”

Wild relatives represent a source of variation for many traits of interest for eggplant (Solanum melongena) breeding, as well as for broadening the genetic base of this crop. However, interspecific hybridization with wild relatives has been barely used in eggplant breeding programs. As initiation of an introgression breeding program we performed 1424 interspecific hybridizations between six accessions of eggplant from the Occidental and Oriental groups and 19 accessions of 12 wild species from the primary (Solanum incanum and Solanum insanum), secondary (Solanum anguivi, Solanum dasyphyllum, Solanum lichtensteinii, Solanum linnaeanum, Solanum pyracanthos, Solanum tomentosum, and Solanum violaceum), and tertiary (Solanum elaeagnifolium, Solanum sisymbriifolium, and Solanum torvum) genepools. Fruit set, hybrid seed, and seed germination were obtained between Solanum melongena and all wild species of the primary and secondary genepools. The highest fruit set percentage and quantity of seeds per fruit were obtained with the two primary genepool species S. incanum and S. insanum as well as with some secondary genepool species, like S. anguivi, S. dasyphyllum, or S. lichtensteinii, although some differences among species were observed depending on the direction of the hybridization. For small-fruited wild species, the number of seeds per fruit was lower when using them as maternal parent. Regarding tertiary genepool species, fruit set was obtained only in interspecific hybridizations of eggplant with S. sisymbriifolium and S. torvum, although the fruit of the former were parthenocarpic. However, it was possible to rescue viable interspecific hybrids with S. torvum. In total we obtained 58 interspecific hybrid combinations (excluding reciprocals) between eggplant and wild relatives. Some differences were observed among S. melongena accessions in the degree of success of interspecific hybridization, so that the number of hybrid combinations obtained for each accession ranged between 7 (MEL2) and 16 (MEL1). Hybridity of putative interspecific hybrid plantlets was confirmed with a morphological trait (leaf prickliness) and 12 single nucleotide polymorphism markers. The results show that eggplant is amenable to interspecific hybridization with a large number of wild species, including tertiary genepool materials. These hybrid materials are the starting point for introgression breeding in eggplant and in some cases might also be useful as rootstocks for eggplant grafting.

Cytoplasmic male sterility (CMS) is a useful system to produce hybrid seeds in a variety of crop species. In eggplant, CMS systems were developed utilizing the cytoplasms of six wild Solanum species by repeated backcrossings. These CMS systems were classified into two types. The first one is anther indehiscent-type sterility in the CMS systems of eggplant with the cytoplasms of Solanum kurzii Brace & Prain, S. violaceum Ort., and S. virginianum L., in which anther contains normal pollen but does not open to release. The second one is pollen non-formation-type sterility in the CMS systems of eggplant with the cytoplasms of S. aethiopicum Aculeatum Group, S. anguivi Lam., and S. grandifolium C.V. Morton, in which anther of the male-sterile lines is completely devoid of pollen. Both types of sterility system were characterized by investigating pollen and seed fertility. Furthermore, in pollen non-formation CMS systems, two independent dominant fertility restorer (Rf) genes were discovered and a sequenced characterized amplified region (SCAR) marker tightly linked to these genes was developed.
