“…In cultivated eggplant, introgression breeding of resistance, originating from related species, has been limited until now ( Daunay, 2008 ). However, crossability studies have illustrated the potential of introgression breeding ( Behera and Singh, 2002 ; Premabati et al, 2015 ; Kaushik et al, 2016 ; Plazas et al, 2016 ). Whereas the majority of Solanaceae crop species originate from the New World (tomato, potato, and pepper), eggplant and its wild relatives are native to the Old World.…”

Eggplant Resistance to the Ralstonia solanacearum Species Complex Involves Both Broad-Spectrum and Strain-Specific Quantitative Trait Loci

Bacterial wilt (BW) is a major disease of solanaceous crops caused by the Ralstonia solanacearum species complex (RSSC). Strains are grouped into five phylotypes (I, IIA, IIB, III, and IV). Varietal resistance is the most sustainable strategy for managing BW. Nevertheless, breeding to improve cultivar resistance has been limited by the pathogen’s extensive genetic diversity. Identifying the genetic bases of specific and non-specific resistance is a prerequisite to breed improvement. A major gene (ERs1) was previously mapped in eggplant (Solanum melongena L.) using an intraspecific population of recombinant inbred lines derived from the cross of susceptible MM738 (S) × resistant AG91-25 (R). ERs1 was originally found to control three strains from phylotype I, while being totally ineffective against a virulent strain from the same phylotype. We tested this population against four additional RSSC strains, representing phylotypes I, IIA, IIB, and III in order to clarify the action spectrum of ERs1. We recorded wilting symptoms and bacterial stem colonization under controlled artificial inoculation. We constructed a high-density genetic map of the population using single nucleotide polymorphisms (SNPs) developed from genotyping-by-sequencing and added 168 molecular markers [amplified fragment length polymorphisms (AFLPs), simple sequence repeats (SSRs), and sequence-related amplified polymorphisms (SRAPs)] developed previously. The new linkage map based on a total of 1,035 markers was anchored on eggplant, tomato, and potato genomes. Quantitative trait locus (QTL) mapping for resistance against a total of eight RSSC strains resulted in the detection of one major phylotype-specific QTL and two broad-spectrum QTLs. The major QTL, which specifically controls three phylotype I strains, was located at the bottom of chromosome 9 and corresponded to the previously identified major gene ERs1. Five candidate R-genes were underlying this QTL, with different alleles between the parents. The two other QTLs detected on chromosomes 2 and 5 were found to be associated with partial resistance to strains of phylotypes I, IIA, III and strains of phylotypes IIA and III, respectively. Markers closely linked to these three QTLs will be crucial for breeding eggplant with broad-spectrum resistance to BW. Furthermore, our study provides an important contribution to the molecular characterization of ERs1, which was initially considered to be a major resistance gene.

“…Chapter 2 (this volume) details the sexual compatibility within the various groups of Solanaceae and Cucurbitaceae. In breeding programmes, the cultivated Solanaceae parent is usually used as the female and the wild species is the pollen donor (Bletsos et al, 1998(Bletsos et al, , 2004Premabati Devi et al, 2015), and the success of the cross is de termined by the percentage of fruit set, number of seeds per fruit and percentage germination of the F 1 seed. The hybridization barriers can act before fertilization, for example by inhibition of pollentube growth, as for Capsicum annuum L. × Capsicum pubescens Ruiz & Pav.…”

“…Seed traits are one such area for early selection: seed evaluation can be based on seed yield, seed mass, germination rate and uniformity of emergence. These seed traits tend to have high heritability, that is, a high influence of genetic factors relative to environmental factors, and ger mination of rootstock seeds takes place in protected grafting nursery conditions where the environment is controlled and has less impact on the outcomes for seed traits (Huarachi Morejon, 2013;Premabati Devi et al, 2015).…”

“…In cases where pollination has been successful, research has identified post-zygotic barriers like embryo death caused by endosperm degeneration ( Dickinson et al., 2012 ; Tonosaki et al., 2016 ); where no seed is formed and flowers abort before fruit formation ( Premabati Devi et al., 2015 ). Pollen-pistil interaction studies within the Solanaceae family have been able to categorize species as either self-compatible, self-incompatible or mutants from either ( Bedinger et al., 2011 ; Martins et al., 2015 ; Afful et al., 2018 ).…”

This has guided breeding programs in S. lycopersicum ( Baek et al., 2015 ), S. melongena ( Premabati Devi et al., 2015 ), Solanum tuberosum ( Maune et al., 2018 ) and Capsicum annum ( Jae et al., 2006 ), recording levels of crossability within and between species. Solanum aethiopicum is known to be a rich source of genes for resistance to bacterial wilt ( Collonnier et al., 2001 ), therefore hybridization studies involving it have mainly been interspecific with socio-economically and experimentally economic species like Solanum melongena and Solanum lycopersicum ( Behera and Singh, 2002 ; Afful et al., 2018 ).…”

Understanding hybridization barriers is relevant for germplasm conservation and utilization. The prezygotic barriers to hybridization include floral morphological differences like pistil and stamen length, pollen characteristics and pollen-pistil interactions. This study sought to elucidate the reproductive biology of Solanum aethiopicum; its mating systems and compatibility barriers. Eight genotypes of Solanum aethiopicum were examined for differences in floral morphology, phenology and cross compatibility in a full diallel mating design, with assessment of fruit set, seed set and seed viability. In-vivo pollen tube growth was observed for failed crosses at 24, 48 and 72 h after pollination. All genotypes had heterostyly flowers, with predominantly small white petals. Incompatibility was observed in five out of 39 combinations. All selfed genotypes displayed compatibility implying the genotypes are self-compatible. Pollen-pistil incompatibility, which was exhibited in four out of the five failed cross combinations, occurred on the stigma, upper style and lower style, a phenomenon typical in Solanaceae. Solanum aethiopicum is self-compatible and majorly self-pollinating but has features that support cross-pollination.
