“…Although, Solanum aethiopicum gr. gilo is a close relative species of S. melongena [16], from our results it appears that graft incompatibility might exist especially when 'Scarlatti' is grafted onto S. aethiopicum gr. gilo accession 2.…”

“…Since scarlet eggplant is a cultivated species, it does not display those undesirable traits that are commonly present in the wild relatives of eggplant such as small fruit production, presence of prickles, and high saponins and glycoalcaloids concentrations [15]. A great genetic and morphological variability has been evidenced in S. aethiopicum [16]; therefore, it is particularly relevant to characterize the accessions for the presence and expressivity of the traits of interest before starting a breeding program. Interspecific sexual and somatic hybrids between S. melongena and S. aethiopicum gr.…”

Solanum aethiopicum gr. gilo and Its Interspecific Hybrid with S. melongena as Alternative Rootstocks for Eggplant: Effects on Vigor, Yield, and Fruit Physicochemical Properties of Cultivar ′Scarlatti′

Grafting is generally considered effective in ameliorating vegetable crop tolerance to biotic and abiotic stresses. The use of interspecific hybrid as rootstock for eggplant may represent a valid alternative approach to enhance eggplant performance. However, studies on the effects of different rootstocks on eggplant plant vigor, yield, and fruit quality traits often show conflicting results. Thus, an experiment was performed in two spring–summer growing seasons (2014 and 2015) by grafting eggplant ′Scarlatti′ F1 hybrid on two accessions of S. aethiopicum gr. gilo and on the interspecific hybrid S. melongena × S. aehtiopicumgr. gilo in comparison to the most common eggplant rootstock S. torvum. Results indicate that S. melongena × S. aethiopicum gr. gilo interspecific hybrid and S. torvum improved grafting success, plant vigor, early flowering and yield in ′Scarlatti′ F1 scion. All rootstocks tested did not negatively influence fruit apparent quality traits and fruit quality composition. Moreover, fruit glycoalkaloids content remained below the recommended threshold value. These findings suggest that the use of S. melongena × S. aethiopicum gr. gilo interspecific hybrid as rootstock may be a good alternative to the most commonly used S. torvum.

“…Hundred normal seeds of each accession were sowed in separated nursery bags loaded with ordinary sand and labelled. Transplanting of the seedlings was carried out at the 5 to 6 leaf stage following the recommendations of Segnou et al (2012) adopted by Sawadogo et al (2016). The randomized complete block design with 3 replications was used with regard to the high number of accessions and to control the high level of land heterogeneity conditions in Massi.…”

“…Scarlet eggplant is known for its great morphological variability. Three cultivated groups (Gilo, Shum, and Kumba) having distinct morphological traits were found in some West-African countries such as Nigeria (Adeniji et al, 2019), Burkina Faso (Bationo-Kando et al, 2015;Sawadogo et al, 2016), Côte d'Ivoire (Kouassi et al, 2014), and Ghana (Osei et al, 2010). However, except for some studies mentioning the presence of Gilo and Shum groups in the Beninese agriculture (Achigan-Dako et al, 2010), very little information exist on the diversity of scarlet eggplant throughout the country.…”

The scarlet eggplant (Solanum aethiopicum L.) is an African traditional vegetable grown for its edibles leaves and fruits, which can contribute to food security in Republic of Benin. However, very little information is available on the genetic variability of this vegetable for varietal improvement purposes. Sixty accessions of scarlet eggplants collected throughout 52 villages in Benin republic were characterized using 34 (10 qualitative and 24 quantitative) variables. The experiment was laid out using complete randomized block design with three replications on the experimental site of Massi. The Principal Component Analysis (PCA) analysis revealed 18 discriminating quantitative variables. A strong correlation was observed between plant height, number of fruits per plant, fruit diameter, fruit weight and number of seeds per fruit. A cluster phenogram divided the 60 accessions into three groups corresponding to Kumba (Cluster 1), Gilo (Cluster 2), and Shum groups (Cluster 3). These groups differed by the number of seeds per fruit, weight of fruits, diameter of fruits, number of fruits per plant, plants height at flowering stage, plants length, and plant width. Accessions Samibi, Ikangougou, Kannan and Yètchanmiyé with the highest fruit weight per plant can be used as parents in the framework of a scarlet eggplant breeding program in Republic of Benin.

African eggplant (Solanum aethiopicum L.) is an important vegetable grown for it leaves and fruits in tropical regions. At Burkina Faso, Kumba group is widely used for food and traditional physic. It's also income source for majority population. Despite, its socioeconomic importance, there is a few scientific knowledge on its genetic diversity. The objective of this study is to evaluate genetic diversity of Kumba group. For this, a molecular characterization of forty-nine (49) accessions collected in the three climatic zones was carried out. The analysis of diversity used EST-SSRs molecular markers revealed moderate genetic variability within the collection, structured into three molecular groups. Indeed, 19 of the 29 markers tested were polymorphic. Expected heterozygosity (H e ) for the all collection ranged from 0.075 for smSSR41 marker to 0.507 for smSSR27 and smSSR35 markers. The Shannon diversity index (I), it ranged from 0.163 for smSSR41 marker to 1.307 for smSSR09 marker. The organization of this genetic diversity is weakly influenced by the climatic zone.
