“…Obtaining more eggplant drought-tolerant cultivars depends on the identification of germplasm of interest and the introgression of relevant genes. Both steps require efficient, fast, and preferably inexpensive methods [ 15 , 16 , 17 ]. With the development of new generations of cultivars with introgressed genes providing tolerance, higher yields could ultimately be obtained in the face of climate change effects.…”

In a climate change scenario, crop tolerance to drought must be urgently improved, as it represents an increasingly critical stress reducing agricultural yields worldwide. Although most crops are relatively sensitive to water stress, many of their wild relatives are more tolerant and may be used to improve drought tolerance in our crops. In this study, the response to drought of eggplant (Solanum melongena), its close wild relatives S. insanum and S. incanum and their interspecific hybrids with S. melongena was assessed. The plants were subjected to two treatments for 18 days: control, with irrigation every four days, and drought, with complete interruption of irrigation. Morphological and biomass traits were measured, and physiological and biochemical responses were analysed using stress biomarkers such as proline, flavonoids, and total phenolic compounds. Oxidative stress was quantified by measuring malondialdehyde (MDA) content. As a result of the drought treatment, plant development and tissue water content were seriously affected. Generally, water deficit also caused significant increases in MDA, proline, flavonoids, and total phenolics compounds. Our results comparing parental accessions reveal a better response to drought in one of the S. insanum accessions. The hybrid between S. melongena and S. incanum displayed a better response than the other hybrids and even its parents. The results obtained here might be helpful for future eggplant breeding programmes aimed at improving drought tolerance.

“…On the other hand, fruits of 'Amedo' significantly exceeded all other cultivars in their content of vitamin C, niacin and omega 3. According to Oladosu et al (2021) the amount of niacin in eggplant fruits is 0.649 mg/100 g DW. Whitley et al (2011) detected significant differences among the different peanut varieties in niacin concentrations, being ranged from 13.9 to 20.7 mg/100g DW.…”

Two experiments were conducted during the two winter seasons of 2018/2019 and 2019/2020 at the Agricultural Experimental Station of Faculty of Agriculture Cairo University Giza to investigate the response of four spherical F1 cultivars (Sawad El Laiel, Petra, Amedo and Black Berry) of eggplant (Solanum melongena L.) under two different production systems (open field and plastic house), consider the vegetative growth, fruit quality and yield. Plants grown in open field had higher values of number of branches, early and total yield, fruit weight, fruit diameter, fruit total carbohydrate, vitamin C, macro and micro elements and significant increase in leaf dry matter, leaf concentrations of macro and microelements compared with plastic house production. Reversely, planting in plastic house significantly increased plant height, leaf area and fruit dry matter compared with planting in open field. The period from transplanting to first harvest was shorter in plants grown in open field than those grown in plastic house. Meanwhile, there were no significant differences between production systems in leaf chlorophyll, fruit length, fruit contents of TSS, Ca, Mg, niacin and omega3 in both seasons. The analysis showed significant differences among the different eggplant cultivars for all traits. Sawad El Laiel' recorded the highest value of early and total yield, average fruit weight, total carbohydrate, TSS and leaf concentrations of K, Ca and B. On the other hand, 'Amedo' significantly exceeded all other cultivars in chlorophyll reading and leaf concentrations of N, P, Mg, Fe, Mn and Zn as well as fruit diameter, fruit concentrations of N, P, K, Ca, Mg, Fe, Mn, Zn, vitamin C, niacin (B3) Omega 3 and dry matter. 'Petra' was the earliest cultivar, while the 'Black Berry' was the latest one. The interaction between cultivars and production systems had significantly influence on all traits under study.

“…Eggplant (Solanum melongena L.) is a warm-weather crop and one of the most important vegetable crops worldwide, especially in Africa, subtropical regions, Southeast Asia and the Middle East (FAO, 2017, Chapman, 2019. Eggplant fruit is a rich source of vitamins, essential minerals and some bioactive compounds that have beneficial properties for human health as well as a low caloric value (Kowalski et al, 2003, Oladosu et al, 2021. It is also one of Egypt's most economically important vegetable crops, ranking fourth in the Solanaceae family after tomato, potato, and pepper.…”

T HIS study was undertaken to evaluate the field performance of the two newly promising bred eggplant F 1 hybrids (H1 and H2) relative to a commercial eggplant hybrid (Alabaster, C4) as a reference, as well as apply a dependable DNA fingerprinting technique (PCR-based, Inter Simple Sequence Repeat, ISSR markers) for identification and documentation of locally produced eggplant F 1 hybrids. Vegetative growth and yield parameters for H1, H2, and C4 eggplant hybrids were evaluated under four ecological conditions and in different geographic governorate locations (Giza "L-1", Menofia "L-2", Qalyubia "L-3" and El-Behaira "L-4") during the two growing seasons of 2020 and 2021 The means of locally produced eggplant F 1 hybrids (H1 and H2) exceeded or equaled the means of the reference hybrid (C4), especially under the conditions of Qalyubia (L3) and Giza (L1) for the characteristics of plant height, number of branches/plant, number of leaves/plant, early flowering, early fruit yield, total fruit yield, number of fruits/plant and the average fruit weight. Furthermore, nineteen ISSR primers were used to identify the genetic fingerprint of the above-mentioned hybrids (H1, H2 and C4) in addition to two local parental lines (P1 and P2). ISSR analysis revealed 243 distinct DNA amplified bands with polymorphic bands of 50.21%. The percentage of polymorphism ranged between 9% and 88% with an average level of 50%. The PIC value varied from 0.09 to 0.49 with an average of 0.36. Seven ISSR primers (HB12, 17899-A, UBC-844, UBC-892, UBC-895, ISSR-59 and ISSR-DAT) produced distinctive fingerprints associated with H1 hybrid. In the same context, eight primers (HB10, HB12, UBC-892, UBC-808, ISSR-55, ISSR-01, ISSR-59 and ISSR-DAT) were distinctive for H2 hybrid. While the commercial hybrid "C4" was distinguished by only three primers (UBC-850, UBC-881 and ISSR-9). The highest similarity value of 0.89 was found between P1 and H1, while the lowest value of 0.78 between P1 and H2. It may be concluded that local eggplant hybrids (H1 and H2) performed superiorly in most studied traits and displayed more polymorphisms than the commercial eggplant hybrid "C4".
