Based on the literature of previous studies and characterization data available at the WorldVeg, a list of 35 crop wild relatives was included in this review, which had ~100 (S. repandum G. Solanum melongena accessions S00062, S00022, and S. aethiopicum accession S00197 exhibited high antioxidant activity (Hanson et al., 2006). Breeding for chlorogenic acid content in eggplant: interest and prospects. Replicated field trials with five Bt eggplant open-pollinated (OP) lines from transformation event EE-1 and their non-Bt comparators were conducted over three cropping seasons in the Philippines from 20102012. Daily water requirement was calculated based monthly average evaporation the results showed that total water requirement for the growth period under drip irrigation was 396.00 mm with mulch at 80 per cent ET0 level and 495.00 mm without mulch at 100 per cent ET0 level.

All three cultivated eggplant species have the Old World in origin (Figure (Figure1).1). Kranthi KR, Naidu S, Dhawad CS, Tatwawadi A, Mate K, Patil E 02534. The wild relatives of eggplant are one of the most variable and intricate groups, in regards to their taxonomic and phylogenetic relationships (Vorontsova et al., 2013). The subgenus Leptostemonum contains around 450 currently recognized species distributed worldwide (Knapp et al., 2013), many of which originated in the New World (Vorontsova and Knapp, 2012). The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. The use of high-dose/refuge strategy has been postulated to delay the potential evolution of insect resistance to the Bt crops by maintaining insect susceptibility [56]. Out of these Solanum L. is the largest one, with around 1,500 species (Frodin, 2004) including globally important crops such as potato (Solanum tuberosum L.) and tomato (Solanum lycopersicum L.), as well as many other minor crops. This line had slightly lower % efficacy for shoot damage (95.3%) and fruit damage (94.1%) but these levels were significanly much better than any of the the non-Bt comparators. 155174, In: Transgenic Horticultural Crops Challenges and Opportunities, The long road to commercialization of Bt brinjal (eggplant) in India. All sample collection and transport of materials were done under the supervision of the duly designated biosafety trial inspectors following the prescribed biosafety procedure for sample collection, handling and transport. Integration of insect-resistant genetically modified crops within IPM programs In: Romeis J, Shelton AM, Kennedy GG, editors. Although, the evidence of cultivation of eggplant in both India and China is equally old, archeological evidence suggests that utilization of wild eggplants may have started earlier in India than China, with a subsequent additional and independent center of domestication in the Philippines (Meyer et al., 2012). Data transformation was used to improve the normality of variables due to markedly skewed data or heterogeneous variances of Bt and conventional non-Bt entries. Conceived and designed the experiments: DMH RAH JON LDT MLJS FAS AMS. OPVs are standard varieties, which have stable characteristics and produce seeds that will grow into plants more or less identical to their parent plants. These accessions correspond to landraces and traditional cultivars with significant diversity in plant morphology, fruit types and colors, and resistance to biotic and abiotic stresses. More than 200 accessions have been evaluated for resistance to bacterial wilt (Ralstonia solanacearum) at the WorldVeg under both greenhouse and field conditions (AVRDC, 1999). In this respect, eggplant is ranked among the top 10 vegetables in terms of oxygen radical absorbance capacity (Cao et al., 1996). The plants of group G correspond to primitive eggplant cultivars, with small fruits, while the plants of group H are less prickly than other groups and consist of large-fruited landraces and modern cultivars (Daunay et al., 2001; Weese and Bohs, 2010; Table Table1).1). The Global Biodiversity Information Facility (GBIF) was applied to review the number of recorded occurrences, which can be natural populations, herbarium samples, or other biodiversity records (GBIF, 2017). Seeds of UPLB Bt and non-Bt eggplant entries (treatments) were sown in pots with sterilized soil 3034 days before transplanting. An official website of the United States government. 1 Mean comparison by contrast (PROC MIXED in SAS); ** highly significant at 1% probability level; mean of 4 replicates; 2 Bt = eggplant containing event EE-1; NBt = non-Bt eggplant near-isolines and commercial check; 4 Mean of total harvest periods: Trial 1 (9 harvests); Trial 2 (13 harvests); Trial 3 (9 harvests), 5 Mean of total harvest periods: Trial 1 (9 harvests); Trial 2 (13 harvests); Trial 3 (9 harvests). Seedlings of Bt and non-Bt eggplant test entries, check varieties and pollen traps were transported from UP Los Baos to the confined field testing site in Bgy. Several major maize and cotton pests have been successfully controlled, and insecticide use on them has been substantially reduced throughout most adopting countries [3]. Access to genetic diversity is fundamental for any breeding program. A 200-meter radial distance isolated the field trial site from the nearest eggplants in the area. (2012). Recent reviews of the development in eggplant is provided by Frary and Doganlar (2013) and Gramazio et al. In the southeastern United States, eggplant is often produced with high levels of irrigation water [above the rate of crop evapotranspiration (ETc)], resulting in water waste and nitrogen (N) leaching. Sorry, preview is currently unavailable. Although, not all national genebanks report to Genesys, we still used the information for reviewing global holdings. All field trials were conducted in accordance with the Department of Agriculture Administrative Order No. Host plant resistance can be measured as a percentage of damage to the foliage or fruiting parts, reduced crop stand, yield and vigor [53]. Wild eggplants produce small, bitter, multi-seeded fruits, almost always inedible, and the plant is generally very spiny. Standardized descriptors included characters both for germination, the vegetative phase, inflorescence descriptors, and fruit and seed traits, respectively (Table (Table55). indicum L. should be determined, as this name was rejected in 1978 as it was used to refer to two clearly distinct species, the African S. anguivi and the Asian S. violaceum (Vorontsova and Knapp, 2016). Even under the most severe pest pressure during trial 2, the Bt eggplant lines demonstrated high level of control of EFSB shoot damage (98.6100%) and fruit damage (98.199.7%) and reduced EFSB larvae infestation (95.899.3%).

Thus, they take notes and then put the information in their own words for the draft. HS726/CV124: Chapter 8. Eggplant Production - EDIS Indeed, there is a need for conducting collection missions and conservation actions for eggplant wild relatives (Conservation gaps, http://www.cwrdiversity.org/conservation-gaps/, Accessed February 30, 2017). and transmitted securely. n = 4 per growth stage/line with 510 plants per replicate plot. Farmers in Pangasinan plant eggplant after rice starting in the months of September to October (planting season) and harvest during the months of December to April. Grafting is increasingly becoming an indispensable tool that minimizes the risks associated with intensive vegetable production systems, including soil-borne diseases. High yielding, small sized fruits with a slightly bitter taste preferred by consumers. Terminal leaves were collected at the vegetative (up to 25 days after transplanting, DAT), reproductive (2560 DAT) and late reproductive (6080 DAT) stages of the crop. Finally, environmental factors could have contributed to the spatio-temporal expression of the Cry1Ac protein in Bt eggplant lines. Cheramy. Brinjal eggplant (Solanum melongena L.) is a warm-weather crop mostly cultivated in tropical and subtropical regions of the world. The number of surviving EFSB larvae found inside the fruits per replicate plot were recorded every harvest period. Five promising advanced Bt OP lines, developed by the University of the Philippines Los Baos, were selected for Confined Field Trial testing in selected eggplant growing areas of the country. AVRDC Publication No. In another study conducted at the WorldVeg, 33 S. melongena accessions and two S. aethiopicum accessions were evaluated for superoxide scavenging and content of total phenolics and ascorbic acid (Hanson et al., 2006).

In Bt cotton, Cry1Ac protein levels were generally high at early stages and then declined as the plant grew to maturity [31, 43]. Confined field trial 1 (wet/off season) and trial 2 (dry season), CY 20102011, Pangasinan, Philippines. CY 201012, Sta. There were no significant differences in Cry1Ac protein expression in either the fruit flesh or the skin among the Bt eggplant lines tested in both trials. This study assesses the performance of two cherry tomato hybrids (Cheramy and Sheeja) grafted onto three tomato and five eggplant local rootstock genotypes (cultivated/wild) under Ralstonia solanacearum (bacterial wilt)-infested greenhouse soil. Eggplant (Solanum melongena L.) is one of the most important vegetable in the world after potato, tomato and cucumber and it is usually grown for its nutritious fruits which are utilized as vegetables to contribute to the essential nutrients in human diet (Maghfoer et al., 2013). Young frits are also eaten raw. The WorldVeg plays a major role in the conservation and distribution of vegetable germplasm, holding 60,387 accessions comprising 173 genera and 440 species from 151 countries of origin (AVGRIS, 2017). The confined field trials were managed based on the national cooperative trial guidelines for eggplant [59] and prevalent agronomic practices for eggplant growing in the region, including site preparation, tillage, and nutrient applications. Genotype environment interactions in eggplant for fruit phenolic acid content. Chiarini F. E., Moreno N. C., Barboza G. E., Bernardello G. (2010). Association mapping for fruit, plant and leaf morphology traits in eggplant. The larvae damage eggplant by boring into the petiole and midrib of leaves and tender shoots resulting in wilting and desiccation of stems. The studies were conducted in a comparative manner. Field trials documented levels of Cry1Ac protein expressed in plants and evaluated their efficacy against the primary target pest, EFSB. Ranil R. H., Prohens J., Aubriot X., Niran H. M., Plazas M., Fonseka R. M., et al. The Bureau of Plant Industry (BPI) issued the corresponding Biosafety Permit for Field Testing in Bgy. Bethesda, MD 20894, Web Policies We sincerely thank the following Bt eggplant staff for their various valuable contributions: OO Silvestre, MMM Abustan, RN Candano, RP Urriza, ER Maligalig, SA Baldo and MM Marin for field establishment and management and lab/field data collection; RR Ripalda, RB Frankie, ML de Vera and AD Austral for sampling and Cry1Ac analysis; and ZJ Bugnosen for assistance in regulatory-related and administrative activities. The highest level of Cry1Ac protein expressed in the roots was 2.64 ppm DW. In this study, significant differences were detected in the amount of Cry1Ac expressed in different plant parts: terminal leaves > flowers > fruits > stem > roots. Weather data obtained during the duration of the two trials indicated that the average daily temperature was similar but the amount of rainfall was much higher in trial 1 than trial 2. Phylogenetic relationships among the spiny solanums (. Comparison of eggplant landraces and commercial varieties for fruit content of phenolics, minerals, dry matter and protein, Insect and Mite Pests on Eggplant: A Field Guide for Indentification and Management. However, additional race specific screening is needed to find resistant sources for pests where no resistance or limited resistance has been found. The distribution of dry matter, total sugar, and fiber contents ranged from 5.5 to 10.1, 7.0 to 40.1, and 4.7 to 18.1%, respectively. However, the widest range of variation was observed between the two trials. As a point of departure, we examine the taxonomy and relationships of the crop and its wild relatives, as well as the domestication of cultivated eggplant. In this study, variability in Cry1Ac protein expression in the Bt eggplant lines could also be attributed to using the constitutive 35S CaMV promoter in the EE-1 gene construct, as suggested in studies with Bt cotton which used the same promoter. of leaf prickles on upper surface of the leaf), 0 = None, 1 = Very few (12), 3 = Few (35), 5 = Intermediate (610), 7 = Many (1120), 9 = Very many (>20), X = Mixture, 1 = Very few (<20), 3 = Few (2050), 5 = Intermediate (50100), 7 = Many (100200), 9 = Very many (>200), X = Mixture, Number of days from sowing until first flower opening (, Number of hermaphrodite flowers per inflorescence, 1 = One, 2 = Two, 3 = Three, 4 = Four or more but some flowers functionally male, 5 = Four or more, no functionally male, X = Mixture, 0 = Yellow, 1 = Greenish white, 3 = White, 5 = Pale violet, 7 = Light violet, 9 = Bluish violet, X = Mixture, 3 = Short (~1), 5 = Intermediate (~3), 7 = Long (~5), X = Mixture, 0 = None, 3 = Low, 5 = Medium, 7 = High, X = Mixture, 3 = Inserted, 5 = Intermediate, 7 = Exerted, X = Mixture, Fruit length from base of calyx to tip of fruit (cm), 1 = Very short (<1), 3 = Short (~2), 5 = Intermediate (~5), 7 = Long (~10), 9 = Very long (>20), X = Mixture, Fruit breadth diameter at broadest part (cm), 1 = Very small (<1), 3 = Small (~2), 5 = Intermediate (~3), 7 = Large (~5), 9 = Very large (>10), X = Mixture, 1 = Broader than long, 3 = As long as broad, 5 = Slightly longer than broad, 7 = Twice as long as broad, 8 = Three times as long as broad, 9 = Several times as long as broad, X = Mixture, 1 = None, 3 = Slightly curved, 5 = Curved, 7 = Snake shaped, 8 = Sickle shaped, 9 = U shaped, X = Mixture, 1 = Very short (<5), 3 = Short (~10), 5 = Intermediate (~25), 7 = Long (~50), 9 = Very long (~75), X = Mixture, 1 = Very thin (<1), 3 = Thin (~2), 5 = Intermediate (~3), 7 = Thick (~5), 9 = Very thick (>10), X = Mixture, 0 = None, 1 = Very few (<3), 3 = Few (~5), 5 = Intermediate (~10), 7 = Many (~20), 9 = Very many (>30), X = Mixture, 3 = About 1/4 way from base to tip, 5 = About 1/2 way from base to tip, 7 = About 3/4 way from base to tip, X = Mixture, 3 = Protruded, 5 = Rounded, 7 = Depressed, X = Mixture, 1 = Green, 2 = Milk white, 3 = Deep yellow, 4 = Fire red, 5 = Scarlet red, 6 = Lilac gray, 7 = Purple, 8 = Purple black, 9 = Black, X = Mixture, Fruit color distribution at commercial ripeness, 1 = Uniform, 3 = Mottled, 5 = Netted, 7 = Striped, X = Mixture, 1 = Green, 2 = Deep yellow, 3 = Yellow orange, 4 = Deep orange, 5 = Fired red, 6 = Poppy red, 7 = Scarlet red, 8 = Light brown, 9 = Black, X = Mixture, 1 = Erect, 3 = Semi-erect, 5 = Horizontal, 7 = Semi-pendant, 9 = Pendant, X = Mixture, 1 = Circular, no grooves, 3 = Elliptic, no grooves, 5 = Few grooves (~4), 7 = Many grooves (~8), 9 = Very irregular, X = Mixture, 1 = Very loose (spongy), 3 = Loose (crumbly), 5 = Average density, 7 = Dense, 9 = Very dense, X = Mixture, 1 = Very low (<250), 3 = Low (~500), 5 = Intermediate (~1,000), 7 = High (~2,500), 9 = Very high (>5,000), X = Mixture, 3 = Bitter, 5 = Intermediate, 7 = Sweet, X = Mixture, 0 = Pure, 3 = Slight mixture, 5 = Medium mixture, 7 = Serious mixture, 1 = 01 min, 2 = 13 min, 3 = 35 min, 4 = 57 min, 5 = 79 min, 6 = 912 min, 7 = 1215 min, 8 = 1520 min, 9 = 2030 min, 10 = 30 min or more, 1 = White, 2 = Light yellow, 3 = Grey yellow, 4 = Brownish yellow, 5 = Brown, 6 = Brown black, 9 = Black, X = Mixture, 0 = None, 1 = Very few (<10), 3 = Few (~50), 5 = Intermediate (~100), 7 = Many (~300), 9 = Very many (>500), X = Mixture, 3 = Scarce, 5 = Intermediate, 7 = Dense, X = Mixture, 3 = Small (~2), 5 = Intermediate (~3), 7 = Large (~4), X = Mixture, 1 = Bulk, 2 = 2 sub-accessions, 3 = 3 sub-accessions, Resistance to eggplant fruit and shoot borer (. Residues of these insecticides were detected in the soil of eggplant farms and in harvested fruits [14]. A Sicilian-style eggplant with a round, heavy, firm fruit, deep-purple color, sweet taste, and white flesh.

High yielding with a slightly bitter taste preferred by consumers. Confined field trial1 (wet/off season) and trial 2 (dry season), CY 20102011, Pangasinan, Philippines. The three cultivated species are indicated with an asterisk. Accessibility The average moult inhibitory concentration, MIC95, from 29 L. orbonalis populations tested for Cry1Ac was 0.059 ppm [21,28]. Cost benefit ratio analysis indicates the profitability of eggplant cultivation at 10 t ha-1 goat manure compared to other manure source and rates of application. Giza, Egypt, 3Faculty of Applied Ecology and Agricultural Sciences, Inland Norway University of Applied Sciences, Stems and roots were washed prior to storage. The field efficacy of Bt eggplant lines, measured as % EFSB-damaged shoots, also remained very high (95.4100% reduction) during the entire 10 weeks of evaluation. [25]. larvae/plot)All harvested fruits from the 16 inner row plants per were cut open to check for the presence of EFSB larvae. The Pangasinan field trial site represented the conditions in small-holder farmers fields that experience very high natural incidence of EFSB pressure compared with other trial sites. Accessions VI034971, VI035822, and VI035835 were found promising accessions against leafhopper and aphids. The Global Gateway to Genetic Resources (GENESYS, 2017) was applied to review the number of conserved genebank accessions. Quantification of Cry1Ac was done through an enzyme-linked immunosorbent assay (ELISA). The site is secure. In this study, seasonal variation was also detected in the level of Cry1Ac protein expression in the terminal leaves of Bt eggplant lines.
