“…The increased yield in the early harvest stages indicated that the application of SES shortened the fruitripening time (days from anthesis to ripening) of tomato. 31 The photos taken on 21 January 2018 further confirmed the results as more fully ripe red tomatoes existed on the plants applied with SES ( Figure 1). Seaweed extracts contain cytokinins, 23,24 auxins, 25 and ABA-like growth substances 10 and these hormonal substances have been shown to have a stimulatory effect on plant growth and fruit maturity.…”

Overuse of chemical fertilizers in the intensive greenhouse tomato cultivation system has limited the increase of plant production. Nowadays, seaweed extract has been gradually applied in agriculture as an effective way to achieve a higher yield of crops, but its effects on tomato cultivation have not been fully explored. In this study, a greenhouse experiment was conducted in Shandong province of China with a novel seaweed extract (SES) originated from Sargassum horneri, to investigate the effects of different doses of SES (0, 30, 60, and 90 kg hm −2 ) on yields, quality, ripening time, and net returns of tomato. The results indicated that the application of SES significantly increased tomato yield by 4.6−6.9% compared to the control, which is attributed to the improved photosynthetic capacity of tomato leaves. The yields of tomato increased first and then decreased with increasing dosage of SES, and SES applied at the dose of 60 kg hm −2 achieved the highest tomato yield. Compared to the control, SES at 60 and 90 kg hm −2 significantly increased the hardness of tomato by 10.2 and 19.8%, respectively, and this can help to reduce losses during transportation and storage. Moreover, SES shortened the ripening time of tomato, and the coincidence between tomato harvest and sale price peak achieved a high net return.See https://pubs.acs.org/sharingguidelines for options on how to legitimately share published articles.a Mean values followed by the same lowercase letter were not significantly different at the 0.05 probability level based on one-way analyses of variance (ANOVAs) followed by Duncan's multiple range tests within the same column.

“…To our knowledge, so far, in spite of that most of the studies on the genetic basis of the plant fruit traits have been focused on tomato (Alpert et al 1995;Grandillo et al 1999;Doganlar et al 2000;Knaap and Tanksley 2001;Causse et al 2007), still there were several studies contributing to cucumber, particularly, by Staub's laboratory (Kennard and Havey 1995;Serquen et al 1997;Dijkhuizen and Staub 2002;Fazio et al, 2003a). In 2007, we mapped the QTLs for nine cucumber fruit related traits (FW, FL, FD, FFT, SCD, FSL, FPL, LDR and LSR) with two fresh-eaten cucumber types ).…”

A set of 224 recombinant inbred lines (RILs) derived from a narrow cross between two fresh eaten types (S94 (Northern China type) 9 S06 (Northern European type)) (Cucumis sativus L.) was used to construct a genetic linkage map. With the RILs a 257-point genetic map was constructed including 206 SRAPs, 22 SSRs, 25 SCARs, 1 STS, and three economically important morphological markers (small spines (ss), uniform immature fruit color (u), dull fruit skin (D)). The seven linkage groups covered 1005.9 cM with a mean marker interval of 3.9 cM.The ss locus was linked to D and u, and they were all on Linkage group 6. The RIL map contained a total of 51 sequence-specific markers, which made possible the comparison of molecular linkage maps developed in different laboratories. Using the F 6:7 derived families, a total of 78 QTLs were detected with relatively high LOD scores (2.9-84.4) for nine fruit-related traits (fruit weight, length, and diameter, fruit flesh thickness, seed-cavity diameter, fruit-stalk length, fruit pedicel length, length/diameter and length/stalk ratio) and three flower-related traits (first flower node, first female flower node and female flower ratios). Several sequence-anchor markers (CSWCT25, CS30, CMBR41, CS08 etc.) were closely linked with some QTLs for fruit weight, fruit length, fruit flesh thickness and sex expression, which can be used for the future marker-assisted selection to improve the fruit traits in cucumber breeding.

“…To date, many QTL identification and mapping studies have been conducted on balanced populations in which both parental alleles are in high frequency, such as backcrosses, F 2 s, recombinant inbred lines, or doubled haploids (e.g., Stuber et al 1992;deVicente and Tanksley 1993;Azanza et al 1994;Xiao et al 1996;Doganlar et al 1999). Using balanced populations allows efficient determination of the chromosomal positions of each QTL, estimation of the minimal number of QTL affecting a trait of interest, as well as definition of the relative contribution of each QTL to the expression of the trait of interest.…”

Although tomato has been the subject of extensive quantitative trait loci (QTLs) mapping experiments, most of this work has been conducted on transient populations (e.g., F 2 or backcross) and few homozygous, permanent mapping populations are available. To help remedy this situation, we have developed a set of inbred backcross lines (IBLs) from the interspecific cross between Lycopersicon esculentum cv. E6203 and L. pimpinellifolium (LA1589). A total of 170 BC 2 F 1 plants were selfed for five generations to create a set of homozygous BC 2 F 6 lines by single-seed descent. These lines were then genotyped for 127 marker loci covering the entire tomato genome. These IBLs were evaluated for 22 quantitative traits. In all, 71 significant QTLs were identified, 15% (11/71) of which mapped to the same chromosomal positions as QTLs identified in earlier studies using the same cross. For 48% (34/71) of the detected QTLs, the wild allele was associated with improved agronomic performance. A number of new QTLs were identified including several of significant agronomic importance for tomato production: fruit shape, firmness, fruit color, scar size, seed and flower number, leaf curliness, plant growth, fertility, and flowering time. To improve the utility of the IBL population, a subset of 100 lines giving the most uniform genome coverage and map resolution was selected using a randomized greedy algorithm as implemented in the software package MapPop (http://www.bio.unc.edu/faculty/vision/lab/ mappop/). The map, phenotypic data, and seeds for the IBL population are publicly available (http://soldb.cit.cornell.edu) and will provide tomato geneticists and breeders with a genetic resource for mapping, gene discovery, and breeding.Key words: tomato, Lycopersicon esculentum, IBLs, QTL, mapping.Résumé : Bien que la tomate ait été l'objet de nombreuses études de cartographie des loci de caratère quantitatif (QTL), la plupart de ces travaux ont été réalisés sur des populations non-fixées (F 2 ou rétrocroisement) et peu de populations homozygotes, permanentes sont disponibles. Afin de remédier à cette situation, les auteurs ont développé une collection de lignées rétrocroisées fixées (« inbred backcross lines », IBL) à partir d'un croisement interspécifique entre le Lycopersicon esculentum cv. E6203 et le L. pimpinellifolium (LA1589). Cent soixante-dix plants BC 2 F 1 ont été reproduits par descendance monosporale pendant cinq générations pour produire des lignées BC 2 F 6 homozygotes. Ces lignées ont ensuite été génotypées à l'aide de 127 locus marqueurs couvrant l'ensemble du génome de la tomate. Ces IBL ont été évaluées pour 22 caractères quantitatifs. Au total, 71 QTL significatifs ont été identifiés, dont 15 % (11/71) étaient situés à la même position chromosomique que lors d'études antérieures faisant appel à ce même croisement. Pour 48 % (34/71) des locus détectés, l'allèle sauvage était associé à une performance agronomique améliorée. Plusieurs nouveaux QTL ont été identifiés dont plusieurs de grande importance agro...
