This research aimed to assess the salt tolerance of soybean genotypes by evaluating seed germination at varying salt concentrations (100 mM, 150 mM, and 200 mM NaCl) from two seed source locations. A total of 198 soybean genotypes were analyzed post-germination using 10 quantitative traits: germination percentage, seedling fresh weight, seedling dry weight, seedling length, shoot length, root length, seedling vigor index-1, seedling vigor index-2, seedling water content, and salt tolerance. Analysis of variance (ANOVA) results indicated significant differences among treatments across both locations. Principal component analysis revealed that certain quantitative traits were more prominent at different salt concentrations, thus confirming varied responses to salt stress. Correlation analysis demonstrated a positive relationship between germination percentages and growth parameters such as fresh weight, dry weight, and vigor index. The study observed a decline in all quantitative traits as salt concentration increased, highlighting the stress experienced by plants during germination and growth under high salinity conditions. Using K-means clustering, the 198 genotypes were categorized into tolerant, moderately tolerant, moderately susceptible, and susceptible groups. This clustering helped identify genotypes exhibiting high tolerance (≥ 80% germination at 200 mM NaCl) and high susceptibility (≤ 40% germination at 100 mM NaCl) consistently across both seed source locations. Consequently, seven salt-tolerant genotypes (MACS 708, KALITUR, MACS 1037, IC 13050, MACS 1010, PK 1029, and MACS 173) and three salt-sensitive genotypes (HIMSO 1563, EC 391181, and EC 241920) were identified, providing new insights into soybean cultivation under saline conditions.","PeriodicalId":12467,"journal":{"name":"Genetic Resources and Crop Evolution","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141884876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the greater genetic variation present in wild genotypes, there is an increased possibility of possessing the desired features. The objective of this study was to determine the genetic diversity and population genetic structure of 64 grapevine genotypes using inter-primer binding site (iPBS) retrotransposon markers and simple sequence repeat (SSR) markers. A total of 236 bands were generated using iPBS markers, of which 162 bands exhibited polymorphism. A comprehensive assessment was conducted on a total of 126 SSR alleles using the SSR markers, revealing that 91 of these exhibited polymorphisms. Despite the similarity in mean values between polymorphic bands generated by iPBS (6.48) and SSR markers (6.5), the iPBS markers exhibited a greater polymorphism information content (PIC: 0.39) in comparison to SSR markers (0.29). The UPGMA analysis classified the genotypes into two primary groups at a similarity index of 0.62 based on combined data. The rootstocks utilized as points of reference are consolidated inside a singular cluster (A), distinct from both the Mediterranean wild population and cultivars. The comparison of genetic variation, represented by FST values, revealed that the maximum differentiation was observed between subpopulations SP3 and SP5. The wild grapevine population grown in the Southeast Mediterranean Region of Turkey exhibited significant differentiation. Both marker systems employed in this study were highly polymorphic and useful for genetic characterization and mapping of grapevine populations.","PeriodicalId":12467,"journal":{"name":"Genetic Resources and Crop Evolution","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141884874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the current global warming and challenges in agriculture and food production, increasing attention must be given to these crop wild species as they can provide genetic resources that may be helpful to address some of the current challenges in agriculture (e.g., adaptation to drought). In this study, we compared the morpho-physiological performances of Solanum macrocarpon and its wild relative Solanum sisymbriifolium under different watering conditions in Benin. Seedlings were grown in plastic pots under shade-house and subjected to low, moderate, and high-water supply (i.e., 25%, 50% and 75%, respectively of the pot holding capacity). Parameters related to seedlings growth, biomass allocation and stomatal density were investigated. Descriptive statistics and linear mixed effect models were used for data analysis. Results revealed highly significant differences of morpho-physiological parameters between wild and cultivated Solanum species along the watering gradient. First, seedlings from the wild relative demonstrated higher morphological growth parameters than seedlings of the cultivated species irrespective of the watering level. Second, the wild relative also showed better performances in terms of biomass allocation and number of stomata, regardless of leaves faces and watering level than the cultivated species. Water stress reduced values of morpho-physiological parameters for both wild and cultivated species. Contrary to our expectations, the wild relative instead of being resistant, was found to also be sensitive to water stress. However, it was found to be more tolerant to drought than the cultivated species, and therefore could be considered when selecting rootstocks for crop improvement.","PeriodicalId":12467,"journal":{"name":"Genetic Resources and Crop Evolution","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Commercial cultivars, almost all Asian rice, are mostly selected for high yields. Traditional landraces are often selected for different traits, such as time to maturity or resistance against common stress factors, including bird attacks and poor soils. Maroons, descendants of enslaved Africans in Suriname and French Guiana, cultivate a rich diversity of rice landraces. They categorize landraces into short, medium, and long-maturation and maintain that fast-ripening crops with moderate yields facilitated their flight from enslavement, while once settled in a safe place, there was time for landraces with longer ripening periods and higher yields. Previous authors assumed that all Maroon landraces had low yields (700–1000 kg/ha), but their performance in traditional farming systems had never been investigated. We followed the growth and harvest of 28 Maroon rice landraces and two commercial cultivars in Maroon farmer fields, using traditional farming methods, at three locations. We show that, in farmer-managed fields, Maroon rice can yield 2600 kg/ha (average 1665 kg/ha), without any agrochemicals or machinery. Contrastingly, the commercial cultivars in Maroon farmer fields had a low yield (625–1205 kg/ha), partly due to bird predation. The maturation time varied between 110 and 183 days, but the three Maroon maturation categories showed significant overlap. Our study indicates that Maroon rice performance can only be fairly evaluated if measurements are taken in traditional Maroon farming systems, since this is the environment in which these landraces were originally selected.","PeriodicalId":12467,"journal":{"name":"Genetic Resources and Crop Evolution","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 10 pairs of simple sequence repeat (SSR) primers amplified a total of 137 clearly identifiable loci, with an average of 13.7 loci per marker. The mean values of observed number of alleles (Na), effective number of alleles (Ne), Nei’s diversity index (H), Shannon’s information index (I), and polymorphism information content (PIC) of the primers were 1.997, 1.295, 0.197, 0.327, and 0.504, respectively. Genetic relationship analysis was performed by principal coordinate analysis (PCoA) and neighbour-joining cluster analysis (NJ) to classify germplasm into 3 and 11 groups. Germplasm from different regions was interspersed in the groups, suggesting that there was also a certain degree of kinship between germplasm resources from different regions. All germplasms were divided into two populations by structural analysis, and there was low genetic differentiation between them, suggesting relatively narrow resource utilization and a relatively low genetic base of cultivars in breeding units over time. The above results indicated that the DNA clustering of walnut germplasm is not related to its geographical origin but rather to its genetic relationship, suggesting the complexity of the genetic background of walnut germplasm. These findings provide a theoretical basis for further rational use of walnut germplasm resources and for breeding new walnut cultivars with exceptional traits.","PeriodicalId":12467,"journal":{"name":"Genetic Resources and Crop Evolution","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Native to the New World, pitahayas are considered underutilized crops with nutraceutical properties and easily propagated with a distribution that could potentially be extended to dry climates. Our goal is to understand the relationships of wild and cultivated populations and to determine genetic variation in a spatial scenario to discover hotspots of haplotype and genetic variation that will allow the conservation of valuable germplasm, as well as crop wild relatives. Sampling consisted of 170 individuals for three plastid molecular markers comprising the five cultivated species and as outgroups populations of four closely related species were included in the haplotype analyses. Genealogical relationships were determined, along with genetic variation in spatial patterns. The majority of the haplotypes were shared among the nine species in a geographic pattern; however, distant populations of different species also shared haplotypes. Selenicereus monacanthus displayed the highest genetic variation; its haplotype network is complex and intricate, probably related to the management to which the populations have been subjected, in which certain attributes suitable for cultivation and valuable for the fruit market have been selected. Historical evidence suggests that S. undatus has been cultivated in home gardens in the Maya area since pre-Columbian times, and the highest genetic diversity was found there. Conservation of wild crop relatives is important to preserve underutilized crops, therefore southern Mexico and northern Central America are the most relevant regions to protect genetic diversity of pitahayas.","PeriodicalId":12467,"journal":{"name":"Genetic Resources and Crop Evolution","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, screening of wild species resulted in the identification of Psidium cattleianum as one of the sources of resistance. Involving resistant source, interspecific hybrids were developed using ‘Arka Poorna’ and ‘H 12-5’ (Psidium guajava) as the female parents with P. cattleianum var. cattleianum and P. cattleianum var. lucidum as the male parents. In the present study, previously identified 42 resistant interspecific hybrids were characterized based on morphological, molecular and biochemical (phenolic acid and volatile profiling) traits in comparison with their parents at vegetative stage. Among 15 morphological traits, leaf traits viz., leaf blade shape was obovate in eight progenies and leaf base shape was obtuse in 27 progenies resembling male parent. As regards leaf tip, acute shape was found in 35 progenies resembling to P. cattleianum (male parent) and this trait could act as a morphological marker for the identification of hybrid progenies at vegetative stage. The molecular markers (simple sequence repeats, SSR), mpgCIR220 and mpgCIR253 were highly reproducible and could effectively confirmed the hybridity of interspecific hybrid progenies of P. cattleianum var. lucidum and P. cattleianum var. cattleianum, respectively. In addition to morphological and molecular markers, the levels of few volatile compounds viz., β-borbonene, aristolene, (E, Z)-alpha-Farnesene, trans-gamma-bisabolene, neryl acetate, linalyl acetate and furan, 2-ethyl, were similar to those of their male parents.
