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":"76 1","pages":""},"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":"34 1","pages":""},"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. These novel volatiles, morphological traits and molecular markers can be used to enhance the speed of breeding by reducing time for progeny identification.","PeriodicalId":12467,"journal":{"name":"Genetic Resources and Crop Evolution","volume":"30 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141778486","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 study explored genetic variability and phylogeographic structure of 28 populations using three chloroplast intergenic spacer regions sequences. Bermudagrass populations at different latitudes exhibited a high level of genetic differentiation from populations at different longitudes. Populations at different latitudes indicated higher gene flow than populations at different longitudes, which attributed to higher genetic variation within population along the latitudinal gradient than longitudinal gradient. Contrast to apparent phylogeographic structure in populations along the latitudinal gradient, majority haplotypes sharing occurred in populations along the longitudinal gradient. Populations at high-latitudes showed distinct genetic diversity and haplotypes from populations at mid-latitudes. The Dabieshan and Nanling Mountains acted as the geographic barriers along the latitudinal gradient, leading to the intraspecific phylogeographic subdivision and divergence.

It generated an average income of US$D 80 during the vegetable harvesting season, per individual seller. This species has numerous applications for not only rural dwellers, but also for those in urban areas where it is used for food, healthcare and arts. However, the plant is overexploited by users of this multipurpose species. Among the threatening factors are bushfires and the low natural regeneration due to poor seed germination caused by seed dormancy. This overexploitation will induce the depletion and disappearance of the species in its natural habitat, thus causing an ecological imbalance and genetic erosion. The conservation of this species must therefore be done through its preservation in the natural environment, production, domestication and awareness of the populations. In this work, we review the existing literature on the species, focusing on geographic distribution, utilisation and threats to natural populations, propagation and agronomy, national and international trade, conservation of genetic resources, prospects for domestication and commercial production, and methods for genetic improvement. The findings provide an overview to guide the development of strategies for genetic resource conservation, domestication, commercial production, and genetic improvement to meet the increasing demand for this resource.","PeriodicalId":12467,"journal":{"name":"Genetic Resources and Crop Evolution","volume":"4 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141778491","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}
