Peanut (Arachis hypogaea L.) is a globally significant oilseed crop, with China being the largest producer and consumer. High-oil peanut varieties, characterized by oil content exceeding 55 %, offer substantial economic and nutritional benefits. This study comprehensively analyzed 238 high-oil peanut varieties in China, focusing on their agronomic traits, quality characteristics, yield potential, and disease resistance. Correlation analysis highlights a trade-off between oil and protein content, posing a challenge for breeding high-protein, high-oil varieties. Disease resistance analysis indicates that while a considerable proportion of varieties exhibit resistance to major diseases like leaf spot, bacterial wilt, and rust, the level of high resistance remains low, necessitating further breeding efforts. Pedigree analysis underscores the importance of key parents like Kaixuan 016 and CTWE in high-oil peanut breeding. The findings suggest integrating molecular breeding techniques, exploring wild relatives for genetic diversity, and developing multi-trait breeding objectives to enhance oil content, disease resistance, and environmental adaptability. This research provides a solid foundation for future breeding programs aimed at improving the yield, quality, and resilience of high-oil peanut varieties to meet the growing global demand for edible oils.

Indigenous Ethiopian sheep inhabit diverse environmental conditions and hold distinct morphological traits, including variations in tail phenotypes. Characterizing their genetic diversity is crucial for developing appropriate breeding and conservation schemes. The current study aimed to determine the genetic diversity and population structure of two underrepresented indigenous sheep populations in Ethiopia: Selale and Semien. A total of 48 whole blood samples were collected randomly from the 24 Selale and 24 Semien sheep. Publicly available single nucleotide polymorphism genotype data from five Ethiopian sheep populations (Arsi-Bale, Menz, Blackhead Somali, Horro, and Adilo) were included in the analysis. Additionally, for an even broader perspective, four breeds from Asia and other parts of Africa (Afshari, Egyptian Barki, Red Maasai, and Indian Garole) were used to evaluate the genetic connections of the study populations. The average genetic diversity (expected heterozygosity) ranged from 0.325 for Ari-Bale to 0.362 for the Selale sheep, with a mean of (HE = 0.344) across all populations. Estimates of genetic differentiation among sheep populations in Ethiopia ranged from 0.019 between Selale and Horro sheep to 0.077 between Semien and Arsi-Bale sheep. The analysis of molecular variance indicated that 94.25 % and 3.56 % of the genetic differentiation were attributable to variances within and among populations, respectively. Principal component and admixture analyses revealed three distinct genomic backgrounds of indigenous sheep populations in Ethiopia, consistent with their tail morphology and ecological distribution: long fat-tailed, short fat-tailed, and fat-rumped sheep. These findings can help formulate strategies for sustainable genetic improvement, conservation, and utilization of indigenous sheep populations.
土着埃塞俄比亚羊生活在不同的环境条件下，具有不同的形态特征，包括尾巴表型的变化。确定其遗传多样性特征对于制定适当的育种和保护计划至关重要。目前的研究旨在确定埃塞俄比亚两个代表性不足的土著绵羊种群：Selale和Semien的遗传多样性和种群结构。随机抽取24只Selale羊和24只Semien羊48份全血样本。来自5个埃塞俄比亚绵羊群体（Arsi-Bale、Menz、Blackhead somalia、Horro和Adilo）的公开单核苷酸多态性基因型数据被纳入分析。此外，从更广泛的角度来看，来自亚洲和非洲其他地区的四个品种（Afshari，埃及Barki， Red Maasai和印度Garole）被用来评估研究群体的遗传联系。阿里-贝尔羊的平均遗传多样性（期望杂合度）为0.325 ~ 0.362，所有群体的平均遗传多样性（HE = 0.344）。埃塞俄比亚绵羊群体间遗传分化的估计值从Selale羊和Horro羊的0.019到Semien羊和Arsi-Bale羊的0.077不等。分子变异分析表明，94.25%和3.56%的遗传分化可归因于群体内变异和群体间变异。主成分分析和混合分析揭示了埃塞俄比亚本地绵羊种群的三种不同的基因组背景，与它们的尾巴形态和生态分布相一致：长肥尾羊、短肥尾羊和肥臀羊。这些发现有助于制定可持续遗传改良、保护和利用本地绵羊种群的策略。

Local pigs in Benin are highly valued by the population, yet their suboptimal performance limits their breeding potential. The objective of this study was to enhance the zootechnical performance of local pigs in Benin by crossing them with the stress-negative Pietrain. A total of three batches were created. The first group consisted of 12 local females, mated by a local boar (LO), the second of 12 Pietrain females, inseminated with Pietrain semen (Pi), and the third of 12 local females inseminated with Pietrain semen (LO x Pi). The growth performance of piglets from each batch was collected from birth to 34 weeks of age. The data were subjected to a two-criteria analysis of variance, including the effects of piglet genetic type and sex. The results indicated that piglet weight, performance, and average daily gain (ADG) varied significantly (p < 0.001) according to genetic type. From farrowing to 34 weeks of age, crossbred piglets (F1) had significantly higher weights than local piglets (P < 0.05). The same was true of ADG. The Pietrain exhibited significantly higher growth performance than the other two genetic types. The observed performances did not vary according to sex within the same genetic type. In general, females were heavier than males between 28 and 34 weeks of age, regardless of genotype. The heterosis effect of the cross was positive, with a range of 3.71–11.14 %. The findings of this study indicate that the Pietrain genotype improves the growth performance of local pigs in Benin.
贝宁的本地猪受到人们的高度重视，但它们的次优性能限制了它们的育种潜力。本研究的目的是通过与应激阴性Pietrain杂交来提高贝宁当地猪的动物技术性能。总共创建了三个批次。第一组由12头当地母猪组成，由一头当地公猪（LO）交配；第二组由12头Pietrain母猪组成，用Pietrain精液（Pi）受精；第三组由12头当地母猪组成，用Pietrain精液（LO x Pi）受精。从仔猪出生至34周龄收集每批仔猪的生长性能。对数据进行双标准方差分析，包括仔猪遗传类型和性别的影响。结果表明，仔猪体重、生产性能和平均日增重（ADG）差异显著(p <；0.001)。从分娩期到34周龄，杂交仔猪（F1）的体重显著高于本地仔猪(P <；0.05)。ADG也是如此。皮特兰的生长性能显著高于其他两种遗传类型。在同一遗传类型内，观察到的表现不因性别而异。一般来说，无论基因型如何，雌性在28至34周龄之间都比雄性重。杂种优势效应为正，在3.71 ~ 11.14%之间。本研究结果表明，Pietrain基因型提高了贝宁当地猪的生长性能。

The last two centuries have seen the occurrence of several theoretical and scientific advancements that revolutionized plant science. From Mendel's intuitions to discovery of DNA toward up to the development of next generation sequencing technologies, it is nowadays possible to precisely investigate the genetic basis of traits of agricultural interest accelerating crop improvement. The availability of catalogues of thousands of genomic markers in many species, provides new opportunities to identify favourable allelic variants supporting genomic assisted breeding programs. In addition, the release of complete plant genomes sequences and the development of pangenomes make possible the identification of structural variants facilitating mining of favourable alleles. Beyond technological advancements, data integration is crucial for the comprehensive understanding of the biological processes underlying plant traits and their interactions with the environment. This perspective article illustrates how omics technologies can be used to tailor genomic tools for different breeders' needs to revolutionize crop improvement.

Sorghum is a climate-resilient food security and nutrition crop, which has been produced as a staple food in the semi-arid tropical regions of the world. However, moisture stress is increasingly affecting sorghum performance, especially at the flowering stage when water availability is critical for grain filling, thus reducing the sorghum grain yield. Therefore, the experiment was conducted to identify the best-adapted superior sorghum genotypes and quantify genetic variability, heritability and genetic advance as percent of mean for yield and yield components of sorghum genotypes. An alpha lattice experimental design with two replications was used to assess 42 sorghum genotypes in total at Mieso and Kobo. The combined analyses of variance revealed the presence of substantial genetic variation among sorghum genotypes for yield and agronomic traits. Among the traits with high genotypic coefficients of variation and heritability observed for plant height, panicle width and panicle yield were linked with higher values of genetic advance as a percentage of the mean. This result indicates that additive gene action governs the variability of these traits. High heritability and genetic advancement percentages were obtained for plant height (95.63 and 45.39 %, respectively), 1000-seed weight (77.98 and 23.86 %, respectively), panicle exertion (74.87 and 51.88 %, respectively), and panicle yield (65.43 and 37.32 %, respectively). The maximum grain yield was obtained from genotype 4x14 (6.32 tha-1), followed by genotypes 8x15 (5.92 tha-1), 1x15 (5.88 tha-1), 13x14 (5.78 tha-1) and 6x15 (5.57 tha-1), with an average value of 5.00 tha-1, which was greater than the mean value of the check (ESH-4) (4.77 tha-1). In general, this study revealed wider genetic variability in the tested genotypes for different traits under moisture stress conditions. The selection and hybridization on these genotypes for a desired traits with high (H2) coupled with higher GCV and GAM will be effective to develop and select high yielding, stable and early sorghum genotypes. The results of this investigation would help determine the most pertinent genetic material and plan the subsequent breeding program to encourage efforts for varietal improvement. The most promising and potential genotypes that could be used commercially were identified by the study following an in-depth investigation of their superiority and yield stability over time across different parts of the country.

Di-n-butyl phthalate (DBP) is a ubiquitous environmental contaminant widely used in personal care products and medical products, causing male reproductive toxicity in humans and animals following exposure. It has endocrine-disruptive activities, causing adverse effects on the male reproductive system. This study aimed to investigate the male reproductive injury induced by DBP in animals. We conducted a systematic review and meta-analysis of the related literature captured in Google Scholar, MEDLINE, Scopus, PubMed and Web of Sciences databases. This review included animal studies that were postnatally exposed to DBP. After applying the inclusion and exclusion criteria, a total of 48 relevant studies were selected, which included studies in rats (n = 29), mice (n = 5), rabbits (n = 3), birds (n = 6), and fish (n = 5) exposed to DBP. The scope of the study included testicular and epididymal morphology, sperm quality and oxidative stress parameters, steroidogenic enzymes, and sex steroid hormones. The meta-analysis focused on rat studies, which revealed a significant decrease in sperm count (p < 0.001), sperm motility (p < 0.001), superoxide dismutase (SOD, p < 0.001) activity and testosterone (p < 0.001) concentration. Moreover, DBP exposure significantly increased sperm abnormality (p < 0.001), catalase (CAT; p = 0.003) activity and malondialdehyde (MDA; p < 0.001) levels. Postnatal exposure to 1 mg/kg DBP could decrease the sperm count, sperm motility, testosterone concentration, and SOD activity by 5.87 %, 0.17, 7.46 % and 21.38 %, respectively. As a result of the meta-analysis, SOD activity was more sensitive to DBP following postnatal exposure than CAT activity or MDA levels, while sperm abnormality was less susceptible than sperm count and sperm motility to DBP exposure. Generally, the systematic review and meta-analysis demonstrated that postnatal exposure to DBP-induced male reproductive injury by inducing oxidative stress and altering steroidogenesis, and sex hormones in animals. Moreover, the review identified important gaps in animal studies of dermal exposure to DBP, emphasizing the need for further research to assist in conducting more rigorous epidemiological and risk assessment studies that represent real-life exposure scenarios.

Moreover, DBP exposure significantly increased sperm abnormality (<em>p < 0.001</em>), catalase (CAT; <em>p = 0.003</em>) activity and malondialdehyde (MDA; <em>p < 0.001</em>) levels. Postnatal exposure to 1 mg/kg DBP could decrease the sperm count, sperm motility, testosterone concentration, and SOD activity by 5.87 %, 0.17, 7.46 % and 21.38 %, respectively. As a result of the meta-analysis, SOD activity was more sensitive to DBP following postnatal exposure than CAT activity or MDA levels, while sperm abnormality was less susceptible than sperm count and sperm motility to DBP exposure. Generally, the systematic review and meta-analysis demonstrated that postnatal exposure to DBP-induced male reproductive injury by inducing oxidative stress and altering steroidogenesis, and sex hormones in animals. Moreover, the review identified important gaps in animal studies of dermal exposure to DBP, emphasizing the need for further research to assist in conducting more rigorous epidemiological and risk assessment studies that represent real-life exposure scenarios.</div></div>","PeriodicalId":74667,"journal":{"name":"Reproduction and breeding","volume":"5 2","pages":"Pages 54-68"},"PeriodicalIF":0.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large yellow croaker is one of the species with the highest production of marine fish culture in China. Germplasm resources are the indispensable material basis for the healthy and sustainable development of large yellow croaker aquaculture industry. It is of great significance to systematically carry out the collection and preservation, identification and evaluation, and germplasm innovation of large yellow croaker germplasm resources. This paper summarizes the progress in the conservation and exploitation of large yellow croaker germplasm resources and germplasm innovation. Around the main line of conservation of large yellow croaker germplasm resources and the creation of good varieties, the development direction of creating major new varieties for complex economic traits (e.g., disease resistance, stress resistance, quality, and feed utilization efficiency, etc.) was proposed, which provided theoretical support for realizing the significant improvement of the coverage rate of improved varieties of large yellow croaker and the healthy development of large yellow croaker industry.
