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.</div></div>","PeriodicalId":74667,"journal":{"name":"Reproduction and breeding","volume":"5 3","pages":"Pages 102-109"},"PeriodicalIF":0.0,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144279576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 (H_E = 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.</div></div>","PeriodicalId":74667,"journal":{"name":"Reproduction and breeding","volume":"5 3","pages":"Pages 110-118"},"PeriodicalIF":0.0,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144289158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 &lt; 0.001) according to genetic type. From farrowing to 34 weeks of age, crossbred piglets (F1) had significantly higher weights than local piglets (P &lt; 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 %.

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.</div></div>","PeriodicalId":74667,"journal":{"name":"Reproduction and breeding","volume":"5 2","pages":"Pages 79-87"},"PeriodicalIF":0.0,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a systematic review and meta-analysis of the related literature captured in Google Scholar, MEDLINE, Scopus, PubMed and Web of Sciences databases.

The scope of the study included testicular and epididymal morphology, sperm quality and oxidative stress parameters, steroidogenic enzymes, and sex steroid hormones.
