However, systematic exploration of the impact of SNP number on inference performance and the application of machine learning algorithms remains lacking. Therefore, we evaluated the impact of SNP number on kinship inference performance and the optimization effects of machine learning methods on the identity-by-state (IBS) algorithm. We constructed multiple SNP panels with SNP numbers ranging from 15,476 to 20,838, and evaluated the performance of the likelihood ratio (LR) method and the IBS algorithm for kinship inference under different SNP numbers based on simulated pedigrees. After selecting the optimal SNP panel, we validated it using real pedigrees and further combined the IBS algorithm with machine learning methods to enhance inference performance. Our results showed that for the LR method, the sensitivity in inferring sixth and seventh degree kinships exhibited a significant positive correlation with SNP number. For the IBS algorithm, although the sensitivity in inferring fourth to seventh degree kinships showed a significant positive correlation with SNP number, the actual improvement was limited (only 0.5%~2.2% increase). Based on these results, we determined the optimal panel containing 20,838 SNPs (21K panel). The 21K panel based on the LR method could accurately infer kinships within sixth degree (with a sensitivity of 93.65% for sixth degree kinship inference), and the 21K panel based on the IBS algorithm could accurately infer kinships within third degree (with a sensitivity of 86.79% for third degree kinship inference). After combining the IBS algorithm with machine learning, the sensitivity for fourth degree kinship inference improved from 69.10% to 87.66%, the sensitivities for fifth and sixth degree kinships improved from 38.03% and 21.41% to 48.75% and 37.80%, respectively.</p>","PeriodicalId":35536,"journal":{"name":"遗传","volume":"48 6","pages":"570-588"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148273287","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}

However, there are still problems such as the imperfect rights' protection system, which hinders the protection and sustainable use of genetic resources and constrains the realization of the fair and equitable benefit-sharing objectives established by the Convention on Biological Diversity. To address these issues, we first define the connotation and legal nature of digital sequence information on genetic resources. Then, we elaborate how digital sequence information on genetic resources aligns with the modern intellectual property systems. For digital sequence information on genetic resources to be protected by intellectual property rights, we analyze the substantive conditions of novelty and practicality as well as the procedural conditions of registration. Building on this analysis, we identify the limitations of existing intellectual property frameworks in accommodating digital sequence information on genetic resources, and propose a normative structure of sui generis right of digital sequence information on genetic resources. The subjects of sui generis right are divided into two levels, i.e. static right attributed to the state, and dynamic right exercised by the farmer collective of specific communities and the uploaders of digital sequence information, exercising respectively in accordance with different functions. The contents of sui generis right include the informed consent right, the source indication right and benefit-sharing right based on licensing. Furthermore, we propose to establish the limitations on sui generis right, such as restriction on scope of application, compulsory licensing and protection periods.

However, without extensive field surveys, achieving timely, large-scale, high-resolution crop identification remains challenging. This study proposes an intelligent crop identification strategy (ICIS) that integrates crop phenological development information with a model transfer strategy based on machine learning, generating 10-meter resolution crop distribution maps of major crop types from 2020 to 2023 in Northeast China (NE). ICIS utilizes time series data from Sentinel-1 (S1) and Sentinel-2 (S2) to extract multi-source temporal features covering the full growth cycles of maize, rice, and soybeans. A Random Forest (RF) classifier was trained on representative sample sites, and model transfer was employed to predict crop distribution across different years and regions. The experimental results show that the models achieved F1-scores above 0.92 across provinces, peaking at 0.97. For rice, the F1-scores for Jilin, Heilongjiang, and Liaoning remained stable at 0.94. Maize F1-scores consistently exceeded 0.92, and although the soybean accuracy varied spatially, it reached 0.97 in certain areas. Comparison with crop area statistics from the China Statistical Yearbook at the city level revealed that the average root mean square error (RMSE) across four years for the three crops was 8.6 × 10<sup>4</sup> ha, with coefficients of determination (R<sup>2</sup>) consistently above 0.90, reaching up to 0.96. These results demonstrated the strong generalizability and robustness of the proposed ICIS Strategy for crop mapping across both temporal and spatial scales. Moreover, this study reveals the complementary strengths and key contributions of optical and Synthetic Aperture Radar (SAR) time series features in modeling crop growth dynamics. Overall, the ICIS provides an efficient and reliable technical means for the rapidly acquiring large-scale crop information.

However, there are no clear recommendations to optimize its production, perhaps due to its strict regulation. In order to optimize the management of the crop, the present work analyzes the effect of irrigation doses and planting density on the growth, production, and quality of the Kompolti variety of hemp, with an irrigation dose equal to the total water requirements of the plant and two deficit treatments, corresponding to 75 and 50 % of these requirements, and two planting densities, 7.0 and 3.1 plants m<sup>−2</sup>. For this, a multi-criteria analysis was performed that proposes the use of the Ordered Weighted Averaging (OWA) operator combined with the CRiteria Importance Through Inter-criteria Correlation (CRITIC) to obtain the weights, where the correlation is obtained as a function of the Pearson-OWA, to determine the aggregation of the quadratic differences by assigning different levels of importance as a function of their size. This application allows for the objective estimation of the weights starting with the attitudinal character of the decisor and its integration to the TOPSIS method. The strength of the innovation proposal has been evaluated, demonstrating that it does not exhibit a rank reversal phenomenon. Furthermore, the resulting ranking has been compared with those obtained using direct assignment methods, such as TOPSIS itself, Multicriteria Optimization and Compromise Solution (VIKOR), and Simple Additive Weighting (SAW), revealing minimal differences. This allows us to regard the proposed method as a generalization of these approaches. In the conditions utilized, the irrigation dose had a greater effect on growth, production, and the content of long fibers, rather than the planting density. In turn, planting density had a greater influence on the cannabidiol (CBD) content as compared to the irrigation dose. The classification obtained was led by the treatments with a higher planting density. Among them, the decrease in the irrigation dose worsened the assessment of the treatments. However, when the planting dose is low, a moderate water deficit improves the results with respect to the complete irrigation treatment or with intense deficit irrigation.</div></div>","PeriodicalId":53443,"journal":{"name":"Information Processing in Agriculture","volume":"13 2","pages":"Pages 253-262"},"PeriodicalIF":7.4,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148060317","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}
