Here, we aimed to utilized yield-related genetic loci to breed high-yielding maize varieties. We developed a recombinant inbred line (RIL) population comprising 320 lines and investigated seven ear-related and two kernel-related phenotypes in two environments. Using a linkage map (length, 2193.38 ​cM) with 2154 genetic bins, we identified 79 unique quantitative trait loci (QTLs), 37 (46.83 ​%) of which had been reported previously. Additionally, nine major QTLs and 13 pleiotropic QTLs were detected, with additive effects showed in traits of ear row number and ear length. We further analyzed lines containing one to six major QTLs associated with ear-related traits. The phenotypic values of all seven ear traits were significantly positively correlated with the number of favorable haplotypes of major QTLs (FHMQs). Materials containing multiple FHMQs exhibited higher yield, which was indicative of a high breeding value. We crossed the RIL materials with three tester lines, and the yield of the hybrids with parents containing three to four FHMQs were significantly higher than those of the hybrids with parents containing two or fewer FHMQs. This result confirmed a positive correlation between hybrid yield and the number of FHMQs in the parents. Finally, we successfully generated three new hybrid varieties by crossing three lines pyramiding three, four, and four FHMQs with the tester line Jing724. The materials generated in this study exhibit excellent breeding potential for enhancing maize yield.</div></div>","PeriodicalId":100065,"journal":{"name":"Agriculture Communications","volume":"3 2","pages":"Article 100083"},"PeriodicalIF":0.0,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143870165","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 microcapsules showed an intact particle morphology and successful encapsulation of oat oil by the wall materials. Microcapsules with small granular starch as the wall material formed spherical aggregates after spray drying. OSA modification mainly occurred in the amorphous region of the starch and thus did not change the starch crystal pattern, but it led to a decrease in the relative crystallinity (RC) of the starch. OSA modification enhanced the emulsifying capacity of starch, whereas it decreased their thermal stability (<em>p</em> ​&lt; ​0.05). Q-OSA, with A-type starch and the smallest particle size (1.48 ​μm), showed the highest degree of substitution (DS, 0.0181), the best emulsification properties (EAI, 1.336 ​m²/g), and the greatest encapsulation efficiency (EE, 90.77%). Conversely, P-OSA, with C-type starch and the second largest particle size (26.63 ​μm), smaller than Pt-OSA (B-type, 41.15 ​μm), exhibited the lowest DS (0.0091) and EE (79.66%). OSA modification reduced the oil release of microcapsules in the gastric stage, thereby achieving the targeted release of oat oil at the intestinal stage. In particular, Q-OSA was the most effective in protecting oat oil against pepsin and the strong acidic environment.

This study assessed whether photoperiod affected the gonad development of Pacific abalone (<em>Haliotis discus hannai</em>), a commercially valuable marine mollusk.

There were no significant differences in the survival rates of the three groups. However, compared to the other two groups, the 18L:6D photoperiod indicated a significantly higher gonad index (<em>p</em> ​&lt; ​0.05). The concentrations of 17β-estradiol (E2) and testosterone (T) were also significantly higher in the LL group (<em>p</em> ​&lt; ​0.05).

However, it is generally associated with high resource consumption, including building materials, consumables, and energy, raising severe concerns about its future sustainability, especially the intensity of its carbon emissions, which is less well-understood. This study focused on the carbon emissions of two typical protected cultivation constructions for tomato cultivation in China, using life cycle assessment (LCA). Tomato production generated 354.4 and 173.1 kg CO₂-eq/ton carbon emissions in a typical solar greenhouse in northern China and a typical naturally ventilated polyhouse in southern China, which represented 41.9% and 21.7% reduction, respectively, compared to field production in the same area. Further analysis of protected cultivation inputs revealed that agricultural consumables are the main contributors to carbon emissions. Among them, fertilizers were the dominant contributor to carbon emissions, accounting for 73.0% and 67.5% of the total carbon emissions for solar greenhouses and polyhouses, respectively. Based on this finding, a sensitivity analysis revealed the potential of two advanced fertilizer management practices to reduce carbon emissions. Drip irrigation and slow-release fertilizers in protected cultivation can reduce carbon emissions by 16.5–17.7% and 12.9–13.8%, respectively, compared to traditional chemical fertilizers. In addition, the analysis of environmental effects suggested that protected tomato production can significantly reduce environmental impact.
