Ammonia (NH3) volatilization is considered a major pathway of N loss in paddy, yet its response to CRU remains unclear. To evaluate the effects of partially substituting urea with CRU on NH3 volatilization and agronomic performance, field experiments were conducted in rice (Oryza sativa L.)–wheat (Triticum aestivum L.) and rice–rapeseed (Brassica napus L.) rotation with different CRU substitution rates (0%, 10%, 20%, 40%, 80%, and 100%). Results showed that the 40%–100% CRU treatments effectively decreased surface water NH4+-N content and cumulative NH3 volatilization compared to other fertilization treatments. In particular, compared with other treatments, the 40% CRU treatment significantly reduced the ratio of cumulative NH3 volatilization to total N input to 8.4% in the rice–wheat rotation. In the rice–rapeseed rotation, the 40% CRU treatment increased grain yield, partial factor productivity of nitrogen, and apparent N-fertilizer utilization efficiency. In the rice–wheat rotation, the 40% CRU treatment produced the tallest rice plants (52.71 cm), while in the rice–rapeseed rotation, it achieved the highest growth rate (25.97 kg hm−2 day−1). Their results demonstrate that replacing 40% of urea with CRU could effectively reduce NH3 volatilization while simultaneously enhancing rice N accumulation and agronomic performance, particularly in rice–wheat rotation system in the Chengdu Plain.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573574","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}

This study investigated the genetic architecture of shade response in soybean through genome-wide association analysis of 461 diverse accessions evaluated under both normal and shade conditions across two distinct environments in China (Heilongjiang and Inner Mongolia) in the 2022 season. Plant height (PH), main stem node number (MSNN), and pod number per plant (PODn) were assessed to characterize morphological responses to shade stress. Principal component analysis revealed that geographic location was the primary driver of phenotypic variation, explaining 57.4% of total variance. Shade treatment significantly increased PH while reducing MSNN and PODn across both locations, demonstrating classic shade avoidance syndrome traits. Genome-wide association study using 82,208 high-quality single-nucleotide polymorphisms (SNPs) identified 31 significant marker-trait associations (p < 6.0E-4) distributed across 14 chromosomes. Six SNPs were associated with MSNN, 20 with PODn, and five with PH. Notable stable associations included SNP Gm16_9640074 for pod number under normal conditions and Gm08_2576632 for PH under shade stress across both environments. The identification of both environment-specific and stable genetic loci demonstrates the complex genetic architecture underlying shade response in soybean. These findings provide valuable insights into the molecular mechanisms of shade tolerance and identify promising genetic markers for developing soybean varieties better adapted to intercropping systems, potentially enhancing sustainable agricultural practices in diverse agroecological zones.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573668","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}

Rice GI can be reduced by increasing its resistant starch (RS) content, which resists digestion in the gastrointestinal tract. To identify novel genes and gene combinations useful for developing high-RS rice varieties, we identified a novel starch mutant (GSOR 610001), mapped it to the soluble starch synthase IIIa (ssIIIa) locus, and evaluated its impact on RS individually and in combination with two additional genes known to affect RS production: Wx and BEIIb. Of the three genes, the beIIb allele increased RS the most, followed by Wxa. The new ssIIIa mutant increased RS to a lesser degree when genetically combined with the high-amylose Wxa allele and the non-mutant BEIIb allele; instead, ssIIIa+beIIb double mutants decreased RS indicating the two mutant genes act antagonistically. The higher RS of beIIb was associated with its amylopectin having higher proportion of long and degree of polymerization (DP) 19–37 chains and less branching than the wild type. The ssIIIa mutant had lower long amylopectin chains than the wild type but maintained its amylopectin branched structure, which prevented short-term RS formation after cooking. Increased RS from ssIIIa was associated with amylose content. The antagonistic effect of adding ssIIIa to beIIb was due to the reduction of less-branched, long amylopectin chains of beIIb. In summary, the target genotype that optimized RS was Wxa+beIIb+SSIIIa (averaged 6.5 ± 0.8% RS [milled basis]), and the validated molecular markers will speed development of rice varieties having high RS/low GI using marker-assisted selection.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 4","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144514756","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}

We employed three genome-wide association study (GWAS) models (fixed and random model circulating probability unification [FarmCPU], Bayesian information and linkage-disequilibrium iteratively nested keyway [BLINK], and multiple locus mixed model [MLMM]) to dissect the genetic basis of the oleic acid, linoleic acid, and oil content.

Notably, four SNPs (Chr1_1693157, Chr3_23284702, Chr5_17024932, and Chr9_1711873) were common across all three models, suggesting stable and robust associations between oleic acid and oil content. Candidate gene analysis revealed four notable sequences linked to these loci: a transcription repressor OFP8 (Sesamum alatum), an HVA22-like protein, a 3-oxoacyl-[acyl-carrier-protein] synthase 3 A, and a putative phospholipid diacylglycerol acyltransferase 2 in (S. indicum), all of which may play key roles in oil biosynthesis and accumulation. Environment-specific loci have also emerged for linoleic acid, particularly on chromosomes 6, 9, and 13.

This resistance has been incorporated into several cultivars and is the only currently available genetic resistance in commercial cultivars; however, growers still favor susceptible cultivars for their superior yield stability and potential. A new source of resistance from the wild species Arachis stenosperma has been introduced to cultivated peanut by backcrossing, conferring near-total immunity to RKN reproduction and galling under controlled conditions. In field trials with and without nematode pressure, we tested the RKN resistance and agronomic performance of a selection of these lines. We found reductions in RKN galling and egg production, averaging 98.6% and 99.1%, respectively, consistent with previous studies. Backcrossed lines with or without the RKN resistance locus were similar or superior to popular peanut cultivars in seedling vigor and stand visual ratings. Under heavy nematode pressure, the resistant backcrossed lines yielded an average of 75% more than popular susceptible cultivars. Without nematode pressure, the yield of the backcrossed lines was statistically indistinguishable from the cultivars. Analysis of agronomically important traits including pod constriction and 100-seed weight showed no significant difference between nematode-resistant lines and the popular cultivar checks.

The discovery and development of hybrid grain sorghum in the 1950s privatized much of the sorghum breeding industry, but the public sector continues to make contributions to sorghum improvement. There is a need to assess the relative merits of different sorghum programs and their complementation. Within this context, this study evaluated the productivity of grain sorghum hybrids made across and within three public and one private sector breeding program. The parents consisted of 12 elite pollinators and 12 elite seed parents from each program crossed in a partial factorial to create over 1200 hybrids that were grown in 25 sparse trials from South Texas through northern Kansas in 2022 and 2023. The highest yielding hybrids were consistently produced using inbreds from different programs, which indicates that inbred exchange can increase hybrid productivity. In addition, the value of specific adaptation to a target region was made apparent by the increase in performance of programs in their primary selection environments. The study herein demonstrated that hybrids made between private and public breeding programs improved performance, highlighted the value of germplasm exchange between private and public sector programs, and encouraged private sector companies to explore the value of incorporating public material into their program.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/csc2.70101","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144292844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings presented here suggest that the successful passing of the torch in such programs depends not only on strategic institutional support but also, critically, on the routine actions and mindset of the breeders entrusted with their leadership.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 3","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/csc2.70094","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144256094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
