Across four growing seasons with 12 rainfall situations, incorporating annual forages into fallow period significantly increased productivity and resource use efficiency, and the system productivity and net income were influenced by the intra- and interannual variability rainfall. Increasing precipitation significantly enhanced productivity. Compared to CK, the R+30% scenario wheat equivalent yields in F–W, oat–winter wheat (O–W), soybean–winter wheat (S–W), and vetch–winter wheat (V–W) systems were increased by 17.9%, 20.3%, 18.7%, and 25.5%, respectively.

Creating biodiverse pastures with perennial native warm-season grasses (NWSGs) could alleviate fescue toxicity by providing alternative sources of forage. Legumes added to NWSG mixtures could also provide floral resources for insect pollinators, reseeding, and benefit cattle performance. A 3-year grazing study conducted in Virginia tested the feasibility of this biodiverse grazing system to improve animal performance and floral resources for pollinators. The experiment consisted of three treatments applied to 1-ha pastures: (1) biodiverse—70% planted to tall fescue with 30% planted to a NWSG and legume mixture, (2) shade—100% tall fescue pasture supplemented with artificial shade, and (3) control—100% tall fescue pasture with no shade. Pastures were continuously stocked with cattle each summer from 2021 to 2023. Average daily gain of cattle in the biodiverse treatment ranged from 31% to 85% greater than other treatments likely because animals had access to NWSG and white clover (<i>Trifolium repens</i> L.) forage. Midday body temperatures of cattle in the biodiverse treatment were also 0.3°C–0.5°C lower than those on the control treatment. Flower production was limited to white clover.

Barley yellow dwarf virus (BYDV) is one of the most serious worldwide virus threats to cereal crops. Soil-borne wheat mosaic virus (SBWMV) has been present in the Great Plains and responsible for wheat damage for over a century. Identification of additional sources of genetic resistance is paramount to combat the potential damage from these viruses. We constructed a panel of 269 winter wheat cultivars and breeding lines to assess the resistance to naturally occurring BYDV and SBWMV in a Kansas nursery. These lines were sequenced using exome and promoter capture identifying over 640,000 variants for association analysis with visual disease severity ratings. We found 10 and seven significant regions affecting resistance to BYDV and SBWMV, respectively. These regions include the <i>Bdv2</i> and <i>Sbwm1</i> loci, as well as novel loci affecting virus resistance. Most of the novel associations are rare, with effect sizes ranging from 5% to 22%. We performed a survey of the viral population present in the disease nursery, which confirmed the presence of both BYDV and SBWMV and revealed differences in virus population from year to year. Additionally, it suggested that co-infections of multiple viruses are common, demonstrating the need for breeding lines harboring resistance to multiple viruses. Deployment of these novel genetic resistance regions in combination with existing resistance loci should allow for increased resistance and potentially more sustainable viral control and reduce the risks associated with wheat yield loss due to these viruses.</p>","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/csc2.70016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143564988","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}

Two growth chamber experiments were conducted in diverse canola genotypes (10 each of winter and spring types) at six salinity levels (0, 2, 4, 6, 8, and 10 dS m⁻¹ EC). Increasing salinity levels reduced the emergence indices (emergence percentage, emergence rate index, corrected emergence rate index, and emergence velocity) and salt tolerance index (STI). An approximate threshold salinity range of 6–8 dS m⁻¹ ECs was determined. Importantly, salinity at ≥8 dS m⁻¹ EC levels substantially reduced seedling emergence indices and delayed emergence by 3–7 days after seeding. Winter genotypes CP1022WC/Chinook and CP320WRR, and spring genotypes Monarch, PI597352, PI601200, and PI432395 had higher STI and emergence indices.
