It is an F₄-derived selection from the cross R12-2237 (drought-tolerant) × R12-519 (high-yielding). R19-42848 is a conventional (non-genetically modified) soybean with a relative maturity of 5.2. Plants have determinate growth habit with purple flower color, gray pubescence, and tan pod wall at maturity. Seed of R19-42848 has buff hilum color, 100-seed weight of 13.8 g, and contains on average 404.5 and 211.5 g kg⁻¹ of protein and oil on a dry basis, respectively. R19-42848 showed high-yielding and broad adaptability across 28 environments in Arkansas and three other states during the 4 years of yield trials under irrigated conditions (4275 kg ha⁻¹, 91.4% of the checks’ mean). Additionally, it demonstrated high yield and slow canopy wilting in rainfed conditions across 14 environments over 3 years (2489 kg ha⁻¹, 96.2% of the checks’ mean). Under irrigated conditions, R19-42848 yielded numerically higher than drought-tolerant check Ellis (105.2%), while statistically similar in rainfed conditions (99.9%).

This study aims to describe and present the Multiple Synthetic Derivative (MSD) population for registration as a germplasm resource to mine desirable climate-smart traits or genes from <i>Ae. tauschii</i> more systematically and efficiently. The MSD population was developed by crossing and backcrossing the Japanese wheat cultivar, ‘Norin 61’ (N61) to 43 different primary synthetics (PS) derived from a diverse set of 43 <i>Ae. tauschii</i> accessions. Evaluation of the MSD population under various abiotic stresses including heat, drought, low nitrogen (N) and phosphorus (P), demonstrated wide phenotypic diversity for all traits including grain yield, biomass, days to heading, and stress tolerance index (STI). Across all environments, the maximum grain yield and biomass recorded by some MSD lines were always higher than that of the recurrent parent (N61) and both heat-stress adapted varieties, Goumria and Imam. The MSD population showed a wide range in days to heading. The maximum STIs for heat, drought, low N and P of some MSD lines were higher than that of N61, Goumria, and Imam. Our results indicated the usefulness and effectiveness of MSD population as a platform for mining and exploiting heat, drought, and nutrient-use efficient traits in a common hexaploid wheat background.

Wet meadows require plant materials with excellent seedling vigor and tolerance to consistently wet conditions. Creeping foxtail grows well under these wet conditions but lacks the seedling vigor to consistently establish under the competition from other plant materials. We developed USDA-Accelerate as a Syn₁ cultivar derived from two cycles of selection from 63 genotypes from four germplasm accessions and the cultivar ‘Garrison’. The first cycle of selection was for visual disease resistance, seed production, and seed shatter, and the second cycle of selection was for deep seeding depth emergence. We compared the total emergence and emergence rate of USDA-Accelerate to that of Garrison under two rounds of deep seeding depth evaluations in the greenhouse and the agronomic performance under three field environments. USDA-Accelerate had 140% greater total emergence, 142% greater emergence rate, and similar stand establishment, herbage dry mass, and nutritive value when compared to Garrison. This release supports the USDA-ARS effort to supply improved perennial grass cultivars for animal feed and soil stabilization for the western United States.

Tepehuán-RS showed high grain yield in low plant densities. It was jointly developed by INIFAP, Postgraduate College and Autonomous University of Chihuahua, released by INIFAP-Sierra of Chihuahua Experimental Station. Bean is one of the most important crops in Mexico by sown area, with 1.4 million ha. The mean bean yield in Mexico is 520 kg·ha⁻¹ in rainfed conditions. Production is considerably affected by two main problems, drought and low densities of sown and harvested plants. This sparse plant cover exposes the soil for a longer period, leading to increased water loss through evaporation and exacerbating drought stress.
