Abstract	Many developing countries are falling behind sustainable development goals: food and nutrition levels have deteriorated due to conflict, climate change, and the Covid pandemic, while global ambitions for achieving sustainable food security and adequate nutrition have increased. But what are the prospects of achieving sustainable, healthy food for all? What is the best response to concerns about growing differentiation among developing countries in terms of domestic agricultural and industrial performance? 'Food for All' explores how developments since these organizations were established have led to changes in the provision of international financial and technical assistance in support of the global food and agriculture system and how developing countries' own efforts have helped transform them.

Abstract	Selenium (Se)‐affected stormwater runoff raises concerns about potential downstream impact of Se on aquatic ecosystems. Unplanted (UNP) detention ponds augmented with cattail (Typha angustifolia L.; CAT) and duckweed (Lemna minor L.; DWD) may provide a solution for continuous, rapid abatement of Se‐affected runoff. This research was conducted to evaluate the efficacy of CAT or DWD and determining the distribution of Se within a continually flooded detain and drain system. Microcosms containing 3 kg of soil planted to either one CAT, 25 g fresh DWD, or left unplanted (UNP, control) were flooded with a 3‐L solution at 40 μg Se L⁻¹, as sodium selenate (Na₂SeO₄), or a zero Se control. Over two 10‐d flood–discharge cycles (FDCs), plants in microcosms were evaluated in growth chambers maintained at 30 °C under a 12‐h photoperiod with 400 μmol m⁻² s⁻¹ irradiance. Initial and final water, soil, plant, and granular activated charcoal (GAC) were analyzed for total [Se] with inductively coupled plasma–mass spectroscopy (ICP–MS). Data were analyzed with PROC GLM (SAS EG 7.1) at α = .05. Within 10 d after Se application, CAT and DWD decreased aqueous Se from 40 μg Se L⁻¹ to below the 11.8 μg Se L⁻¹ threshold. Selenium recovery ranged between 75 and 100% of the applied Se. In continually flooded systems, the primary elimination pathway appears to be associated with the soil solid phase. Cattail and DWD are suitable species for constructed wetland phytoremediation of Se‐affected runoff. The microcosm design presented may be useful for future evaluations.

Abstract	Salinity is one of the most important challenges facing future global barley (Hordeum vulgare L.) productivity, as it causes major reduction in germination, growth, grain yield, and quality. Screening germplasm for salinity tolerance at germination is vital to breeding programs because germination is the first stage of plant growth and occurs near the soil surface where salt can accumulate in high concentrations. This experiment was conducted to assess salinity tolerance of 249 genotypes (64 diploid (2×) H. vulgare crosses; 174 tetraploid (4×) H. vulgare crosses; and 11 parents) at the seed germination stage. Salinity treatments applied at imbibition included concentrations of 0, 100, 200, and 300 mM salinity and were maintained for 10 d. Analysis of variance of all families indicated significant (P ≤ .001) genotype × salinity interaction for final germination percentage (FG%), corrected germination percentage (CG%), and germination index (GI) at all treatment levels, indicating high genetic variation for salinity tolerance among screened genotypes. The mean of all measured parameters (FG%, CG%, and GI) decreased as salinity concentration increased. These responses can be used to identify genotypes with salinity tolerance at germination. At 300 mM salinity, progenies in 2× Families 1 and 2 were 14.3 and 12.5% saline tolerant, respectively. A total of 29 progenies from 4× families were tolerant to 300 mM treatment at germination. These progenies would have an economic value for improving barley tolerance for salinity.

Abstract	Salinity is one of the most detrimental abiotic stresses affecting crop productivity worldwide. To identify barley (Hordeum vulgare L.) genotypes with satisfactory production under increased salinity, screening must focus on multiple phenological stages, specifically the earliest stages (germination and seedling), when plants are most vulnerable to stress. This experiment was conducted in a greenhouse to assess salinity tolerance of 161 genotypes (34 genotypes of 2× H. vulgare crosses; 116 genotypes of 4× H. vulgare crosses, and 11 parents). Beginning at the third leaf stage, seedlings were irrigated with solutions of 0, 100, 200, and 300 mM NaCl for 21 d. Analysis of variance showed significant effects due to genotype, salinity level, and their interaction for shoot dry weight (SDW). Overall, SDW showed negative association with plant height, whereas it was positively associated with tiller number, fertility, 100‐seed weight, and grain yield. Mean SDW of all families decreased as salinity treatment level increased. Families varied in SDW and salinity susceptibility index (SSI) at 300 mM salinity treatment. Diploid Families 2 and 3 had the greatest SDW and lowest SSI (<1). Thirty percent of crosses from tetraploid Family 2 yielded the greatest SDW, whereas the same proportion of crosses from tetraploid Family 4 showed the greatest salinity tolerance as measured by SSI. These crosses, as well as the female parents, are valuable germplasm for improving salinity tolerance in barley breeding programs.

Abstract	Salinity is a critical challenge facing productivity of barley around the world, necessitating the development of salinity tolerant varieties. Screening genotypes of two barley species during germination and seedling growth stages was conducted to identify genotypes with superior performance under saline stress conditions. Five genotypes of domestic barley (Hordeum vulgare L.) and six of wild barley (H. bulbosum) were used in this study. Genotypes were germinated in solutions of 0, 1.0, 1.5, and 2.0% NaCl (0, 171, 257, and 342 mM NaCl). Shoot and root length were recorded 10 d after germination. Upon reaching the three‐leaf stage, seedlings were irrigated with 500 mM NaCl solution for 3 wk to evaluate salt tolerance using the growth index. The analysis of variance showed there was a high genetic variation among genotypes. Only genotypes PI220054, PI227242, and PI420909 of wild barley species germinated at the 2% NaCl salinity level. All domestic barley genotypes failed to germinate at 2% NaCl salinity and showed reduction of root and shoot length greater than wild barley genotypes under saline conditions. Mean root and shoot lengths decreased as the level of NaCl increased for all genotypes. This condition was more intense in domestic than wild barley genotypes. Seedling screening showed PI268243 had the greatest growth index compared with the other genotypes. The PI227242 genotype had the greatest growth index among wild barley genotypes. Regression analysis indicated that there was no relationship between salt tolerance at germination and seedling growth stages.

Abstract	Orchardgrass (Dactylis glomerata L.) could serve as a cool‐season perennial in southeastern production systems, but often does not behave as a true perennial under high temperature stress conditions of the region. This work sought to develop heat‐tolerant orchardgrass germplasm through recurrent phenotypic selection (RPS) that would both reduce secondary seed dormancy caused by high soil temperatures and improve stand persistence over summer months. Selection was conducted in a growth chamber 40/30 °C (12/12 h, light/darkness), with germinated seedlings subjected to an additional 2–3 wk of 40/30 °C conditions. The base germplasm (Cycle 0) and selected individuals (Cycles 1–3) were transplanted into the field, then harvested for seed. Forty‐degree germination tests compared mean cumulative germination, velocity of germination within 8 d (VOG₈), and realized heritability (hRealized2). Stand persistence was assessed 1 yr after transplanting. Results from 2018 tests indicated Cycle 3 seed germination was greater (82%) than all previous cycles of selection, and VOG₈ was eight times greater than that of Cycle 0. Additive gene action also increased, with final hRealized2 = .45, and preliminary data from Cycle 3 10‐mo‐stand persistence (56%) was double that of Cycle 0 (27%). These results indicated a significant improvement over the base germplasm for both germination at high temperatures and stand persistence in the field. This could lead to improved stand survival and greater adoption by southeastern forage producers.

Abstract	Increased salinity from irrigation and poor drainage has led to reduced production in semi‐arid and arid irrigated areas of the world. The narrow genetic variation among domestic barley (Hordeum vulgare L.) genotypes slows progress in developing varieties tolerant to biotic and abiotic stresses. A wild barley relative (H. bulbosum L.) is a genetic resource with tolerance to multiple stress conditions, especially salinity. New germplasm added to the USDA barley collection allows novel breeding opportunities. However, crosses between these species require embryo rescue. Crosses were made between diploid and tetraploidized domestic barley ♀ and tetraploid bulbous barley ♂. Immature embryos were rescued and placed on Murashige and Skoog (MS) or Gamborg's B‐5 (B‐5) media (no plant growth regulators, PGRs). Analysis of variance of families showed significant effects for the genotype × medium interactions, indicating each genotype responded to each medium type independently. Significant effects were observed for some traits due to both genotype and medium; and significant effects between media for some traits were observed indicating that those traits were affected by media type. Murashige and Skoog was found to be the better medium for most crosses compared to B‐5. Generally, results from this study indicated that it is difficult to draw broad conclusions about the most suitable medium composition for a broad spectrum of genotypes due to individual genotypes responding differently to the media type. Subsequent manuscripts by these authors will address the success of fertile crossed progeny.

Abstract	Forage production in the southeastern United States relies heavily on cool‐season grasses in winter and spring. The most prolific species is annual ryegrass (Lolium multiflorum Lam.), a winter annual. Historically, secondary seed dormancy of ryegrass inhibits germination at soil temperatures in excess of 21°C. Normal planting occurs in early‐mid fall (mid‐October). However, earlier planting (Aug. or Sept.) could expand the grazing period. This work sought use of recurrent phenotypic selection (RPS) to breed an annual ryegrass cultivar that could germinate at high temperatures and survive high temperatures post‐germination. All selections were conducted in a growth chamber at 40:30°C (12:12 h, light/darkness). Germinated seedlings were subjected to 2–3 wk of 40:30°C conditions post‐germination. Selected individuals (Cycle 1) and the base germplasm (Cycle 0) were transplanted to the field in fall 2015, and harvested for seed in spring 2016. Germination tests were conducted to compare mean cumulative germination, velocity of germination within 8 d (VOG₈), and realized heritability (h²) at 40:30°C. Selection was repeated twice to reach Cycle 3. Data from the 2018 germination tests indicated that germination of Cycle 3 seed (45.8%) was significantly greater (P < .001) within 14 d than that of all previous cycles. Cycle 3 VOG₈ was 8 times that of Cycle 0. Total additive gene action was estimated by a calculated realized heritability of h² = .41. These data indicate improved germination under high temperatures was achieved in nearly half the population. This will potentially allow for late‐summer planting and greater grazing time.
