Genetic effects of physiological and morpho-agronomic traits in popcorn under water stress Marcelo VIVAS, Lauro José Moreira GUIMARÃES, Monique DE SOUZA SANTOS, Eliemar CAMPOSTRINI, Flávia Nicácio VIANA, et al. Frontiers of Agricultural Science and Engineering, 2026 Understanding the genetic basis of agronomic, morphological and physiological traits in popcorn is key to developing effective breeding strategies under water-limited conditions. This study evaluated additive and dominance effects on 25 traits in 10 S7 inbred lines and their 45 diallel hybrids under water-stressed and well-watered conditions. Water stress was applied 15 days before male flowering by ceasing irrigation. Significant genetic variability was observed, with reductions in grain mass and popping expansion under water stress. Normalized difference vegetation index and relative chlorophyll content effectively detected phenotypic differences during critical growth stages, while canopy temperature depression provided insights into stomatal closure. Some genotypes possessed greater drought resilience, maintaining high chlorophyll levels, associated with the stay-green trait, extending active photosynthesis and increasing biomass accumulation. Dominance effects were predominant for most traits, except for popping expansion and stem diameter, where additive effects were slightly higher under both water regimes. Lines L76, L61 and P3 had high potential for grain yield and drought tolerance. Hybrids L61 × L76 and L71 × L76 performed well under both watering treatments, underscoring the role of heterosis due to dominant allelic interactions. This research highlights the importance of exploring genetic variation for yield and drought-related traits, offering insights for developing popcorn cultivars resilient to water stress.
Early Selection of Popcorn Lines for Tolerance to Salt Stress Rosenilda de Souza, Henrique Duarte Vieira, Samuel Henrique Kamphorst, Valter Jário de Lima, Ellen Peixoto Azeredo, Antônio Teixeira do Amaral Junior Stresses, 2026 The evaluation of popcorn lines for salt stress during the germination phase facilitates the early selection of superior genotypes, ensuring crop success. This study assessed 31 lines to identify genotypes tolerant to salt stress in the early phase and to understand the effects. Seeds were sown on paper substrate with two concentrations of sodium chloride: zero (NS) and 100.0 mM (SS), in a randomized block design with four replicates of 25 seeds each. Physical and physiological traits of seeds and seedlings were evaluated. Analysis of variance revealed significant effects (p ≤ 0.01) for genotype, salinity condition, and their interaction. Genetic variability was observed under both conditions. In NS, area and germination were the most influential factors in differentiating lines, while in SS, total seedling length and the percentage of abnormal seedlings were key. The stress tolerance index identified lines L263, L684, L472, and L358 as the most tolerant, and lines L690, L217, L220, and L213 as the most sensitive. Tolerant genotypes are potential candidates for crossbreeding aimed at developing hybrids adapted to salinity conditions, promoting agricultural sustainability in adverse environments. The significant interaction between genotypes and salinity conditions reinforces the importance of conducting selection in specific stress environments.
Water-Use Efficiency and Responsiveness of a Popcorn Panel Grown Under Different Water Regimes and Cropping Seasons Monique de Souza Santos, Samuel Henrique Kamphorst, Antônio Teixeira do Amaral Junior, Jhean Torres Leite, Valter Jário de Lima, Uéliton Alves de Oliveira, Christiane Mileib Vasconcelos, Flávia Nicácio Viana, Talles de Oliveira Santos, Gabriella Rodrigues Gonçalves, Rogério Figueiredo Daher, Cosme Damião Cruz, Eliemar Campostrini Agronomy, 2026 Climate change has intensified drought events, compromising popcorn production, particularly in tropical regions. This study aimed to identify popcorn inbred lines with superior water-use efficiency and responsiveness, and to examine the relationships among morpho-agronomic traits associated with expanded popcorn volume per hectare (VP). Fifty inbred lines were evaluated under well-watered (WW) and water-stressed (WS) conditions across two cropping seasons (2020 and 2021). Water deficit was imposed at pre-anthesis, with the permanent wilting point occurring during early reproductive stages in 2020 and during grain filling in 2021. Principal component analysis and efficiency/responsiveness classification were used to characterize line performance. Significant genotype × water condition × season interactions affected all traits. Water stress reduced VP by 75% in 2020 and 46% in 2021, reflecting the differing timing of stress. Line L477 showed high efficiency and responsiveness, while genotypes such as L213, L221, and L222 were inefficient and non-responsive in both years. Under WW, VP was mainly associated with hundred-grain weight, ear length, and grain number per row, whereas under WS, ear diameter and number of rows per ear were the strongest contributors, indicating that the available genetic variability is more effectively exploited through selective morpho-agronomic criteria tailored to each water scenario. Contrasting crosses between efficient and non-responsive lines (L325 and L481) and inefficient but responsive lines (L513, L625, and L689) are recommended to support the development of hybrids that combine high yield under irrigation with resilience under water-stress conditions.
Growth and Physiological Traits Associated with Water Use Efficiency in Different Popcorn Genotypes Grown Under Water-Stress Conditions Emile Caroline Silva Lopes, Paulo Ricardo dos Santos, Luciene Souza Ferreira, Guilherme Augusto Rodrigues de Souza, Weverton Pereira Rodrigues, Samuel Henrique Kamphorst, Valter Jário de Lima, Deivisson Pelegrino de Abreu, Antônio Teixeira do Amaral Junior, Eliemar Campostrini Crops, 2025 Climate change may soon impact popcorn productivity. The aim was to assess physiological and growth traits in two popcorn genotypes with different water use efficiency under water-deficit stress. The plants were grown in a greenhouse under either water stress (WS) or non-water stress (WW) conditions. Gas exchange, chlorophyll fluorescence, and leaf temperature were assessed every three days, for a total of nine measurements. At the end of the assessment period, growth traits and the SPAD index were evaluated. Our hypotheses were as follows: (a) plants of the P7 genotype (water-efficient agronomic genotype) would take longer than L65 plants (water-inefficient agronomic genotype) to reduce photosynthetic rates under water stress conditions; (b) after re-irrigation, P7 plants would recover photosynthetic capacity with values similar to the period without water stress; and (c) P7 plants would recover photosynthetic capacity faster than L65 plants when subjected to the same period of water stress. The P7 genotype (agronomic water-efficient genotype) absorbed water more quickly due to higher root biomass, root length, and root volume. Yet, at 14 days after suspending irrigation (DASI), the P7 genotype had the lowest net CO2 assimilation rate (Anet), stomatal conductance (gs), and transpiration rates (E) values. However, L65 (agronomic water-inefficient genotype) had the lowest Anet, gs, and E values only at 17 DASI. As a consequence of stomatal closure in both genotypes, the E rates were reduced, and there was an increase in leaf temperature for WS plants, while L65 had higher leaf temperature at maximum water stress. No photochemical damage was detected, indicating that the reduced Anet in WS was likely due to stomatal limitations and biochemical disturbances in both genotypes. Photosynthetic recovery occurred gradually, with full restoration of rates in both genotypes at the end of the experiment. Although our initial hypothesis expected the P7 genotype to maintain photosynthesis longer under water stress, our findings showed an earlier decline in Anet compared to L65. This result is likely due to the large root system of P7 exhausting the limited soil water more rapidly in pot conditions, accelerating the onset of stress.
Morphophysiological approach to heterosis in phosphorus use efficiency in popcorn Rosimeire Barboza Bispo, Antônio Teixeira do Amaral Junior, Talles de Oliveira Santos, Valter Jário de Lima, Bruna Rohem Simão, Marta Simone Mendonça Freitas, Samuel Henrique Kamphorst, Carolina Macedo Carvalho, Danielle Leal Lamêgo, Flávia Nicácio Viana, Wallace de Paula Bernardo, Eliemar Campostrini, Ricardo Bressan-Smith Cogent Food and Agriculture, 2025 The development of cultivars adapted to phosphorus (P) deficiency is crucial due to the non-renewable nature of this resource. Although heterosis is widely utilized in maize to enhance productivity, studies on the physiological mechanisms of heterosis expression in popcorn maize under P deficiency remain limited, as do investigations of genetic control during the juvenile phase. This study evaluated the genetic control and heterosis effects on growth traits, gas exchange, leaf pigments, chlorophyll fluorescence, and P efficiency in four popcorn maize inbred lines and their hybrids, including reciprocals. Plants were grown in lysimeters under two contrasting P conditions until the V6 stage in a greenhouse. P deficiency reduced most traits, with dominance gene effects predominantly controlling morphophysiological traits and P efficiency under low P. Greater heterosis effects were observed for growth traits like aerial and root dry weight, root P content, and P efficiency under low P. Phosphorus utilization efficiency (PUtE) improved hybrid performance in phosphorus use efficiency (PUE), while higher instantaneous carboxylation efficiency (A/Ci) enhanced net CO2 assimilation rate (A) under P deficiency.
UENF EXPLOSÃO: A popcorn cultivar featuring superior yielding potential and moderate resistance to polysora rust Antônio Teixeira do Amaral Júnior, Divino Rosa dos Santos, Valter Jário de Lima, Samuel Henrique Kamphorst, Talles de Oliveira Santos, et al. Crop Breeding and Applied Biotechnology, 2025 Abstract UENF EXPLOSÃO single-cross hybrid is a popcorn cultivar (Zea mays var. everta) developed by the Universidade Estadual do Norte Fluminense Darcy Ribeiro. It was released in 2019 for cultivation in Rio de Janeiro. This cultivar stands out for its superior productivity, offering a promising alternative for the agricultural sector.
Gene Effect of Morphophysiological Traits in Popcorn (Zea mays L. var. everta) Grown Under Contrasting Water Regimes Danielle Leal Lamêgo, Antônio Teixeira do Amaral Junior, Samuel Henrique Kamphorst, Valter Jário de Lima, Samuel Pereira da Silva, Jardel da Silva Figueiredo, Ueliton Alves de Oliveira, Flávia Nicácio Viana, Talles de Oliveira Santos, Gabriella Rodrigues Gonçalves, Guilherme Augusto Rodrigues de Souza, Eliemar Campostrini, Alexandre Pio Viana, Marta Simone Mendonça Freitas, Helaine Christine Cancela Ramos, Gonçalo Apolinário de Souza Filho, Carlos Eduardo de Rezende Agriculture Switzerland, 2024 To propose breeding strategies for drought conditions, we investigated gene expression associated with morphophysiological traits in four S7 popcorn (Zea mays var. everta) inbred lines using a partial diallel cross design with two testers. We evaluated morphological traits (plant height; the dry mass of stems, leaves, and reproductive organs; and root weight density (RWD) across five soil sections), water status indicators (leaf water content, cumulative evapotranspiration, agronomic water use efficiency, and carbon isotope signatures), anatomical traits (stomatal number and index), and leaf pigments. Significant variations were observed between lines and hybrids for plant height, shoot biomass traits, water status indicators, and RWD across all soil sections, particularly under water deficit conditions. Overall, the inbred lines were more adversely affected by drought than the hybrids. Dominance gene effects played a significant role in increasing anthocyanin content, cumulative evapotranspiration, stable carbon isotope signatures, and RWD in most soil sections. The superior water utilization observed in hybrids compared to inbred lines suggests that exploiting heterosis is likely the most effective strategy for developing drought-resilient popcorn plants.
Bacillus cereus: An Ally Against Drought in Popcorn Cultivation Uéliton Alves de Oliveira, Antônio Teixeira do Amaral Junior, Samuel Henrique Kamphorst, Valter Jário de Lima, Fábio Lopes Olivares, Shahid Khan, Monique de Souza Santos, Jardel da Silva Figueiredo, Samuel Pereira da Silva, Flávia Nicácio Viana, Talles de Oliveira Santos, Gabriella Rodrigues Gonçalves, Eliemar Campostrini, Alexandre Pio Viana, Freddy Mora-Poblete Microorganisms, 2024 Despite the development of adapted popcorn cultivars such as UENF WS01, strategies such as bacterial inoculation are being explored to enhance plant resilience to abiotic stress. This study investigates the impact of drought stress on popcorn cultivation. Specifically, the aim was to identify the benefits of Bacillus cereus interaction with the drought-tolerant hybrid UENF WS01 for its morphophysiology and growth by comparing inoculated and non-inoculated plants under water-stressed (WS) and well-watered (WW) conditions. This evaluation was conducted using a randomized complete block design in a factorial arrangement. For WS with inoculation samples, there were significant increases in relative chlorophyll content, maximum fluorescence intensity, and agronomic water use efficiency. Chlorophyll content increased by an average of 50.39% for WS samples, compared to a modest increase of 2.40% for WW samples. Both leaf and stem biomass also significantly increased for WS relative to WW conditions. Overall, B. cereus inoculation mitigated the impact of water stress, significantly enhancing the expression of physiological and morphological traits, even when paired with a drought-tolerant hybrid.
Utilizing Visible Band Vegetation Indices from Unmanned Aerial Vehicle Images for Maize Phenotyping Guilherme Gonçalves Coswosk, Vivane Mirian Lanhellas Gonçalves, Valter Jário de Lima, Guilherme Augusto Rodrigues de Souza, Antônio Teixeira do Amaral Junior, Messias Gonzaga Pereira, Evandro Chaves de Oliveira, Jhean Torres Leite, Samuel Henrique Kamphorst, Uéliton Alves de Oliveira, Jocarla Ambrosim Crevelari, Késia Dias dos Santos, Frederico César Ribeiro Marques, Eliemar Campostrini Remote Sensing, 2024 Recent advancements in high-throughput phenotyping have led to the use of drones with RGB sensors for evaluating plant traits. This study explored the relationships between vegetation indices (VIs) with grain yield and morphoagronomic and physiological traits in maize genotypes. Eight maize hybrids, including those from the UENF breeding program and commercial varieties, were evaluated using a randomized block design with four replications. VIs were obtained at various stages using drones and Pix4D Mapper 4.7.5 software. Analysis revealed significant differences in morphoagronomic traits and photosynthetic capacity. At 119 days after planting (DAP), the RGB vegetation index VARI showed a significant correlation (r = 0.99) with grain yield. VARI also correlated with female flowering (r = −0.87), plant height (r = −0.79), 100-grain weight (r = −0.77), and anthocyanin concentration (r = −0.86). PCA showed a clear separation between local and commercial hybrids, explaining 46.7% of variance at 91 DAP, 52.3% at 98 DAP, 64.2% at 112 DAP, and 66.1% at 119 DAP. This study highlights the utility of VIs in maize phenotyping and genotype selection during advanced reproductive stages.
