Hybrid rice typically surpasses conventional in terms of biomass, yield, and stress resistance, whereas developing utilizing saline–alkali-tolerant hybrid is crucial to obtain crop harvests from salt-affected soils. In the present study, varieties (paternal parents), i.e., Hua-Zhan 9311, four varieties, Xiang-Liang-You-Hua-Zhan, Jing-Liang-You-Hua-Zhan, Guang-8-You-Hua-Zhan, Y-Liang-You-1-Hao, denoted as V1, V2, V3, V4, V5, V6, respectively, received an application two salt levels, 0% 0.3% saltwater irrigation, during 2022–2023. The results reveal that V1 (parental parent) had highest tolerance index, which was significantly greater than its V5. Moreover, index V2 also (V6). lower might be owing relative loss number effective panicles, total grains per panicle, seed setting rate, thousand-grain weight. our study revealed appearance different enhanced at a concentration 0.3%. Among all cultivars, largest reductions chalkiness chalky grain rate were observed 81.13% 63.49%, well 84.03% 87.53%, respectively. protein sodium contents sodium-potassium ratio cultivars increased under stress; however, no significant effect on cooking or sensory quality noticed saline conditions. Overall, negatively affected yield quality, but more salt-tolerant rice, harnessing heterosis improve saline-tolerant rice.

Soil salinity represents a significant factor affecting agricultural productivity and crop quality. The present study was conducted to investigate the effects of soil conditioner (SC) comprising halotolerant microorganisms on fertility, yield, rice quality, physicochemical structural properties starch in hybrid under saline conditions. experimental treatments were composed two high-quality varieties, i.e., ‘Y Liangyou 957’ (YLY957) Jing 534 (JLY534), amendment treatments, application SC at control levels 2250 kg hm−2, or ‘CK SC’, respectively. subjected mixture fresh sea water (EC 11 dS/m). results demonstrated that significantly enhanced yield salt stress conditions owing an increase number grains per panicle. Furthermore, found be effective improving organic matter nutrient content. resulted improvement antioxidant defense, higher leaf SPAD values, greater biomass, as well translocation photo-assimilates heading stage. not only improved milling appearance quality but also taste value by increasing amylose reducing protein decreased indentations surfaces granules cracks edges granules. varieties exhibited excellent pasting properties, characterized reduced proportions amylopectin short chains lower gelatinization temperature enthalpy gelatinization. Overall, these findings serve reinforce efficacy valuable tool improve sustainability with grain

Saline-alkali stress is a major abiotic factor that adversely affects the growth, development, and yield of crops by disrupting ion homeostasis, osmotic balance, metabolic processes. This study was designed to explore alleviating effect melatonin on growth development tomato plants under saline-alkali conditions screen for optimal concentrations alleviate stress. Tomato variety 'Condine Red' used as test material, total six treatments were including no spray control (CK), foliar spraying 0, 50, 100, 150, 200 µmol·L− 1 (75 mmol·L− 1), which determine photosynthetic characteristics plants. The results showed significantly inhibited plant height, stem diameter, root activity biomass accumulation, reduced chlorophyll content leaves efficiency electron transfer from primary quinone receptor QA secondary QB, caused significant deformation fast fluorescence induced kinetic curve (OJIP), inhibiting photosynthesis. Exogenous could improve tolerance stress, depended concentration. In this experiment, treatment with 100 strongest positive according comprehensive evaluation principal components. addition, changes in parameters induction curves after highlighted response system enhancing quenching excess excitation energy protecting transport system. Collectively, exogenous pretreatment increased activity, improved photosystem processes, thereby lay foundation practical application

Climate change is a global concern for agriculture, food security, and human health. It affects several crops causes drastic losses in yield, leading to severe disturbances the economy, environment, community. The consequences on important staple crops, such as rice, maize, wheat, will worsen create insecurity across globe. Although various methods of trait improvements are available being used, clustered regularly interspaced short palindromic repeats CRISPR-associated protein 9 (CRISPR/Cas9) mediated genome manipulation have opened new avenue functional genomics crop improvement. This review discuss progression improvement from conventional breeding advanced editing techniques how CRISPR/Cas9 technology can be applied enhance tolerance main cereal (wheat, maize) against any harsh climates. CRISPR/Cas endonucleases their derived genetic engineering tools possess high accuracy, versatile, more specific, easy design, climate-smart or resilient combat survive environments. CRISPR/Cas9-mediated approach has been make them climate resilient. review, supported by bibliometric analysis recent literature, highlights potential target genes/traits addresses significance gene technologies tackling vulnerable effects major maize.

Brown rice over-milling causes high economic and nutrient loss. The degree of milling (DOM) detection prediction remain a challenge for moderate processing. In this study, self-established grain image acquisition platform was built. Degree bran layer remaining (DOR) datasets is established with capturing processing (grain color, texture, shape features extraction). mapping relationship between DOR the DOM in-depth analyzed. Rice typical machine learning deep models are established. results indicate that optimized Catboost model can be cross-validation grid search method, best accuracy improving from 84.28% to 91.24%, achieving precision 91.31%, recall 90.89%, F1-score 91.07%. Shapley additive explanations analysis indicates feature affect accuracy, importance: color > texture shape. YCbCr-Cb_ske GLCM-Contrast make most significant contribution quality prediction. importance provides theoretical practical guidance model. PRACTICAL APPLICATION: valuable process in application. paper, methods provide an automated, nondestructive, cost-effective way predict rice. study may serve as reference methods, retaining nutrition, reducing broken yield.

Soda saline–alkaline stress significantly impedes the rice grain filling process and ultimately impacts yield. Biochar has been shown to mitigate negative of on plants. However, exact mechanism by which biochar influences grain-filling rate in soda soil is still not fully understood. A two-year field experiment was conducted with two nitrogen fertilizer levels (0 225 kg ha−1) five application rates [0% (B0), 0.5% (B1), 1.5% (B2), 3.0% (B3), 4.5% (B4) biochar, w/w]. The results demonstrated that had a significant impact reducing Na+ concentration Na+/K+ ratio grown lands, while also improving its physiological conditions. B1, B2, B3, B4 showed notable increase average 5.76%, 6.59%, 9.80%, 10.79%, respectively, compared B0; time reach maximum weight saw increases ranging from 6.02% 12.47% 7.85% 14.68%, respectively. Meanwhile, particularly when used conjunction fertilizer, notably enhanced activities sucrose synthase (SuSase), ADPG pyrophosphorylase (AGPase), starch (StSase), branching enzyme (SBE) grains lands. Furthermore, yield increased 11.95–42.74% treatments B0 treatment. These findings improves regulating ionic balance, indicators, synthesis key activities, paddy fields.
