Context Post-anthesis heat stress is a major concern for wheat. Stay-green (SG) can serve as crucial marker plant adaptation to it. Though genetic resources provide an invaluable gene pool crop breeding, collections are still uncharacterised and their potential yet be explored. Aims This study was planned characterise evaluate wheat resources, including wild germplasm, tolerance using SG traits selection criteria. Methods Experiment conducted with thirty genotypes under late very sown environments 2 years. Genotypes were assessed like Normalised Difference Vegetation Index (NDVI), Soil Plant Analysis Development Chlorophyll Meter Reading (SCMR), Leaf Senescence Rate (LSR), chlorophyll fluorescence (Fv/Fm), canopy temperature (CT), phenological traits, morphological yield its attributes; characterised into three categories viz., slow senescing, intermediate senescing fast based on rate of senescence. Key results Results indicate that slow-senescing had significantly higher NDVI, SCMR compared fast-senescing genotypes. SCMR, Fv/Fm, days heading, anthesis, maturity, grain weight per spike, 100-grain biomass positively correlated whereas LSR CT negatively yield. From the principal component analysis studies, it revealed high low LSR, placed together Conclusions confirms performed better stress. Implications wild, HTW 11 (W), 67 (W) 6 utilised breedings.

Rust diseases are among the major constraints for wheat production worldwide due to emergence and spread of highly destructive races Puccinia. The most common approach minimize yield losses rust is use cultivars that genetically resistant. Modern cultivars, landraces, wild relatives can contain undiscovered resistance genes, which typically encode kinase or nucleotide-binding site leucine rich repeat (NLR) domain containing receptor proteins. Recent research has shown these genes provide either in all growth stages (all-stage resistance; ASR) specially later (adult-plant APR). ASR pathogen race-specific, meaning function against selected Puccinia fungus necessity recognize specific avirulence molecules pathogen. APR pathogen-specific multipathogen resistant but often race-nonspecific. Prediction through infection screening alone remains complex when more than one gene present. However, breakthroughs during past half century such as single-nucleotide polymorphism-based genotyping techniques isolation strategies like mutagenesis, enrichment, sequencing (MutRenSeq), mutagenesis chromosome (MutChromSeq), association genetics combined with RenSeq (AgRenSeq) enables rapid transfer from source modern cultivars. There a strong need combining multiple better efficacy longer-lasting resistance. Hence, cassette creation speeds up combination process, their widespread adoption commercial limited transgenic nature.

Global agricultural productivity and food security are threatened by climate change, the growing world population, difficulties posed pandemic era. To overcome these challenges meet requirements, breeders have applied implemented different advanced techniques that accelerate plant development increase crop selection effectiveness. However, only two or three generations could be annually using approaches. Speed breeding (SB) is an innovative promising technology to develop new varieties in a shorter time, utilizing manipulation of controlled environmental conditions. This strategy can reduce generation length from 2.5 5 times compared traditional methods advancement improvement, accommodating multiple crops per year. Beside long cycles, SB address other related breeding, such as response conditions, disease pest management, genetic uniformity, improving resource efficiency. Combining genomic approaches marker-assisted selection, genome editing with offers capacity further enhance efficiency reducing cycle enabling early phenotypic assessment, efficient utilization, increasing accuracy gain Genomics-assisted holds potential revolutionize significantly accelerating identification desirable traits, expediting improved crucial for addressing global challenges.

Abstract Farming practices of the past century have dramatically increased annual crop yields to unprecedented levels but consequentially created increasing ecological and public health concerns, posing a long‐term threat global food security. Soil tillage chemical inputs perpetuate soil erosion, biodiversity loss, wetlands eutrophication, carbon emissions, other farming stressors. Concomitantly, accompanying poor dietary patterns malnutrition increase risk for chronic diseases, such as cardiovascular obesity, type 2 diabetes, cancer, which account greater than 70% mortality per annum. Altogether, monocropping systems exacerbate insecurity, necessitating action across fields health, agriculture, nutrition, medicine, environmental ecology, that is, transdisciplinary approach. Herein, we argue perennialization crops creates an opportunity address challenges sustainability nutritional adequacy economically. Unlike annuals, perennial deeper roots drought tolerance reduced needs fertilization irrigation. Adopting perenniality can result in improved while reducing labor, seed purchasing. Furthermore, perennializing novel staple may offer superior diverse profile phytochemicals, fiber, macronutrients compared conventional annuals.

Abstract Wheat is one of the most important cereal crops grown in Western Himalayas India but its production challenged by insect “cereal leaf beetle (CLB)”. This study explores impact domestication and modern crop improvement on wheat's defense mechanisms against CLB, a global threat to wheat cultivation. Sixteen diverse genotypes having different ploidy levels were investigated, including wild wheat, landraces, mutants, advanced breeding lines, commercial varieties, Rye grass genotype. Genotypes with resistance genes, exhibited lowest CLB infestation oxidative damage. These displayed enhanced antioxidant enzyme activity, such as peroxidase (POD), ascorbate (APX), catalase (CAT), superoxide dismutase (SOD), polyphenol oxidase (PPO), reduced reactive oxygen species (ROS) production, increased plant secondary metabolite (phenol tannin) upon infestation. Resistant durum demonstrated moderate responses higher flavonoid production. On other hand, susceptible genotypes, variety Shalimar Wheat‐02 (SW‐2), showed high infestation, ROS may be because varieties like SW‐2 not selected for resistance. findings emphasize significance preserving genetic diversity from landraces bolster programs pests CLB. underscores need harness ancestral lines enhance pest cultivars.
