“…Plant breeders are putting forth innovative strategies to deal with the growing need for food grains in the context of environmental problems such as rising global temperatures, irregular rainfall patterns, and concurrent changes in pest and disease attacks ( Figure 3 ). Resource depletion (land degradation, nutrient insufficiency, water availability) makes it even more important to enhance agriculture sustainably and reduce its CO 2 emission ( Mir et al., 2022 ). Increased temperatures and higher CO 2 levels, which are connected to the impoverished nutrient density of several staple crops, exacerbate the serious health issues encountered by billions of malnourished people in low-income regions ( Macdiarmid and Whybrow, 2019 ).…”

“…Recent developments have made it possible for molecular plant breeding to now uses integrated multi-omics approaches, allowing plant breeders to insert desired genetic variations in the crop genome from a larger gene pool with better accuracy and speed. Hence, molecular plant breeding techniques are being aggressively added to the traditional crop improvement methods to efficiently get the desired results ( Mir et al., 2022 ).…”

Crop production is the primary goal of agricultural activities, which is always taken into consideration. However, global agricultural systems are coming under increasing pressure from the rising food demand of the rapidly growing world population and changing climate. To address these issues, improving high-yield and climate-resilient related-traits in crop breeding is an effective strategy. In recent years, advances in omics techniques, including genomics, transcriptomics, proteomics, and metabolomics, paved the way for accelerating plant/crop breeding to cope with the changing climate and enhance food production. Optimized omics and phenotypic plasticity platform integration, exploited by evolving machine learning algorithms will aid in the development of biological interpretations for complex crop traits. The precise and progressive assembly of desire alleles using precise genome editing approaches and enhanced breeding strategies would enable future crops to excel in combating the changing climates. Furthermore, plant breeding and genetic engineering ensures an exclusive approach to developing nutrient sufficient and climate-resilient crops, the productivity of which can sustainably and adequately meet the world’s food, nutrition, and energy needs. This review provides an overview of how the integration of omics approaches could be exploited to select crop varieties with desired traits.

“…Newer emerging molecular markers, also known as next-generation molecular markers are expected to accelerate crop improvement programs ( Mir et al, 2022 ). For instance, new markers including structural variations (SVs) and k-mers are believed to be extremely useful in GWAS and in other gene discovery programs ( Mir et al, 2022 ). New genomics tools are continuously evolving.…”

“…New genomics tools are continuously evolving. For instance, whole-genome re-sequencing (WGRS), QTL sequencing (QTL-Seq) and restriction site-associated DNA (RAD) genotyping have recently emerged and have revolutionized the gene discovery programs and therefore crop improvement programs ( Mir et al, 2013a ; Mir and Varshney 2013 ; Mir et al, 2022 ). The first set of tools for fine mapping of genes/QTLs influencing economically significant quantitative traits, such as biotic/abiotic stressors and agricultural yields, are reference genomes, transcriptomes, and molecular markers ( Barmukh et al, 2022 ).…”

“…Breeders have bred a large number of varieties to cope with the crises that may be encountered during plant growth. In breeding efforts, germplasm resources with excellent traits such as high yield (Fukushima et al, 2011), resistance to specific diseases or insects (Mir et al, 2022), and tolerance to abiotic adversity are crucial (Vahdati et al, 2009). Studying the excellent traits possessed by these varieties, analyzing their physiological and molecular mechanisms, mining the key genes, and breeding or transforming them so that the excellent traits are stably inherited to future generations are often the keys to breakthroughs in breeding efforts (Timerbaev et al, 2019;Mou and Zhao, 2022).…”

Drought is one of the major abiotic stress factors limiting soybean growth and yield, and it frequently occur globally. Therefore, exploring resistant varieties from soybean germplasm is important under climate change. To screen drought resistant spring soybean varieties at seedling stage, pot experiment was used to detect the Survival percentage after drought stress of 60 soybean varieties at seedling stage, twice drought rehydration treatments on seedlings, to evaluate the drought tolerance of spring soybean. The results showed that at the seedling stage, seven varieties were considered drought tolerant, 17 varieties were considered drought sensitive, and 36 varieties were considered to be moderately drought tolerant. Based on this experiment, number 44 (heinong37), 48 (heinong44), 49 (heinong45), 52 (heinong48) is considered the best drought resistant, and number 3 (dongnong48), 4 (dongnong52), 27 (suinong25), 60 (heinong65) is the most sensitive. These varieties provide a reference for further study on drought tolerance and stress resistance gene screening of soybean at the molecular level. The selected soybean varieties can be planted in areas with suitable climates and frequent drought to meet the local soybean demand. In other regions, although cannot be directly grown, they can still be used as parents of selected varieties or as materials for gene screening and extraction, to assist crop breeding at the molecular level in response to increasingly severe drought stress problems under the current climate trends.
