Marker-assisted selection (MAS) plays a crucial role in crop breeding improving the speed and precision of conventional programmes by quickly reliably identifying selecting plants with desired traits. However, efficacy MAS depends on several prerequisites, precise phenotyping being key aspect any plant programme. Recent advancements high-throughput remote phenotyping, facilitated unmanned aerial vehicles coupled to machine learning, offer non-destructive efficient alternative traditional, time-consuming, labour-intensive methods. Furthermore, relies knowledge marker-trait associations, commonly obtained through genome-wide association studies (GWAS), understand complex traits such as drought tolerance, including yield components phenology. GWAS has limitations that artificial intelligence (AI) been shown partially overcome. Additionally, AI its explainable variants, which ensure transparency interpretability, are increasingly used recognised problem-solving tools throughout process. Given these rapid technological advancements, this review provides an overview state-of-the-art methods processes underlying each MAS, from genotyping analyses integration along entire workflow. In context, we specifically address challenges importance winter wheat for greater tolerance stable yields, regional droughts during critical developmental stages pose threat production. Finally, explore transition scientific progress practical implementation discuss ways bridge gap between cutting-edge developments breeders, expediting MAS-based tolerance.

The sugarcane ratooning ability (RA) is the most important target trait for breeders seeking to enhance profitability of production by reducing planting cost. Understanding genetics governing RA could help identifying molecular markers that be used genomics-assisted breeding (GAB). A replicated field trial was conducted three crop cycles (plant cane, first ratoon, and second ratoon) using 432 clones conducting genome-wide association genomic prediction five sugar yield component traits RA. economic index (EI), stalk population (SP), weight (SW), tonns cane per hectare (TCH), sucrose (TSH) were estimated from data. total six putative quantitative loci eight nonredundant single-nucleotide polymorphism (SNP) associated with all tested appear unique. Seven candidate genes colocated significant SNPs traits. accuracies those moderate ranged 0.21 0.36. However, models fitting fixed effects each respective did not give any advantages over standard without effects. As a result this study, more robust in future clone selection sugarcane, potentially helping resolve genetic control sugarcane.
