“…Production (Million Tons/Year) Phenotyping and high throughput genotyping technology have also sped up the process of finding resistant alleles and introducing them into elite germplasm. Breeders may now quickly identify genomic areas linked to resistance features and accelerate the creation of resistant cultivars using genome-wide association studies (GWAS) and genomic selection [9]. Genetic resources from landraces and wild relatives in wheat have been essential in widening the genetic diversity for disease resistance.…”

Current developments in plant breeding techniques used to improve cereals resistance against biotic stress. To overcome the problems provided by biotic stress, the focus is on investigating cutting-edge strategies and techniques that have transformed the area of cereal breeding. The creation of biotic stress-resistant varieties has been greatly accelerated by the introduction of Marker-Assisted Backcrossing (MABC), which enables the controlled transfer of advantageous genes from wild germplasm into elite cultivars. To better understand the genetic basis of resistance traits and support marker-assisted selection in breeding programs, Genome-Wide Association Studies (GWAS) have been useful in identifying genetic markers linked to biotic stress resistance. Researchers have been able to decipher intricate gene regulatory networks involved in plant responses against biotic stress using microarray technique; which leads to identifying critical genes and pathways underlying resistance mechanisms. New possibilities for precise genetic alterations in genomes, including as the introduction of novel resistance alleles using allele mining and the targeted disruption of susceptibility genes, have been made possible by genome editing tools like CRISPR/Cas9. Apart from these modern-day techniques, conventional methods such as mutation breeding are still being improved and combined with genomic technologies to create genetic variation and find new alleles that confer resistance to biotic stress. A promising method such as targeted gene silencing and RNA interference (RNAi) technology enables the suppression of genes linked to biotic stress susceptibility and also increases resistance. The improvement of cereal crop varieties resistant against biotic stress has advanced significantly due to the integration of these many breeding tactics and technologies. These new developments have the potential to significantly improve agricultural sustainability and food security by reducing yield losses from biotic stressors and supporting international efforts to improve crops. This review article enlightens the different conventional and advanced breeding techniques used against biotic stress found in cereal crops.

“…Limited literature stating utilization of genomic selection for rice breeding indicates the scope for utilizing the approach in rice breeding (Anilkumar, Sah, Muhammed, et al, 2022). The method is not much exploited in drought resistance breeding in rice till date; however, GS is a promising method for prediction of promising individuals carrying complex genetic architecture for drought tolerance in rice (Anilkumar, Lokeshkumar, Sunitha, et al, 2022). However, this method is demonstrated to be useful in improving selection accuracy for complex traits like agronomic traits and yield in rice breeding (Anilkumar et al, 2023; Xu et al, 2018).…”

Drought is becoming a major threat to rice farming across the globe owing to the depletion of water tables in rice‐growing belts. Drought affects rice plants at multiple stages, causing damage at morphological and physio‐biochemical levels, leading to severe losses that exceed losses from all other stresses. The amalgamation of conventional breeding methods with modern molecular biology tools and biometrical methods could help accelerate the genetic gain for drought tolerance in rice. Many drought‐tolerance traits with genetic determinants have been identified and exploited for tolerance rice variety breeding. The integration of genome‐wide association study and genomic selection tools with speed breeding shortened the breeding cycle and aided in rapid improvement of genetic gain. In this review, we emphasized the progress made through classical breeding as well as the limitations and usefulness of current genomic methods in improving drought tolerance. We briefly addressed methods for identifying genetic determinants for drought tolerance and deploying them through genomics‐assisted breeding programmes to develop high‐yielding drought‐tolerant rice cultivars.
