Cai R.X., 2024, Breeding Triticale for stress-prone environments: genetic insights and methodologies, Triticeae Genomics and Genetics, 15(5): 277-286 (doi: 10.5376/tgg.2024.15.0026)

Triticale, a hybrid cereal combining the qualities of wheat and rye, has become a key focus in crop breeding for stress-prone environments. This paper discusses recent advancements in Triticale breeding methodologies and improving stress tolerance, with a focus on the application of molecular genetics, biotechnology, and hybrid breeding techniques. Key topics covered include genomic tools such as genome-wide association studies (GWAS), marker-assisted selection (MAS), and the use of CRISPR/Cas9 gene editing to enhance resilience against abiotic and biotic stresses. The integration of high-throughput phenotyping and multi-omics approaches has provided deeper insights into the physiological and molecular responses of Triticale to environmental challenges. Additionally, strategies to overcome genetic bottlenecks, balance trade-offs between yield, quality, and stress tolerance, and develop sustainable, low-input cropping systems are examined. The paper emphasizes the role of Triticale in ensuring food security in the context of climate change and highlights future directions for research and innovation in breeding programs to meet the demands of increasingly challenging agricultural environments.
