Abstract

The mapping populations have contributed significantly to the understanding of genes underlying a trait. Genetic mapping is facilitated by diverse populations, such as F2, RILs, and MAGIC, with state-of-the-art, high-throughput genotyping technologies to identify and analyse quantitative trait loci more precisely. These developments enable marker-assisted and genomic selection for the development of crops with higher yields and better resistance. This would include key contributions of refined QTL mapping techniques, improvement in trait resolution by multi-parental populations, and integration of multi-environment trials for assessing genotype-by-environment interactions. To address agricultural challenges and achieve sustainable food production, future efforts should concentrate on enhancing mapping resolution through advanced genomics tools, functional gene editing, and cross-species comparisons.
