Modern breeding technologies and the development of quantitative trait locus (QTL) mapping have brought about a new era in peach breeding. This study examines complex genetic structure that underlies morphology fruits, paying special attention to interaction between genome editing, genomic selection, marker-assisted selection. Breeders now access precise tools enhance crop resilience, productivity, quality, facilitated by QTL mapping, which has significantly advanced our understanding determinants underlying essential traits such as fruit shape, size, firmness. New like CRISPR/Cas9 selection enable cultivars can withstand climate change satisfy consumer demands with unprecedented precision modification. Genotype-environment interactions remain critical challenge for modern efforts, be addressed through high-throughput phenotyping multi-environment trials. work shows how combining genome-wide association studies machine learning improve synthesis multi-omics data result faster cycles while preserving diversity. outlines roadmap prioritizes superior utilizing cutting-edge methods order address evolving agricultural environmental challenges.

Abstract Dietary fiber is widely recognized for its beneficial effects on human health, and sesame ( Sesamum indicum L.) seeds are an important source of dietary fiber. However, efforts to improve higher have been constrained by limited knowledge the genetic factors underlying this trait. In study, we identified a strong correlation between sugar content, both which significantly influenced factors. A large‐scale analysis 222 germplasm resources revealed genome‐wide single nucleotide polymorphism n = 1,535,018), insertions deletions (InDels; 325,371), structure variations (SVs; 29,028). Linkage disequilibrium association studies InDel quantitative trait locus targeting SiLAC3 gene, caused gene frameshift mutation associated with traits. Furthermore, 1201‐bp deletion SV in coding 3′ untranslated regions SiXTH30 was high content. Notably, two accessions (CX150 CX546) pyramiding favorable alleles these mutated genes exhibited significant increase content compared only one allele. We also found candidate highly expressed during early middle stages seed development, previously reported play roles cell wall conclusion, our findings highlight key fiber‐associated genes, could serve as valuable molecular breeding aimed at increasing seeds.
