A new genome mapping model uncovered 62 key trait loci in bananas, overcoming chromosomal barriers and aiding future crop improvement across complex plant genomes. Bananas are a dietary staple for millions of people, but their cultivation faces serious threats due to limited genetic diversity and significant breeding challenges. In a major scientific breakthrough, researchers examined more than 2,700 triploid banana hybrids to uncover the genetic basis of 24 important traits related to yield, plant structure, and fruit quality. By using a high-resolution SNP dataset along with an adapted genome-wide association study (GWAS) model, the team identified 62 genomic regions associated...
